Re: [SR-Users] rtpproxy doesn't record after start_recording

[Marko Tirs]

Hi Daniel,


yes, I hear the audio going both ways ok.

In the meantime I succeeded to record something by rtpproxy
but in best case only one direction, I can hear just the callee,
but not the caller.

In the meantime I have used start_recording in route[NATMANAGE]
but before rtpproxy_manage("co"):
--

if (is_method("INVITE") and (status=="200")) {
   start_recording();
} 

rtpproxy_manage("co");
-- 


After reading of your message I tested also with

start_recording after rtpproxy_manage("co"):
-- 
rtpproxy_manage("co");

if (is_method("INVITE") and (status=="200")) {
   start_recording();
}
-- 
But the result was the same:

I have 2 SIP users:
31 (X-Lite on Windows, static address 192.168.0.11)
35 (Android Zoiper, IP address 192.168.0.29 (by DHCP))
Kamailio has static address 192.168.0.13.

When 35 calls 31 then I hear 1 direction in the recorded rtp file,
the voice of callee.
When 31 calls 35 then I don't hear anything in the recorded file.

I don't understand why this difference when user 31 or 35 initiates
a call!?

But I hear audio conversation in both directions, just from the
recorded file in one direction, or even nothing.

I get 2 files per one call: .rtp and .rtcp
How many files should rtpproxy produce for one call?
Should also a file or two for 2nd channel be generated?


How can I record both audio ways?

Thank you
Marko

Hello,

I think you can call the start recording function just after
rtpproxy_manage().

If you don't use the start recording function, is the audio going both
ways without problems?

Cheers,
Daniel

[SR-Users] rtpproxy doesn't record after start_recording

[Marko Tirs]

Hello experts,

I'm newbie in Kamailio and have a problem with my 1st installation.
I just want to control the calls between SIP clients registered by Kamailio
and record the conversations.

I installed rtpproxy and started with
rtpproxy -F -s udp:127.0.0.1:7722 -l 192.168.0.13 -r /home/user1/rtpproxy
-d DBUG:LOG_LOCAL0

After start_recording() in the function onreply_route[MANAGE_REPLY]
rtpproxy creates the files .rtp and .rtcp but they
remain at zero length.

2nd problem is that the media stream is broken in one direction
after start_recording() has been executed, the callee doesn't hear
the caller.

How is the right Kamailio configuration for recording conversations?

Thank you
Regards
Marko

Hello,

you need to run rtpproxy in bridge mode. See the alg example from the

[SR-Users] RTPProxy with VPN

[Rodrigo Moreira]

Hello,

I am having problems with RTPPROXY. I need it to work as a bridge. On one
side will have a VPN tunnel called a tun0, on the other an eth0 interface.
Is it possible for RTPPROXY to run correctly in this scenario?

How can I test if RTPPROXY is running correctly? Is there any command? What
would the configuration look like inside /etc/default/rtpproxy

Please help me.

Best regards

Yep, logs helps. Actually, was mix of errors in PBX and Kamailio config.
So yea, rtpproxy is working as expected, can’t say same for my config files :)

I'd guess rtpproxy_manage() isn't failing, it just isn't called since
dialplan logic is only instructed to do this for natted stuff. Since the
source ip and SDP both contain the same ip the assumption is that
rtpproxy is not needed.

That just sounds like the rtpproxy is not being engaged, i.e. that the 
rtpproxy_manage() call is failing. When that happens, the SDP from .2 will be 
passed through unaltered.

The Kamailio log should give you some idea of why the rtpproxy invocation has 
failed.

RTPProxy is certainly not limited to RFC 1918 addresses or any particular 
network characteristics.

Hi!
Issue I can’t figure out. Or all working ok and that’s just me who not 
understands.

I have situation
softPhone (111.222.3.2) -> Kamailio w. rtpproxy (111.222.3.3) -> PBX 
(111.222.3.4)
All addresses are on same public network.
rtpproxy is running with -l 111.222.3.3 -A 111.222.3.3
I want all media goes through rtpproxy. So, in INVITE and ACK I call 
rtpproxy_manage().
But according to sip packets on PBX (10.0.0.4) I got media address 10.0.0.2 in 
SDP, but not 10.0.0.3

If I use scheme, where client in some other NATted network (like 
192.168.1.100), all is replaced correctly (means rtpproxy_manage() is working)

So, I can’t understand, rtpproxy_manage() changes only rfc1918 addresses or I’m 
missing something?
If any - can provide pcap’s with both cases.

Regards, Igor

Re: [SR-Users] Rtpproxy settings without NAT in Kamailio

[Vladyslav Zakhozhai]

Hi Shantanu,

You need to modify kamailio config to achive your goal. Look into NAT
routing (i.e. NATDETECT and NATMANAGE).

[SR-Users] Rtpproxy settings without NAT in Kamailio

[shantanu saha]

Hello,
I am trying to configure rtpproxy with Kamailio. kamailio.cfg is already
configured (default) for rtpproxy. I just add the following line at the top
of the cfg file.

*#!define WITH_NAT*

After that rtpproxy is working in local network. Both client and sip server
are running in local network.
But when I run this in public network, rtpproxy didn't trigger.

Rtppoxy and Kamailio are running in same public IP, Sip client also running
in another *public IP. *So there is *no NAT* *.*

Both local and public version was Centos 6
Kamailio version : 4.4
rtpproxy version: 2.1

Note: udp connection between rtpproxy and Kamailio was established (both in
public and private network)


Thanks
shantanu saha

[Gholamreza Sabery]

Yes. I finish the session at the end of each call. Also I am using
rtpproxy_manage("r"). My configuration regarding RTPProxy is default config
which comes with Kamailio sample config file.

Re: [SR-Users] RTPProxy benchmark

[Dragos Oancea]

Hi

Increase fs.file-max in your /etc/sysctl.conf .
eg: fs.file-max = 5
And then do sysctl -p
Decrease SILENT_TIMEOUT in your rtpengine.conf (eg:SILENT_TIMEOUT=120) -
it's default 1 hour and if some calls don't have media then rtpengine
will just keep the UDP ports in use until this timeout expires.

Regards,
Dragos

Re: [SR-Users] RTPProxy benchmark

[Daniel-Constantin Mierla]

Are you ending the rtp proxy sessions when the call are ended? What
rtpproxy functions are you using in the configuration file?

Cheers,
Daniel

No not the first time. But over time. I rebooted my system and error is
gone! It seems that it happens over time.

Are you getting the error first time when you reach first 1900 sessions?
Or after a while, after some previous sessions are ended?

Re: [SR-Users] RTPProxy benchmark

[Gholamreza Sabery]

I already set these parameters:

rtpproxy -m 5000 -M 65000

As well limits for number of open files are set to 100 (ulimit -n).
When I increased log level of RTPProxy I saw:
ERR:create_twinlistener:GENERAL: can't create IPv4 socket: Too many open
files in system

Re: [SR-Users] RTPProxy benchmark

[Daniel-Constantin Mierla]

Hello,

first thing to look at is the port range. There are some parameter that
you can provide to rtpproxy in command line in order to increase the
range of port it can use -- see 'rtpproxy -h' or 'man rtpproxy'.

Cheers,
Daniel

Dear Daniel:

I used a single RTPProxy instance. RTPProxy version = 20040107. And yes
there was traffic for all calls but traffic is one-way. One leg sends the
call and the other just receives it.

[SR-Users] RTPProxy benchmark

[Gholamreza Sabery]

I managed to create about 1900 concurrent calls using a single Kamailio and
RTPProxy server. But after this number RTPProxy returns 0 and the following
error is shown in the Kamailio log files:

incorrect port 0 in reply from rtp proxy

What is the problem here? Also number of file descriptors that
RTPProxy can use are set to a million.

Re: [SR-Users] RTPProxy

[Daniel-Constantin Mierla]

Hello,

thanks for all those details, very useful ...

To be clear -- the issue of using high cpu on idle (no active calls) was
with rtpproxy v1.2 on a centos (iirc, v6), not with rtpproxy 2.0. On
debian, same version of rtpproxy was not exposing this. I was just
curios to see if anyone else saw it ... might have been just that system...

Cheers,
Daniel

Re: [SR-Users] RTPProxy

[Maxim Sobolev]

Just a little comment on the numbers that I've thrown out earlier today.
Those are probably somewhat pessimistic, with some creative tuneup you can
probably go much higher. But we also constrained by some other
considerations (i.e. running fully redundant network connection with FEC,
full firewall etc, custom OS), so those are what we get.

Also, I wanted to point to the list, speaking about number of sessions is
pretty much pointless, as the main thing that keeps us busy is packet per
second rate. Since same 10,000 sessions might translate to as much as half
of PPS rate if use 10ms ptype versus 20ms ptype. Our limit at this point of
time is some 450k PPS in and 450k PPS out, 16 cores, FreeBSD 10.3, which
could be either 4.5k sessions with 10ms packets or 9k sessions with 20ms or
somewhere in between if you have mixed traffic (as most of our customers
do). Latest Linux kernels might get better contention control on higher CPU
count systems, or at least it is what I've seen on some of the benchmarks
not so long time ago, We've planned to run some evaluations but have not
got time to do so yet.

On top of that, even if you can push say 1 million PPS through single tuned
up box (10k sessions at 10ms), some other constrains may arise. Most of the
general-purpose DC providers we've encountered in our somewhat limited
practice, design their networks with much lower PPS per port in mind. It's
often an issue with a new DC here that we bump into all sorts of automated
DDoS prevention systems once we reach 100-200k PPS per box/port. So at the
end of the day it might be more practical and economical to run bunch of
the smaller nodes and spread the load across them using something like
rtp_cluster rather than try to cram all that traffic into a single box/port.

Re: [SR-Users] RTPProxy

[Maxim Sobolev]

Arsen, there is no readily-made solution with rtpproxy unfortunately for
that. Some time around 1.0 times circa 2007-2009, somebody submitted a very
rough patch to implement master/hot-standby scenario, but the patch was not
production-ready back then and the contributor was not available to refine
it further, so it ended up stashed somewhere on the branch in git. I'd be
happy to say we are working on that, but our resources are limited and
priority is to get features like SRTP, trans-coding and video support. As
always, pull requests/patches are welcome. With 2.x code is much more
modular, so it should be easier to get something like that working.

Re: [SR-Users] RTPProxy

[Maxim Sobolev]

Daniel, thank you for your interest. Yes, there were many architectural
changes between 1.x and 2.0. The most noticeable is that we've decoupled
I/O from the control channel handling and also split I/O into two threads,
one for poll/receive and the second one for the sending. We've also
refactored our scheduling algorithms to provide much better performance
jitter-wise. There are more threads than two in 2.0, but most of them are
not using much CPU if any. As such as a rule of thumb you'd want to run max
one rtpproxy per two CPU cores with 2.0, up from one instance per core with
1.x. Yes, 1000 bi-directional streams is realistic value, at least in a
situation when you have multiple rtpproxy instances running concurrently on
the box which creates non-trivial overhead in terms of system calls
contention. You can probably go higher than 1,000 if you have single
instance and/or latest CPU. There is detailed 2.0 release notes document
available at our github project.

In terms of cpu usage while idle, I am not aware of any major issues with
2.0. That being said, rtpproxy is known to be somewhat wasteful in general
while running with no load, it still does 200 poll's a second and that
tends to consume <1% of single core CPU per running instance. I've got some
ideas on how to fix it, but that would not be available until 2.2 is out
somewhere in 2017. We are working on getting 2.1 out, which would include
new plain text accounting module more refinements and improvements. Among
those, we've added experimental support for running control channel over
TCPv4 and TCPv6 sockets, still something that needs to be integrated back
into all children of SER.

We are aware that packaging is somewhat behind in some distros*. However,
we ourselves and most of our biggest customers roll their own builds
anyway, so we just rely on the community to take care of. That being said,
we always welcome pull requests to get stuff that might help others to
package it on FooLinux.

Please don't hesitate to ask if something is unclear or if you have more
questions. Thanks!

Hi guys,

In addition to this interesting and useful thread, what is the best way to
implement media session recovery, for example in Active/Passive HA scenario?
I know that it is possible with rtpengine (redis db), is it possible with
rtpproxy?

Thanks,
Arsen.

Re: [SR-Users] RTPProxy

[Daniel-Constantin Mierla]

Hello Maxim,

given the discussion here, I would like to get some updates for myself
regarding 2.0 in terms of capacity and other stuff.

I was using rtpproxy 1.x with kamailio doing load balancing across many
instances of rtpproxy. I was using 1000 streams as estimation for one
instance and I see it's what you mentioned as well. Is it the
recommended (or the good) value for 2.0? Most of deployments still use
v1.2, given it's presence in stable/old OS distros.

It's any relevant architectural change in 2.0? Like more threads used by
the app or other I/O refactoring? Iirc, v1.x uses one for control commands?

I wanted to report at some point, with v1.x, on some centos (iirc), when
there was no active call, rtpproxy was eating a lot of cpu. With a call
(or more) going on, the cpu went to normal. I think it was like waiting
for I/O was using the cpu. Switching to debian was a solution at that
moment, so might not be rtpproxy, but I am wondering if you or anyone
else faced same issue. Also, if I am not wrong, the person that reported
to me said that 2.0 didn't revealed the same behaviour.

Cheers,
Daniel

[Alex Balashov]

And yes, I was remiss in failing to mention that an effective solution 
to scaling out rtpproxy is to bind multiple instances with different 
core affinities.

Re: [SR-Users] RTPProxy

[Maxim Sobolev]

Alex, with all due respect, things you said about rtpproxy capacity is
somewhat outdated and misleading. We have some nodes in the field, that
handle 5,000-6,000 rtp sessions in peak. Those are running 6 rtpproxy
instances, 1,000 sessions each.  2-3 year old CPUs, 12 cores in total.

We also have an open source solution called rtp_cluster, which allows
building larger scale deployments, for at least up to 50,000 bidirectional
streams using multiple nodes running rtpproxy. Available here
https://github.com/sippy/rtp_cluster. You are also welcome to check our
talk last summer at the opensips devsummit in Austin where we gave it some
limelight.

So you are off by two orders of magnitude roughly with regards to the
capacity. :)

And yes, we've been happily running large deployments at AWS for at least 6
years now.

Rodrigo, speaking about your original question, I could not tell much about
rtpengine due to a lack of practical experience with it. But from what I
read on its website it seems to be logical continuation of the mediaproxy
package packed with some cutting edge sexy features.

In a nutshell rtpproxy and mediaproxy/rtpengine are just two independently
developed pieces of software, doing somewhat similar function. What would
work in your particular setting depends on your requirements and
constraints.

Here at Sippy Labs we focus on stability, compatibility and portability for
a predominantly regular audio traffic.

We also have a test suite that check compatibility of the latest production
and development versions of the rtpproxy against array of different SIP
engines, including Kamailio. https://travis-ci.org/sippy/voiptests

So with rtpproxy you are not locked in into single SIP engine, you can mix
and match to fit your particular goal.

And yes, last but not least, all our code is BSD licensed, so you can build
you proprietary box that uses it.

Hope it helps.

rtpproxy is a userspace process which, historically, has a relatively 
limited call throughput capacity (maybe a few hundred calls), though 
this might be addressed to some degree in rtpproxy 2.0. Nevertheless, it 
has been commonly used and well supported in the *SER family for long time.


RTPEngine is a newer initiative from Sipwise, and uses kernel-mode 
forwarding to achieve close to on-the-wire RTP forwarding speeds. It can 
do 10,000+ concurrent bidirectional RTP streams. It also has lots of 
other features which can be useful in, for example, running an RTP relay 
in 1:1 NAT environments such as AWS, or in enabling WebRTC.


However, it is a bit more complicated to set up than vanilla rtpproxy. 
Not much more, though.

Hi again

Yes, i feel very dumb because i actually faced this problem in my testing
with SIPp and with Asterisk before and it was all about open file
description. I probably didnt think about it because I couldnt find
anything in the logs about it which it is quite weird, the only thing that
logs is the one mentioned before, I feel sorry for wasting your time but at
the same time i have to thanks to you guys for helped me out.

Best Regards.

Yes, that's probably it. There should be also some error in the log that
rtpproxy emits, so you might want to check that. I see people run into this
from time to time, perhaps we need to check and put out a big warning in
red if the OS limit appers to be too low?

A guess, but each call takes 4 file descriptors, so you might be running 
into the normal os limit of 1024 open files per process.
Recent rtpproxy versions have the -L option to increase the limit. It 
should be 4 times the number of concurrent calls you expect to handle.


Again, just a guess.

[SR-Users] RTPProxy Issues

[TEG AMJG]

Dear list

I am quite new to Kamailio and i have been able to solve some NAT Traversal
issues with symmetric SIP+RTP putting kamailio+rtpproxy behind NAT, i am
also load balancing some asterisk boxes for transcoding and some other
services like voicemail. Also i am using SIPp for load testing

Now the question is that, while everything is working great with NAT (even
when i am using SIPp for testing with low load) when i am about to test it
with more than 150 calls or something i am starting to get the following
error:

*kamailio[34549]: ERROR: rtpproxy [rtpproxy.c:2735]: force_rtp_proxy():
incorrect port 0 in reply from rtp proxy*

I have been trying to look at some SIP packets when the error starts and i
am not seeing anything out of the normal (while being quite difficult to
debug when having so many concurrent calls at SIP level)

My configuration doesnt have anything new, the only thing is that, because
Kamailio is behind NAT i used some ideas from some other users and debates
from this same mailing list:

*# RTPProxy control*
*route[NATMANAGE] {*
*#!ifdef WITH_NAT*
* if(is_request()) {*
*  if(has_totag()) {*
*   if(check_route_param("nat=yes")) {*
*setbflag(FLB_NATB);*
*   }*
*  }*
* }*

* if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB)))*
*   return;*

* if(!route(FROMASTERISK)){*
*force_send_socket(10.0.1.207);*
*rtpproxy_manage("rw","10.0.1.206");*
* }else{*
*force_send_socket(10.0.1.206);*
*rtpproxy_manage("rw","10.0.5.203");*
* }*

* if (is_request()) {*
*  if (!has_totag()) {*
*   add_rr_param(";nat=yes");*
*  }*
* }*
* if (is_reply()) {*
*  if(isbflagset(FLB_NATB)) {*
*fix_nated_contact();*
*  }*
*#!endif*
* return;*
*}*

This solution is based of someone's idea from this mailing list:
http://lists.sip-router.org/pipermail/sr-users/2013-January/076254.html

As you can see in my configuration, my "public network" is really private
network so i tweak the NATDETECT route to not include RFC1918 networks as
part of the detection

*# Caller NAT detection route*
*route[NATDETECT] {*
*#!ifdef WITH_NAT*

*if (nat_uac_test("1")) {*
*if (nat_uac_test("18")) {*
*force_rport();*
*if (is_method("REGISTER")) {*
*fix_nated_register();*
*} else {*
*fix_nated_contact();*
*}*
*setflag(FLT_NATS);*
*return;*
*}*
* }*
*#!endif*
* return;*
*}*

Also i would like to know how may i use RTPProxy logs?, i tried to
configure it like this:

/etc/rsyslog.conf

*# Kamailio logging*
*local0.*
 -/var/log/kamailio.log*

*#RTPProxy logging*
*local3.*
 /var/log/rtpproxy.log*

/etc/sysconfig/rtpproxy

*OPTIONS="-l 10.0.1.206 -A 10.0.5.203 -s udp:127.0.0.1:7722
 -r /var/lib/rtpproxy/sessions -d DBUG:LOG_LOCAL3 -m
35000 -M 55000 -F"*

I cannot see anyhing in the logs

Thank you very much

Alejandro

[Maxim Sobolev]

We don't support SRTP de/re-encryption at this point, neither in master nor
in 2.0. The work to add it is underway, but we are not quite there yet.
Pass-through mode should be working fine though, we've tested it recently
specifically.

Re: [SR-Users] rtpproxy question

[Albert Petit]

Hi ,

Sorry for previous question. Finally it seems i got confused because
traffic my UA was sending was not properly encrypted .Then when doing
server tcpdump wireshark was seeing it still as RTCP (and not SRTCP) when
jumping on rtpproxy :-) When fixed problem in user agent all traffic is
SRTCP and rtpproxy just bridges it to the destination.

I was thinking of some interaction because new feature at
https://github.com/sipwise/mediaproxy-ng ( (Bridging between RTP and SRTP
user agents) but i understand this feature to decode SRTP can only be
enabled when mediaproxy-ng is used (that feature is not supported by
rtpproxy,  but by mediaproxy-ng correct?).

 BTW can this feature be enabled  easily when mediaproxy-ng is used? Is
that enabled using following flags on rtpproxy_offer etc? (*s, S, p, P* -
These flags control the RTP transport protocol that should be used towards
the recipient of the SDP. If none of them are specified, the protocol given
in the SDP is left untouched. Otherwise, the "S" flag indicates that SRTP
should be used, while "s" indicates that SRTP should not be used. "P"
indicates that the advanced RTCP profile with feedback messages should be
used, and "p" indicates that the regular RTCP profile should be used. As
such, the combinations "sp", "sP", "Sp" and "SP" select between RTP/AVP,
RTP/AVPF, RTP/SAVP and RTP/SAVPF, respectively.)

Thanks
Albert

Re: [SR-Users] rtpproxy question

[Daniel-Constantin Mierla]

Hello,

are you sure rtpproxy 2.0 does encryption/decryption of the RTP/SRTP? I
haven't noticed that the v2.0 has support for such feature.

What are the parameters you are using to control rtpproxy from kamailio.cfg?

Cheers,
Daniel

[SR-Users] rtpproxy question

[Albert Petit]

Hi list

I have installed a newer version of rtpproxy (2.0) in our development
server , i was happy because it brings lot of performance improvements

However i have found an issue when clients use TLS+SRTP

In that scenario i do not want rtpproxy to decrypt/reencrypt the traffic as
my B2BUA does that or in some scenarios we do plan to add end to end
encryption. RTPProxy 1.X was doing that perfectly

Instead since i use rtpproxy 2.0 all SRTP and SRTCP traffic is decrypted by
rtpproxy and i receive it clear in the B2BUA

How can i disable this new feature and that rtpproxy just keeps sending the
received SRTP/SRTCP stream without decrypting it?

Hello,

I am not familiar with the insights of rtpproxy source code, so I don't
know if there is a limitation for duration and for how long it is.

Re: [SR-Users] rtpproxy module question

[gmele]

Hello,

Thx for the explanation, so it means that as soon as the callee connects to the 
RTP Proxy, the rtp proxy will use the callee ip address and port to forward the 
rtp stream and ignore the initial learned ip/port? Is there a duration 
limitation in this learning mode? Meaning that if the callee waits to much to 
send the first udp packet, the rtp proxy will use the ip/port set during 
negotiation?

Thx

Giovanni

Hello,

initially the rtpproxy is in so called learning mode, waiting for the first rtp 
packet to come from each side of the call. Before receiving first rtp packet it 
relies on source ip of signaling.

If the SDP has the device IP (you can eventually set that in the proxy), then 
you can use 'r' flag for rtpproxy_manage() to tell rtpproxy that it should 
trust the IP from sdp.

Daniel

[SR-Users] rtpproxy module question

[gmele]

Hello,

we are using an RTP Proxy from rtpproxy.org as media relay to establish
communication between our mobile phones. Of course, we are using the
kamailio rtpproxy module to modify the SDP payload and control the proxy.

In our Kamailio configuration, we have 1 kamailio configured as Proxy and
one kamailio configured as Registrar. So calls go through the Proxy and then
to the Registrar who will update the SDP header and select an available rtp
proxy.

We have noticed that sometimes, the rtp udp flow between the phones isn't
routed properly by the rtpproxies, ending in the communication drop (all the
SIP nego is working well, and the SDP are correctly patched with the rtp
proxy address and port). 

Analyzing the RTP proxy packets, we have found that the Kamailio registrar
gives the Kamailio proxy ip address in the RTP proxy create session command,
but keeps the original sdp port.
command looks like this:
Uc96,101 DC -PbO~Wnm  
PZU5OITCW;1 

We are using rtpproxy_manage() without any flags.
It seems to us that this ip and port are used as default forward route as
long as the callee hasnt connected to the rtpproxy. *Is it correct?
*
If its true, Its seems to us that this cant work as we are mixing the proxy
sip address with a udp port open on the phone ? *Is our analysis correct ?*

Can we use some option in rtpproxy_manage to replace the proxy ip by the
phone ip as seen in the via route ? 


Thx for your help

Re: [SR-Users] RTPPROXY error message

[Daniel-Constantin Mierla]

Hello,

if rtpproxy is listening on udp:127.0.0.1:7722, then you may have some
limits in place regarding sockets/traffic -- if you have selinux
enabled, try without it. Also, you can try by lowering the value for
children parameter.

Regarding the SQL errors, it seems you run the config from Siremis, but
you haven't created the stored procedures required there.

Cheers,
Daniel

[SR-Users] RTPPROXY error message

[Kevin Greene]

Hi:

I am sure this has been answered before on this list and I have tried the basic
answers I got from Google without any luck. Any suggests would be great.

The Kamailio host is running Oracle Linux 6.7 (64 bit) and is fully patched as
of today.
The Kamailio version is:

Server:: kamailio (4.3.4 (x86_64/linux))
Build:: mi_core.c compiled on 14:25:16 Nov 25 2015 with gcc 4.4.7

I have two major issues:

I am seeing this on my Kamailio log:

Mar 14 21:55:33 sipserver /usr/sbin/kamailio[24005]: ERROR: rtpproxy
[rtpproxy.c:1681]: send_rtpp_command(): can't send command to a RTP proxy
Mar 14 21:55:33 sipserver /usr/sbin/kamailio[24005]: ERROR: rtpproxy
[rtpproxy.c:1716]: send_rtpp_command(): proxy  does not
respond, disable it
Mar 14 21:55:33 sipserver /usr/sbin/kamailio[24005]: WARNING: rtpproxy
[rtpproxy.c:1573]: rtpp_test(): can't get version of the RTP proxy
Mar 14 21:55:33 sipserver /usr/sbin/kamailio[24005]: WARNING: rtpproxy
[rtpproxy.c:1610]: rtpp_test(): support for RTP proxy  has
been disabled temporarily

So the initial thought is that the proxy is not running, however I can see the
proxy is alive:

[root@sipserver boot]# ps -All | grep rtpproxy
5 S   498  2843 1  1  80   0 - 32524 hrtime ?01:29:06 rtpproxy

When I do "netstat -a", I can see 24 established connections.
This is a small sample:

udp0  0 localhost:47937 localhost:rtpproxy 
ESTABLISHED
udp0  0 localhost:38746 localhost:rtpproxy 
ESTABLISHED
udp0  0 localhost:33660 localhost:rtpproxy 
ESTABLISHED

So I am not sure what is going on.

The second problem:

I see this in the Kamailio log:

Mar 14 22:05:33 sipserver /usr/sbin/kamailio[24000]: ERROR: db_mysql
[km_dbase.c:124]: db_mysql_submit_query(): driver error on query: PROCEDURE
kamailio.kamailio_rating does not exist (1305)
Mar 14 22:05:33 sipserver /usr/sbin/kamailio[24000]: ERROR: 
[db_query.c:181]: db_do_raw_query(): error while submitting query
Mar 14 22:05:33 sipserver /usr/sbin/kamailio[24000]: ERROR: sqlops
[sql_api.c:265]: sql_do_query(): cannot do the query [call
kamailio_rating('default')]

When I tried to create the database originally, the script that was part of the
package would not work. I therefore manually created the database so I am
thinking that something got left out. I have been over the schema and I am not
sure what is missing. The database is MySQL (5.5) running in a separate host.

Does anyone have an idea where to look what is missing? I was told that there is
some sort of script that can "repair" the Kamailio schema in the database but I
have not been able to find this magical script.

Thanks.

Kevin

Re: [SR-Users] RTPPROXY issue and sip to sip calling

[SamyGo]

Hi Rehan,

No matter which mode you are running rtpproxy in that IP will always be the
IP of the machine it is running on.
That means that SDP will take that IP once routed to locally subnet A2B
servers.
As far as the A2B detecting SIP user as online or offline based on DB,  I
am not too sure about it. If it is realtime then I think it should work out
of box. You may need to try it out to know it accurately.

Regards,
Sammy

[SR-Users] RTPPROXY issue and sip to sip calling

[Ahmed Rehan]

Dear All

I m trying to setup kamailio and asterisk in load balancing with a2billing
. Currently all of my VMs, one Kamailio and two asterisks are on same
subnet . I have started the RTPproxy like below

./rtpproxy -s udp:127.0.0.1:7722 -l X.X.X.153 -m 1 -M 5 -u root
root -F -d INFO LOG_LOCAL0

My question is if all the VMs are on same subnet with same gateway what
should be written in the private IP X.X.X.153/

Secondly i m authenticating and registering the SIP on kamailio using the
A2B DB . all the dialplan for a2b is being run on asterisk . Now if i want
to call SIP peer to Peer like in case of followme case ,

How should i route the calls in Kamailio ? will it be using usr loc module?
if so any help will be appreciated

I solved this problem by changing the 127.0.0.1 in rtpengine startup config 
into 10.109.247.90 which is the eth0 address of the rtpengine machine.

Now Kamailio successfully connect to the rtpengine daemon.

Re: [SR-Users] rtpproxy does not response, disable it

[Zodiac]

Hi, I am very glad that you can answer me for that.

I’ve already set modparam("rtpengine", "force_send_interface", “10.109.247.80”) 
in my kamailio.cfg from the very beginning.

The port 7723 on 10.109.247.90 which rtpengine daemon runs is not blocked by 
firewall.

There is nothing prompt out on command “kamctl fifo nh_show_rtpp all”

There is nothing captured on "ngerp -W byline -d em1 port 5095” on Kamilio 
machine.

There is an prompt “404 rtpproxy not found” on command “kamctl fifo 
nh_enable_rtpp ump:10.109.247.90:7723 1”

What other reasons can there be for my case?

Furthermore, 10.109.247.80(Kamailio) and 10.109.247.90(rtpengine daemon) are 
both private IP address, not public address. Dose this affect?


This is the kamailio.cfg portion:



This is the rtpengine daemon startup config:

Re: [SR-Users] rtpproxy does not response, disable it

[smititelu]

I’ve already set modparam("rtpengine", "force_send_interface", 
“10.109.247.80”) in my kamailio.cfg from the very beginning.
Can you try force ping from kamailio machine (.80) to rtpengine machine 
(.90), on 10.109.247.80 interface? (it should work)



There is nothing prompt out on command “kamctl fifo nh_show_rtpp all”
If there is nothing shown it means that kamailio sees no rtpengine 
nodes. What kamailio/rtpengine version are you using? (are they both 
latest upstream?!). The sock line should be fine: modparam("rtpengine", 
"rtpengine_sock", "udp:10.109.247.90:7723")


Can you increase the log level(debug=3) and send some debug info on 
what's happening right after you restart kamailio?(for rtpengine module)


There is nothing captured on "ngerp -W byline -d em1 port 5095” on 
Kamilio machine.
Wehn eventually you see something for the show ctl command, you should 
try capturing for dst port 7723, on kamailio machine, to see the 
commands sent to rtpengine.

[SR-Users] rtpproxy does not response, disable it

[Zodiac]

Dear friends,
I am working on a program on Kamailio and rtpengine proxy. I am 
wondering whether can I set Kamailio and rtpengine daemon on different physical 
machines. For example, I set Kamailio on a machine with IP 
address:10.109.247.80, and launch rtpengine daemon on another machine with 
interface parameter as 10.109.247.90 and ng port 7723. I set parameter in 
Kamailio.cfg with modparam(“rtpengine”, “rtpengine_sock”, 
“udp:10.109.247.90:7723”).

Unfortunately I got debug message like this:

ERROR: rtpengine [rtpengine.c:1710]: send_rtpp_command(): can't send 
command to a RTP proxy

ERROR: rtpengine [rtpengine.c:1746]: send_rtpp_command(): proxy 
 does not respond, disable it

ERROR: rtpengine [rtpengine.c:1616]: rtpp_test(): proxy did not respond 
to ping

And, I also tried to set Kamailio and rtpengine daemon in a same 
machine,and use modparam(“rtpengine”, “rtpengine_sock”, “udp:localhost:7723”). 
And Kamailio can work functionally under this situation. rtpengine daemon can 
receive ping message from Kamailio and rtpengine daemon can work as suspected. 
So for the later case, is it supposed that Kamailio be in the same machine with 
same localhost address? Otherwise, what’s the reason for my ERROR?

You can try make use of the below parameter:

# Which local interface/IP should be used for the control channel
modparam("rtpengine", "force_send_interface", "X.X.X.X")

Re: [SR-Users] rtpproxy does not response, disable it

[Alex Balashov]

Yes, you can certainly run rtpengine on a different host than the 
Kamailio host.


Is it possible there are firewall rules on the remote rtpengine host 
that are blocking UDP connections from your Kamailio box to port 7723? 
That would be my first thought.

Hi Zodiac,

1. Can you see your configured rtp node on: "kamctl fifo nh_show_rtpp all" ?
2. Can you ngrep the commands being sent by kamailio to rtpengine?(on 
both kamailio and rtpengine machine)

3. Do you have some firewalling rules that may block that 7723 port?

[SR-Users] rtpproxy does not response, disable it

[Zodiac]

Dear friends,
I am working on a program on Kamailio and rtpengine proxy. I am 
wondering whether can I set Kamailio and rtpengine daemon on different physical 
machines. For example, I set Kamailio on a machine with IP 
address:10.109.247.80, and launch rtpengine daemon on another machine with 
interface parameter as 10.109.247.90 and ng port 7723. I set parameter in 
Kamailio.cfg with modparam(“rtpengine”, “rtpengine_sock”, 
“udp:10.109.247.90:7723”).

Unfortunately I got debug message like this:

ERROR: rtpengine [rtpengine.c:1710]: send_rtpp_command(): can't send 
command to a RTP proxy

ERROR: rtpengine [rtpengine.c:1746]: send_rtpp_command(): proxy 
 does not respond, disable it

ERROR: rtpengine [rtpengine.c:1616]: rtpp_test(): proxy did not respond 
to ping

And, I also tried to set Kamailio and rtpengine daemon in a same 
machine,and use modparam(“rtpengine”, “rtpengine_sock”, “udp:localhost:7723”). 
And Kamailio can work functionally under this situation. rtpengine daemon can 
receive ping message from Kamailio and rtpengine daemon can work as suspected. 
So for the later case, is it supposed that Kamailio be in the same machine with 
same localhost address? Otherwise, what’s the reason for my ERROR?

[SR-Users] RTPPROXY unpredictable behavior

[Javohir Maxmarajabov]

I am trying to enable RTPPROXY on debian, but it seems RTPProxy is ignoring
my arguments...

So, I am launching RTPPROXY using command:

rtpproxy -l _MY_PUBLIC_IP_ -s udp:127.0.0.1 7722 -p /var/run/rtpproxy.pid
-R -a -P -r /tmp/rtppath -S /tmp/rtpspool -u rtpproxy rtpproxy

Also tried with:

rtpproxy -l _MY_PUBLIC_IP_ -s udp:127.0.0.1 7722 -u rtpproxy rtpproxy

And when I try to start Kamailio service I am getting error:

0(10562) ERROR: rtpproxy [rtpproxy.c:1681]: send_rtpp_command(): can't send
command to a RTP proxy

0(10562) ERROR: rtpproxy [rtpproxy.c:1716]: send_rtpp_command(): proxy does
not respond, disable it

0(10562) WARNING: rtpproxy [rtpproxy.c:1573]: rtpp_test(): can't get
version of the RTP proxy

0(10562) WARNING: rtpproxy [rtpproxy.c:1610]: rtpp_test(): support for RTP
proxy has been disabled temporarily

p.s. I have checked RTPPROXY, and I am sure that it is launched

ps aux | grep rtpproxy

returned me:

root 2770 0.0 0.0 19392 480 ? Ssl 04:59 0:00 /usr/bin/rtpproxy -l
_MY_PUBLIC_IP_ -s udp:127.0.0.1 7722 -p /var/run/rtpproxy.pid -R -a -P -r
/tmp/rtppath -S /tmp/rtpspool -u rtpproxy rtpproxy

root 2775 0.0 0.0 11740 932 pts/1 S+ 04:59 0:00 grep --color=auto rtp

Which says everything is ok and rtpproxy is running with arguments that I
declared

But the problem is, When I check it with:

netstat -tulpn | grep rtpproxy

I am receiving:

udp 0 0 127.0.0.1:2 0.0.0.0:* 2853/rtpproxy

As you can see rtpproxy is listening on port 2 and completely ignoring
arguments I declared :(

Where and What am I doing wrong?

Sorry for my English and Thanks in advance...

Re: [SR-Users] RTPPROXY unpredictable behavior

[Carsten Bock]

Hi Javohir,

don't worry, your english is fine.
Can you send us the parameters you have set for rtpproxy in your kamailio cfg?
You should find something like this:

modparam("rtpproxy", "rtpproxy_sock", "udp:localhost:2")

Make sure it matches the configuration of the RTPProxy.

Thanks,
Carsten

[SR-Users] rtpproxy database structure for kamailio 4.2.3

[Jan Hazenberg]

Hi all,

I'm trying to load the rtpproxy url's from database but get a error when 
starting kamailio (4.2.3):


ERROR: db_mysql [km_dbase.c:123]: db_mysql_submit_query(): driver error 
on query: Unknown column 'set_name' in 'field list'


Looks like the field set_name is missing in the database structure, but 
i can't find it in the docs. If i add the field kamailio starts, but 
what is the field set_name used for. Seems it needs to be a int value:


ERROR: rtpproxy [rtpproxy.c:528]: get_rtpp_set(): Invalid set name 
'test' - must be integer



Thanks,

Jan

[Jan Hazenberg]

Daniel,

Clear, i will simply add the field until we can upgrade. Thanks for the 
clarification.

Daniel-Constantin Mierla schreef op 2015-11-19 13:38:

Hello,

it was a different value for column name in the code than in the 
default

rtpproxy table. The definition of the table used setid and the code
set_name. I pushed a fix (in master, 4,3 and 4,2 branches), so the code
is coherent with the database table.

If you don't want to upgrade to latest version in the branch, then have
the set_name column with the same definition of setid column.

Although the type of the column is varchar, it expect to be a number --
from the commit I assumed the developer wanted to extend to non-numeric
set ids, but hasn't done it so far.

If you are not using set ids in the config, you can set the value for
setid/set_name columns to "0".

You can select specific rtpproxy by grouping with a set id -- see:

http://kamailio.org/docs/modules/4.3.x/modules/rtpproxy.html#idp15531672

Cheers,
Daniel

Re: [SR-Users] RtpProxy socket timeout not working

[Daniel-Constantin Mierla]

Hello,

the code shows that is added for U command, if to-tag exists:

https://github.com/kamailio/kamailio/blob/master/modules/rtpproxy/rtpproxy.c#L2692

Can you edit the rtpproxy.c and add a log message (e.g., using
LM_ERR("..."); ) there and is it is printed by kamailio?

Cheers,
Daniel

Hi

Rtp Session timeout notification is not working , we tried with kamailio
4.2 with rtpproxy 2.0 / 1.3 beta/1.2 releases , i think kamailio rtpproxy
is not submitting session timeout socket to rtpproxy

[SR-Users] RTPProxy incorrect port 0 in reply from rtp proxy

[Grant Bagdasarian]

Hello,

I've been load testing kamailio(4.2) with rtpproxy(2.0) using sipp, and when I 
hit 50+ CPS I start getting the following error: incorrect port 0 in reply 
from rtp proxy.
I'm running 4 instances of rtpproxy on the same instance as kamailio.

Could somebody tell me why I'm receiving this error? Do I need to run more 
instances of rtpproxy?

[SR-Users] rtpproxy 2.0

[Klaus Darilion]

Hi!

I just found out that there is a new rtpproxy release:
http://www.rtpproxy.org/post/v2release/

Has anybody tested it and want to share some experiences? Or have people
turned to rtpengine meanwhile? (I am still using rtpproxy 1.2 as I do
not need new features).

regards
Klaus

Upgraded a few servers from RHEL6 to RHEL7, in order to try rtpengine, 
and then got
the chance to briefly test rtpproxy 2.0 as it is default in RHEL7. It 
just works fine, haven't
tested any new options. Only change/improvement we've found is that on 
VMWare the

process is no longer running continuously at 100% CPU.

Have tested it on virtual and physical. Works well, no need to patch for VM or 
advertised address. Had no complaints from users with 1.2 and none since 2.0 

Installed from git for testing.

According to the rtpengine module documentation for
rtpproxy_manage(), that's exactly what rtpproxy_manage() does:



http://kamailio.org/docs/modules/4.2.x/modules/rtpengine.html#rtpengine.f.rtpengine_manage

i.e.

- If INVITE with SDP, then do rtpengine_offer()
- If INVITE with SDP, when the tm module is loaded, mark transaction
with internal flag FL_SDP_BODY to know that the 1xx and 2xx are for
rtpengine_answer()
- If ACK with SDP, then do rtpengine_answer()
- If reply with SDP to INVITE having code 1xx and 2xx, then do
rtpengine_answer() if the request had SDP or tm is not loaded,
otherwise do rtpengine_offer()



What I'm missing there is how to handle an INVITE without SDP. Does that

That's what's supposed to happen, yes.

 i.e.

 - If INVITE with SDP, when the tm module is loaded, mark transaction with
 internal flag FL_SDP_BODY to know that the 1xx and 2xx are for

 - If reply with SDP to INVITE having code 1xx and 2xx, then do
 rtpengine_answer() if the request had SDP or tm is not loaded, otherwise do
 rtpengine_offer()



What I'm missing there is how to handle an INVITE without SDP. Does that
mean, that if we haven't called rtpproxy_manage() on the INVITE, the 1xx or
2xx reply will trigger an rtpproxy_offer instead of rtpproxy_answer?

[SR-Users] rtpproxy-ng and late SDP

[Sebastian Damm]

Hi,

I'm working on a setup, where I have to support late SDP. It is working
right now, but I have to use an explicit rtpproxy_offer() when processing
the reply to an INVITE without SDP.

Is there a way to have rtpproxy_manage() handle those calls automatically?
I was thinking of setting a flag in the request which is used by the
rtpproxy_manage() function later.

Best Regards,
Sebastian

Re: [SR-Users] RTPProxy issue?

[Igor Potjevlesch]

Hello Maxim,

 

Just to let you know that I quick-fixed this issue by increasing the value 
compared into ts_less in rtp.c. Instead of the bitwise calculation, I set the 
maximum value of an unsigned integer.

 

I will schedule to test, qualify and replace all my instances with the new 
version. I will let you know if I reproduce the issue with the new version.

Regards,

 

Igor.

some legacy 1.x code? We've done quite some revamping down there, so that it

Hi Maxim,

 

Hard to do because it's in production.

I have a serious finding since yesterday on how this happened. 

 

My understanding is that the function ts_less returns FALSE into 
rtp_resizer.c because the timestamp between the two packets is  (1  31) 
[for example: 3740425320].

That's result in a drop of any following packets as I can see it into a capture.

Hello,

 

I discovered an issue related to the handling of timestamp and/or Marker

The call-flow is the following: one UA places a call to A and put this call on 
hold. Then, the same UA call another number B. Individual streams are ok.

When the UA tries to transfer A with B, the RTPProxy receive a RTP packet with 
a huge timestamp and the Marker bit set to True.

 

Just after this RTP packet, RTPProxy stop forward the RTP packets from A to B. 
B to C is still working.

 

Anyone have an idea?

 I found this guide for an older version of Kamailio, but there seems

 When I try to start Kamailio i get this :

 It seems it cannot load the rtpproxy module or that force_rtp_proxy
 command does not exist. For Debian the modules are located in
 /usr/lib/x86_64-linux-gnu/kamailio/modules/ and it was found there,
 seems to be loaded in the config file (line 5 and 235). According to
 the rtpproxy doc the module has this command.

 Does anyone have an idea what could be the issue ?


 I am planning to update this guide for the current version once I
 fixed all the issues.
 The most easy issues are the db/usernames/password and the path to the
 modules.

Hi Igor, that's bit strange, since the rtpproxy is not checking any of the rtp 
flags including marker bit. It would help if you can post a tcpdump capture of 
the streams in question along with the log output of the rtpproxy running at 
the dbug level. Thanks!

Re: [SR-Users] RTPProxy issue?

[Maxim Sobolev]

Ah, ok, I see now. I did not realize you guys are using resizer. Which
version of the software are you actually using? I.e. is it latest rel_2_0 /
master, or some legacy 1.x code? We've done quite some revamping down
there, so that it needs to be checked against the very latest code to make
sure. Let us know.

Thanks!

 Hi Maxim,



 Hard to do because it's in production.

 I have a serious finding since yesterday on how this happened.



 My understanding is that the function ts_less returns FALSE into
 rtp_resizer.c because the timestamp between the two packets is  (1 
 31) [for example: 3740425320].

 That's result in a drop of any following packets as I can see it into a
 capture.

 Igor.

[SR-Users] rtpproxy failed to load

[Tom Braarup Cuykens]

kb.asipto.com/kamailio:skype-like-service-in-less-than-one-hour

I found this guide for an older version of Kamailio, but there seems to 
be some issues when trying to use it on the latest stable version.

When I try to start Kamailio i get this :

[] 0(17153) INFO: tls [tls_init.c:399]: init_tls_compression(): tls: 
init_tls: disabling compression... 0(17153) ERROR: core [cfg.y:3286]:

fil[FAILc/kamailio/kamailio.cfg, line 806, column 19: unknown command, 
missing loadmodule? ERROR: bad config file (2 errors) ...


It seems it cannot load the rtpproxy module or that force_rtp_proxy 
command does not exist. For Debian the modules are located in 
/usr/lib/x86_64-linux-gnu/kamailio/modules/ and it was found there, 
seems to be loaded in the config file (line 5 and 235). According to the 
rtpproxy doc the module has this command.


Does anyone have an idea what could be the issue ?


I am planning to update this guide for the current version once I fixed 
all the issues.
The most easy issues are the db/usernames/password and the path to the 
modules.

 You could simply let the RTP traffic to flow directly between FS and

 All you need to do is:
 - forward the appropriate RTP ports to FS;
 - fix the private IP in SDP by replacing it with the public IP for
 the inbound rtp streams (to FS).
 
FS will do this for you if you set the ext-rtp-ip on the profile.

[SR-Users] rtpproxy bridge ie ei behind NAT (like in aws EC2)

[Giovanni Maruzzelli]

dear Kamailians,

I have Kamailio+rtpproxy in front of FreeSWITCH.

Kamailio and FreeSWITCH are on the same private network.
Public Internet IP address ports are redirected to Kamailio and
rtpproxy (same situation as in Amazon EC2).
Clients comes from Internet, and make calls to Internet, SIP signaling
passing through FreeSWITCH (eg: A leg incoming INVITE, FreeSWITCH
originate an outbound B leg INVITE, and then bridge the legs).

Using rtpproxy with -A advertise patch from Daniel, this topology
works fine in a traditional telco way: rtp goes from caller to
rtpproxy to callee, and viceversa.

Now I want to maintain FreeSWITCH in the middle of rtp flow all the
time, in a pure b2bua way, so it can control and analyze the media
streams.

So, I need rtpproxy to act paying attention to direction, as in
caller-rtpproxy-freeswitch-rtpproxy-callee (and viceversa).

Normally I would use Kamailio multihomed and rtpproxy in bridging
mode. But I cannot have a NIC on the public address.

How I can use the ie ei feature of rtpproxy in an Amazon-EC2 like
environment? (eg: no public address attached to machine, but ports
redirection from public address).

I read this trick from Hugh Waite:

I have used rtpproxy (with the advertised address patch) in Amazon to
bridge media between internet facing and private subnets in a VPC.
I found that I couldn’t use different advertised addresses depending
on which direction the signalling was going on a single private IP
address. I worked around this by allocating a second private ip
address to the instance and used that in the ‘bridge’.
-A 54.86.X.X/10.0.1.15 –l 10.0.1.10/10.0.1.15

Can you explain how to use this trick, or another way (without
additional addresses is gladly accepted!) to reach the same result
(rtp always passing through FreeSWITCH) ?

Thank you all in advance,

-giovanni

Re: [SR-Users] rtpproxy bridge ie ei behind NAT (like in aws EC2)

[Daniel-Constantin Mierla]

Hello,

rtpproxy doing bridging requires two network interfaces to work with.

You can try one of the following:
- let freeswitch advertise the public ip for media and skip rtpproxy
completely
- use the second parameter of rtpproxy_manage() to set the advertised ip
address for media and don't configure rtpproxy in bridge mode

Cheers,
Daniel

 I haven't done something like that myself but i think if you use RTPEngine
 with media-address set correctly in offer and answer functions, you can
 easily achieve this. Simply check if request/reply is coming from FS or the
 end-user and adjust the media appropriately without even invoking
 auto-bridge etc.

 Thank you.

 dear Kamailians,

 I have Kamailio+rtpproxy in front of FreeSWITCH.

 Kamailio and FreeSWITCH are on the same private network.
 Public Internet IP address ports are redirected to Kamailio and
 rtpproxy (same situation as in Amazon EC2).
 Clients comes from Internet, and make calls to Internet, SIP signaling
 passing through FreeSWITCH (eg: A leg incoming INVITE, FreeSWITCH
 originate an outbound B leg INVITE, and then bridge the legs).

 Using rtpproxy with -A advertise patch from Daniel, this topology
 works fine in a traditional telco way: rtp goes from caller to
 rtpproxy to callee, and viceversa.

 Now I want to maintain FreeSWITCH in the middle of rtp flow all the
 time, in a pure b2bua way, so it can control and analyze the media
 streams.

 So, I need rtpproxy to act paying attention to direction, as in
 caller-rtpproxy-freeswitch-rtpproxy-callee (and viceversa).

 Normally I would use Kamailio multihomed and rtpproxy in bridging
 mode. But I cannot have a NIC on the public address.

 How I can use the ie ei feature of rtpproxy in an Amazon-EC2 like
 environment? (eg: no public address attached to machine, but ports
 redirection from public address).

 I read this trick from Hugh Waite:

 I have used rtpproxy (with the advertised address patch) in Amazon to
 bridge media between internet facing and private subnets in a VPC.
 I found that I couldn’t use different advertised addresses depending
 on which direction the signalling was going on a single private IP
 address. I worked around this by allocating a second private ip
 address to the instance and used that in the ‘bridge’.
 -A 54.86.X.X/10.0.1.15 –l 10.0.1.10/10.0.1.15

 Can you explain how to use this trick, or another way (without
 additional addresses is gladly accepted!) to reach the same result
 (rtp always passing through FreeSWITCH) ?

 Thank you all in advance,

 -giovanni

 Hi,
 
 There pathch with -A can be found or it is allready implemented into
 specific rtpengine version?

Latest master from git. The command line syntax is a bit different from
rtpproxy, but the basic idea is the same.

Cheers

[Virmantas Variakojis]

Could you provide us a little example? For examlple i have kamailio with
three interfaces: two interfaces (vlan's look at two different providers)
and third interface looks at sip clients.
Thank's in advance!

You would define two interfaces with different names, for example
--interface=public/10.0.1.15!54.86.X.X for outside media and
--interface=local/10.0.1.15 for local media. You would then use two
direction=... options in the offer to determine where A side and B side
are located, respectively. You can also call the interfaces external
and internal and use these flags instead, which mirrors rtpproxy's
behaviour.

Re: [SR-Users] rtpproxy bridge ie ei behind NAT (like in aws EC2)

[Ovidiu Sas]

You could simply let the RTP traffic to flow directly between FS and
endpoints (no need for rtpproxy).
All you need to do is:
 - forward the appropriate RTP ports to FS;
 - fix the private IP in SDP by replacing it with the public IP for
the inbound rtp streams (to FS).
