[SR-Users] Call Transfer Scenario Using Freeswitch

2018-08-20 Thread Sunil More 
Hi All,

I am using kamailio and freeswitch in my setup. While all users are
registered on Kamailio, calls are routed to Freeswitch back to kamailio and
then upstream providers.

I can make user to user calls but in cases of transfer I am stuck. I am
using a Polycom IP phone to test this scenario. While I initiate a attended
transfer and click on transfer all the legs hangup.

When I register all users on Freeswitch this works well. I am missing
something on Kamailio side.

Please point me in the right direction.

Thanking You,
Sunil More

[SR-Users] Best practice/routing block for TCP connection errors to UAC?

2018-08-20 Thread Anthony Alba 
HI SR-Users

Scenario: clients registered by TCP/TLS dropping off the network,
kamailio stil thinks the client is registered and relays the INTIVE.
The error occurs at the TCP layer so no failure route is called.


ERROR:  [core/tcp_main.c:2690]: tcpconn_1st_send(): connect
127.0.0.1:48338 failed (RST) Connection refused
ERROR:  [core/tcp_main.c:2700]: tcpconn_1st_send():

ERROR: sl [sl_funcs.c:362]: sl_reply_error(): stateless error reply
used: I'm terribly sorry, server error occurred (1/SL)

I want to send the caller instead a graceful failure route type
message as if the callee is not registered (404/486/603/408 type) but
don't understand how to hook a routing block for TCP errors.

Hello Abdulaziz,

Kamailio gets during compilation some default configuration path, which might 
point to the old (wrong) location. Have a look to the 'kamailio -f' output to 
see its default, you can also use the '-f' parameter to change this location. 
You get all parameters with 'kamailio -h'

Then try again with the debugging method you choose above.

Best regards,

Henning

Hi Kevin,

here you find a (older) presentation about a setup with private asterisk and 
kamailio as network edge. This is the one that we build back in the days at 
1&1, slide 19 has a schematic diagram of the setup:

This is fine, and you can make your outbound calls in that fashion. You do
need to have Asterisk present enough information that Kamailio is aware of
how to route that outbound INVITE request, but if you have sufficient
information in the request URI, it can certainly make that decision.

If, however, you wanted to dial PJSIP/1000 - which no other information and
where 1000 is some registered device - Asterisk will need the registered
contact that the device has presented to the registrar. In which case, you
have to have some mechanism for Asterisk to get at that information.

The historical problem with this "dial endpoints over a trunk peer"
approach is that such endpoints are not as privileged by Asterisk as
local AstDB bindings for various Class 5 / application purposes, e.g.
hints, voicemail, MWI, etc.

But as I understand it, PJSIP is supposed to fix this problem and make
use of an outboard registrar a lot more transparent.

so you should set   more priority to second rule (for avoid 200 to 100

For balancing you may look for another modules, like drouting or dispatcher
Or use different DPIDs within dialplan: DPID may be chosen by $RANDOM (from
cfgutils module)

It is correct (as it is intended). AFAIK your only other choice is to
take matters in your own hands and generate the OPTIONS yourself outside
of kamailio.

hi.
It is ok; nathelper sends OPTIONS for UDP only,
TCP  is managed by core (by using params like "tcp_keepalive")

[SR-Users] Kamailio 5.1 Nathelper sipping on different transport protocols.

2018-08-20 Thread Володимир Іванець 
Hello everyone!

I have system with Kamailio v5.1 which needs to send OPTIONS packets to all
active clients. Here is full Nathelper module configuration:

*modparam("nathelper", "received_avp", "$avp(s:received)")*
*modparam("nathelper", "natping_interval", 30)*
*modparam("nathelper", "ping_nated_only", 0)*
*modparam("nathelper", "sipping_bflag", FLB_SIPPING)*
*modparam("nathelper", "sipping_from", "sip:pin...@kamailio.org
")*

It works fine if client is connected over UDP. But as soon as I will switch
to TCP or register with client that uses WS, Kamailio stops generating
OPTIONS.

Does anyone know if it is  correct behavior or something is wrong?

Thanks a lot!

Re: [SR-Users] What is the typical network setup for kamailio?

2018-08-20 Thread Matthew Jordan 
For what it's worth, we've set up a network/system where Asterisk resides
completely on a private network with Kamailio acting as an edge proxy.
RTPEngine is necessary as well to help the media through to the private
network, but that's probably not surprising. It is completely doable,
although the suggestions below about simply restricting Asterisk on a
public network to the locations of the Kamailio proxies also works quite
well.

Matching inbound requests in Asterisk to only the pool of Kamailio proxies
can be done in a variety of fashions - IP address matching being the
simplest. You will obviously need to think carefully about how Asterisk
handles its outbound calling. If Kamailio is going to act as your
registrar, then you will need to find some way to expose the registered
contacts to Asterisk - we chose this route, and wrote a small REST sidecar
to Kamailio for that purpose. If Asterisk is going to act as your
registrar, you will need to fork the REGISTER requests to all of the
Asterisk instances. Additionally, for INVITE requests being initiated by
Asterisk, you will want to force those to flow through your edge proxies.
This can be done using Asterisk's outbound_proxy setting on the AOR object
in pjsip.conf.

[SR-Users] Dialplan priority

2018-08-20 Thread igor.potjevlesch 
Hello,

 

I'm not sure to understand in which situation "pr" value is used. For
example: if I have two identical rules except pr value: 1 with 1 and the
second with 2, then the rule with pr 2 is never used.

 

Someone can help me to understand? Thank you.

 

The finality I'd like to accomplish is having some kind of load balacing
between two values into "repl_exp" with the same inputs conditions.

 

Thank you.

MySQL is no longer part of Debian. Instead they now use the MySQL fork MariaDB.
So instead of
mysql-server use maria-db-server

all the rest of the steps are the same.

Re: [SR-Users] What is the typical network setup for kamailio?

2018-08-20 Thread Kevin Olbrich 
Hi Henning,

I browsed the files but was unable to find one using Kamailio as SBC
without exposing the Asterisk core.
Most examples indeed expose the node and let media flow directly (
https://www.kamailio.org/events/2017-KamailioWorld/Day1/08-David.Casem-Building-A-Global-VoIP-Network.pdf
- interesting solution with e/iBGP which we would also be able to deploy).

There was just a single presentation that I was able to locate that had the
proxy only on the edge:
https://www.kamailio.org/events/2017-KamailioWorld/Day2/15-Sebasitan.Damm-Anti-Fraud-With-HTables.pdf
At least it looks like they are located behind the SBC.

After the research my impression is, that co-locating the B2BUA with the
Edge-Proxy and firewall-ing it, seems best practice.
We will try to add some security by bridge-firewalling and BGP.

If anyone has a hint for a presentation with high-security edge-proxy, I
would appreciate it. Thank you.

Kind regards,
Kevin

Re: [SR-Users] Releasing Kamailio v5.1.5

2018-08-20 Thread Daniel-Constantin Mierla 
Hello,

short reminder that 5.1.5 is planned for mid of this week -- I
backported many patches by end of last week, but it would be good that
everyone checks to see if all patches relevant for own deployments were
pushed to 5.1 branch.

Cheers,
Daniel

[SR-Users] ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed

2018-08-20 Thread Abdulaziz Alghosh 
Greetings,

i am at the final stages of emigrating from kamailio 3.0.3 to 5.1.0
including our own module. Unluckily, after writing the command " kamctl
start", the following error is popping up:


* PID file /var/run/kamailio.pid does not exist -- Kamailio start failed*

Thus, I used the command " kamailio -M 8 -E -e -dd " to get more debugging
Info and the output is detailing the following:

 0(10334) ERROR: db_mysql [km_my_con.c:129]: db_mysql_new_connection():
driver error: Can't connect to MySQL server on '192.168.1.207' (4)
 0(10334) ERROR:  [db.c:318]: db_do_init2(): could not add connection
to the pool 0(10334) ERROR: ABDUL_functions [ABDUL_chk.c:1069]: init_db():
failed to connect database URL=mysql://ABDUL:ABDUL@192.168.1.207/ABDUL
 0(10334) ERROR: ABDUL_functions [ABDUL_functions_mod.c:296]: mod_init():

 0(10334) ERROR:  [core/sr_module.c:991]: init_mod(): Error while
initializing module ABDUL_functions
(//lib64/kamailio/modules/ABDUL_functions.so)

Seemingly the error relates to old databases url ( "URL=mysql://
ABDUL:ABDUL@192.168.1.207/ABDUL" ) inside an old Kamailio.cfg file from my
3.0.3 package which I put under another different directory. This old
Kamailio.cfg file #includes my own module, so he is exporting this url.
Consequently, my module is trying to connect again to this databases.

I do not know why both kamailio.cfg (new: /etc/kamailio/kamailio.cfg and
old one out of /etc/kamailio) are both seen for kamctl or (/sbin/kamailio).
I know that my new url inside the new /etc/kamailio/kamailio.cfg is read
and connected but again not sure why my hidden old kamailio.cfg is still
being read as well.

the attached shows my init file for "SUSE Linux Enterprise Server 11
(x86_64)" and my used kamailio *default *file under /etc/default.

Thanks in advance and best regards
Abdulaziz

Re: [SR-Users] remove_hf function in INVITE message

2018-08-20 Thread Daniel-Constantin Mierla 
The message is broken indeed, at the part:

Max-Forwards: 69
   
sip:7000@192.168.122.1:36853;transport=UDP;alias=192.168.122.1~36853~1To:


Likely that is because you do couple of operations over the Contact
header, besides remove_hf()/append_hf(), you use also
set_contact_alias() or add_contact_alias(). You can do
msg_apply_changes() in between such operations to avoid breaking the sip
message.

Cheers,
Daniel
