Re: [SR-Users] Re-use TCP connections on different transactions

[Joel Serrano]

Hi Yuriy,

Thanks for your suggestion, I've tried tcp_accept_aliases=yes in config and
I added force_tcp_alias() in the request route, but I haven't seen any
changes.

All the VIA headers look exactly the same, and I still get this in the logs:

"message":" DEBUG: {1 11762916 BYE d2T9-YOxYk} 
[core\/tcp_main.c:2060]: tcp_send(): no open tcp connection found, opening
new one"}


The docs say:

"force_tcp_alias(port)

adds a tcp port alias for the current connection (if tcp). Useful if you
want to send all the trafic to port_alias through the same connection this
request came from [it could help for firewall or nat traversal]. With no
parameters adds the port from the message via as the alias. When the
“aliased” connection is closed (e.g. it's idle for too much time), all the
port aliases are removed."

I tried also using force_tcp_alias(5353) as an example, just to see if I
find "5353" added to any headers, but no luck, it wasn't added anywhere..


Any other suggestions? Am I missing something?


Thanks,

Joel.

Hello Igor,

functional extensions like this will be usually not be backported to older 
stable releases.

But you should be able to easily apply the patch to your local copy, if you 
build from tar anyway.

This is the patch, you can apply with the command "patch":

https://github.com/kamailio/kamailio/commit/038158c99da96933c26b11a919ed1cbe29af9fab.patch

Cheers,

Henning

Hello,

I will think what would be good ways to optimizie.

If you want to change the code, probably doesn't make sense to revert the 
entire patch locally, just allow '_' -- you should change:

if(!isalnum(*p) && (*p != '.') && (*p != '-')) {

to

if(!isalnum(*p) && (*p != '.') && (*p != '-') && (*p != '_')) {

in src/core/parser/parse_uri.c -- see function parse_uri() and case URI_HOST_P.

Hello,

I haven't authored that patch and also never needed an underscore in host part 
of the URI, but also it didn't affect me before that change. I guess Juha 
wanted o be compliant with the RFC.

If people need to allow an extended set of chars in the host part, I am fine to 
add some parameter to control that.

Hello,

reading again I see that the error with the host uri is printed from the C 
code. I thought of another issue that was reported related to IPv6 addresses in 
the URI that kamctl rejected.

The problem is that the underscore is not allowed in hostname: the relevant 
standard is RFC 1123, section 2.1 "Host Names and Numbers" which limits host 
names to letters-digits-hyphen.

I checked the commits log and it seems this more strict verification was added 
by next commit:

commit 4994960324d5353222b3de08515bed07802ab7bc
Author: Juha Heinanen 
Date:   Wed Jan 10 08:39:48 2018 +0200

core/parser: more strict parsing of sip uri host

Regarding the $ALL_METHODS not being defined, iirc, you should set it to . (or 
maybe -1 in this case).

Re: [SR-Users] How to use sdp_remove_media() ?

[Karsten Horsmann]

Hi Denys,

AFAIK read and writes rtpengine the complete sdp. So manipulating with the
"classic" textops tools is more for RtpProxy. You can search for things but
writing will done by rtpengine.
I remove for example an codec with codec-mask. Or you can manipulate the
avp you read from rtpengine (via modparam) in the request.

Did you try to *codec-mask= in the rtpengine calls (answer / manage)? *
*So rtpengine takes care for the removal. *
*It needs to know what to remove. *

Re: [SR-Users] How to use sdp_remove_media() ?

[Daniel-Constantin Mierla]

Hello,

that's strange, because the condition in the c code is:

    if(msg->first_line.type != SIP_REPLY && get_route_type() !=
REQUEST_ROUTE) {
        LM_ERR("invalid usage - not in request route or a reply\n");
        return -1;
    }

Which is clear about whether the message is a SIP reply or function is
executed in request_route. There is a condition later about the
record_route(), but it didn't get to that code...

Maybe you can share the entire request_route you had when the error was
exposed.

Cheers,
Daniel

Got message in debug=3:

But definitely msg_apply_changes() is placed in request_route section.
I have just moved code part before calling record_route() function and it
helped.

Interesting, but as I remember Kamailio should display in such cases
something like below:
"...cannot apply msg changes after adding record-route header..."

Thanks for the hint.

Re: [SR-Users] Phonenum module

[Daniel-Constantin Mierla]

Yes, it should be a leading + to make it international, because that
number can be a local one in Germany -- in many countries the phone
number length can vary, not like in US where is fixed size.

phonenum has also some overhead if you just want to see if it is a
number, maybe next one is better:

Re: [SR-Users] Phonenum module

[Igor Olhovskiy]

That's the main problem here.

I just need to verify, that number came is valid. I don't have any info on 
country code (means I can do a sort of regex match, but it will be overkill)
But why number is not in international format? Or should I add leading "+"?

Re: [SR-Users] Phonenum module

[Daniel-Constantin Mierla]

Hello,

probably you have to use the function that has the country code:

  -
https://kamailio.org/docs/modules/stable/modules/phonenum.html#phonenum.f.phonenum_match_cn

Because the number is not in international format.

Cheers,
Daniel

Re: [SR-Users] Phonenum module

[Daniel-Constantin Mierla]

Hello,

can you try with the first parameter in between double quotes ("$fU")?

Otherwise, set debug=3 and provide all log messages printed by kamailio
when executing the phonenum_match() function.

Cheers,
Daniel

[SR-Users] How to use sdp_remove_media() ?

[Denys Pozniak]

Hello!

I'm trying to remove m=video stream from incoming SIP/SDP request in th way
below:

modparam("rtpengine", "read_sdp_pv", "$avp(read_sdp_pv)")
modparam("rtpengine", "write_sdp_pv", "$avp(write_sdp_pv)")
...
  sdp_remove_media("video");
  msg_apply_changes();
  sdp_get("$avp(read_sdp_pv)");
  xlog("L_WARN","[$cfg(route)] *m=video removed* ci| rb=/$rb/ \n");
  xlog("L_WARN","[$cfg(route)] *m=video removed* ci|
avp(read_sdp_pv)=/$avp(read_sdp_pv)/ \n");
  rtpengine_manage("$avp(rtpengine_offer)");
  set_body("$avp(write_sdp_pv)", "application/sdp");

But no luck, xlog shows m=video in $rb and $avp(rtp_sdp_read) as well.

[SR-Users] Phonenum module

[Igor Olhovskiy]

Hi!

I'm playing around libphonenum to get validation accross e.164 numbers.

So, idea is simple
if (phonenum_match($fU, "src_num")) {
if ($phn(src_num=>valid) != 1) {
send_reply("400", "Invalid e.164 format");
xlog("L_ALERT","ALERT: FU: $fU is not e.164 number $phn(src_num=>error)\n");
exit;
}
}

But on every (actually valid e.164 number like 380442459966 or 61388141397) I 
got Parsing number failed in error result.
Tried both phonenum_match($fU, "src_num") and phonenum_match("$fU", "src_num")
Actually phonenum_match("380442459966", "src_num") also not working

Re: [SR-Users] kamailio on kubernetes

[Sergey Safarov]

This will work if you get static IP for kubernetes host.

https://github.com/kubernetes/kubernetes/issues/80122
https://github.com/aws/amazon-vpc-cni-k8s/issues/652
https://github.com/cbeneke/hcloud-fip-controller
https://docs.projectcalico.org/v3.10/networking/add-floating-ip

And then start kamailio container with host network

Also you can customize kubernetes nodegroup init scripts or image to
assign static IP at node boot procedure.
As example assign network interface with preconfigured private IP and
elastic for Amazon cloud.
