[SR-Users] Send SIP Info within a dialog using $uac_req(method)="INFO"

Tue Nov 22 10:00:17 CET 2016

Hello,

One last question relating to this issue of sending SIP INFO within a dialog. (Sorry!)

As you know I now have t_uac_dlg working with the exec module to create the SIP INFO, however how do I inject it effectively within the dialog?

I have added event_route[dialog:start] as thought this would be a good point to send prior to the ACK and just checking I get all the tags for the dialog, however it doesnt seem to capture the to_tag when its hit, am I missing something in config here or am I calling in in wrong place?

event_route[dialog:start]
{
xlog("L_INFO", "We are getting here in event route\n")
xlog("L_INFO","We have here $dlg(to_uri) and $dlg(from_uri)\n");
xlog("L_INFO","to uri is $dlg(to_uri)\n");
xlog("L_INFO","to tag is $dlg(to_tag)\n");
xlog("L_INFO","from uri is $dlg(from_uri)\n");
xlog("L_INFO","from tag is $dlg(from_tag)\n");
xlog("L_INFO","callid is $dlg(callid)\n");

Nov 22 08:53:16 POC_ProxyA /usr/sbin/kamailio[9036]: INFO: <script>: We are getting here in event route
Nov 22 08:53:16 POC_ProxyA /usr/sbin/kamailio[9036]: INFO: <script>: We have here sip:782607917190438 at 4.4.4.4:5060 and sip:01162292700 at 8.8.8.8:5080
Nov 22 08:53:16 POC_ProxyA /usr/sbin/kamailio[9036]: INFO: <script>: to uri is sip:782607917190438 at 4.4.4.4:5060
Nov 22 08:53:16 POC_ProxyA /usr/sbin/kamailio[9036]: INFO: <script>: to tag is <null>
Nov 22 08:53:16 POC_ProxyA /usr/sbin/kamailio[9036]: INFO: <script>: from uri is sip:01162292700 at 8.8.8.8:5080
Nov 22 08:53:16 POC_ProxyA /usr/sbin/kamailio[9036]: INFO: <script>: from tag is as5a4ffcca

As when I do kamctl mi dlg_list I see the totag listed;

[root at POC_ProxyA kamailio]# kamctl mi dlg_list
dialog::  hash=24:6960

        from_uri:: sip:01162292700 at 8.8.8.8:5080
        from_tag:: as5a4ffcca

        to_uri:: sip:782607917190438 at 4.4.4.4:5060
        to_tag:: 3688793392-940006

Sorry again for another question on this theme but I feel I am 90% there thanks to your help.

Also Is it possible to fire the exec command after the completion of the 200ok/ACK exchange ?

Many thanks

Jon

Hello,

Thanks Daniel, knowing how I should specify all the parameters would be great, just a syntax example, in particular when defining all the sip headers and why their are double quotes/single quotes or what best method is.

Thanks again and sorry for the noise!

Jon

something seems to be strange with interpreting the parameters from command line and forwarding them to kamailio. I will dig a bit into kamctl and come back with some hints.

Cheers,
Daniel

Hello.

This is running from command line, not withing the configuration file, so I am testing before I try to add it in.

I have tried with single quotes, but not sure how to enclose the SIP headers and the r/n , can you please advise?

kamctl mi t_uac_dlg INFO sip:3003 at 193.144.1.112 . udp:10.70.1.136:5060    \"From:sip:1234 at 8.8.8.8"\r\nTo:sip:3003 at 193.144.1.112\r\nContact:sip:daemon at 8.8.8.8\r\n\""

As I have tried;

kamctl mi t_uac_dlg 'INFO' 'sip:3003 at 193.144.1.112' '.' 'udp:10.70.1.136:5060'    'From:sip:1234 at 8.8.8.8'r\n'To:sip:3003 at 193.144.1.112'\r\n'Contact:sip:daemon at 8.8.8.8'\r\n\'

And still get invalid socket, as it is including all the SIP headers in with the port parameter so I presume I am missing an operator?

/usr/sbin/kamailio[28999]: ERROR: <core> [main.c:1128]: parse_phostport(): too many colons in udp:10.70.1.136:5060From:sip:1234 at 8.8.8.8rnTo:sip:3003 at 193.144.1.112rnContact:sip:daemon at 8.8.8.8rn'

Its including them all as the local socket/port.

Thanks

Jon

Hello,

Ok great thanks Daniel.

One final thing, I cant seem to get kamilio to except the parameter when I add the socket parameter in the kamctl mi t_uac_dlg command.

If I add as below I get 404 invalid local socket;

 kamctl mi t_uac_dlg INFO sip:3003 at 193.144.1.112 . udp:10.70.1.136:5060    \"From:sip:1234 at 8.8.8.8"\r\nTo:sip:3003 at 193.144.1.112\r\nContact:sip:daemon at 8.8.8.8\r\n\<sip:3003 at 193.144.1.112%5Cr%5CnContact:sip:daemon at 8.8.8.8%5Cr%5Cn%5C>""

do you run this command from command line or from kamailio.cfg? I think it's good to be sure it works from command line.

Also, can you try to enclose each parameter in single quotes -- then it's easier for the command line parser to identify the parameters.

Cheers,
Daniel

404 Invalid local socket

As its picking up the socket with the from address included as well, is this again around syntax?

ERROR: <core> [main.c:1128]: parse_phostport(): too many colons in udp:10.70.1.136:5060"From:sip:1234 at 8.8.8.8

As it seems to pick socket up ok;
