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

Hi Daniel, I am trying tm.t_uac_start and its stating Content-Type Missing, I have tried to add to params but it doesnt like it, where should it be defined? Command below; jsonrpc_exec('{"jsonrpc":"2.0","method":"tm.t_uac_start","params": ["INFO", "$dlg(to_uri)",".",".","From:$var(testjon)\r\n","To:$var(testjon2)\r\n","Contact:$var(testjon4)\r\n","Content-Type: application/json\r\n","Content-Length: 0\r\n"]}'); And logs; Dec 1 16:09:15 POC_ProxyA /usr/sbin/kamailio[11883]: INFO: <script>: getting here Content-Type missing Dec 1 16:09:15 POC_ProxyA /usr/sbin/kamailio[11883]: INFO: <script>: getting here {"jsonrpc":"2.0","error":{"code":-32000,"message":"Execution Error"}} Thanks Jon ________________________________ From: Daniel-Constantin Mierla &lt;miconda(a)gmail.com&gt; Sent: 01 December 2016 12:31 To: Jonathan Hunter; Kamailio SER - Users Mailing List Subject: Re: [SR-Users] Send SIP Info within a dialog using $uac_req(method)="INFO" Hello, tm.t_uac_start is another rpc command than what was tried before, this one doesn't do async operation.

Ok I will try with the combinations you mention.

Not with the jsonrpc-s module and tm.t_uac_start? When double quotes disappear is likely due to command line interpreter, so you need to put two of them for each one you have now, then ones than need to stay should be with more backslashes. Also, you can try to use single quotes to enclose the parameter values and let the double quotes in the content of the parameter.

So in my kamailio.cfg script file I set the variable; $var(testjon8) = "p1=\"STOP\""; xlog("L_INFO","We are going to try and use $var(testjon8)\n"); And when seeing in the logs I see it states; We are going to try and use p1="STOP" And p1="STOP" is exactly what I want. However when I generate the SIP INFO message, and check on the wire using wireshark I see; Event:p1=STOP So it doesnt have the double quotes I would like. How can I escape them so the t_uac_dlg command includes them? The portion where this header is generated in the command is; exec_avp("kamctl mi t_uac_dlg INFO $dlg(to_uri) . . \\\"From:'$var(testjon)'\"\\r\\nTo:$var(testjon2)\\r\\nCall-ID:$var(testjon3)\\r\\nAllow:$var(Allow)\\r\\nContact:$var(testjon4)\\r\\nEvent:$var(testjon8)\\r\\n\\\"\"", "$avp(test)"); And also running debug I see it as Event:p1="STOP"\r\n\"" Can you tell me how I can escape " so its actually within the SIP header itself?

It is not waiting for the reply of the generated request and you can use it with json rpc exec function in the config, so it avoids using exec. Can you give it a try? Some documentation can be found in the comments of the function used by this command: - https://github.com/kamailio/kamailio/blob/master/modules/tm/rpc_uac.c#L399 Cheers, Daniel On 22/11/2016 18:35, Jonathan Hunter wrote: Hi Daniel, Thanks here you go; [root@POC_ProxyA kamailio]# kamctl mi t_uac_dlg INFO sip:3003@193.144.1.112 . udp:10.70.1.136:5060 \"From:sip:1234@8.8.8.8"\r\nTo:sip:3003@193.144.1.112\r\nContact:sip:daemon@8.8.8.8\r\n\<sip:3003@193.144.1.112%5Cr%5CnContact:sip:daemon@8.8.8.8%5Cr%5Cn%5C>"" 404 Invalid local socket [root@POC_ProxyA kamailio]# VERBOSE=1 kamctl mi t_uac_dlg INFO sip:3003@193.144.1.112 . udp:10.70.1.136:5060 \"From:sip:1234@8.8.8.8"\r\nTo:sip:3003@193.144.1.112\r\nContact:sip:daemon@8.8.8.8\r\n\<sip:3003@193.144.1.112%5Cr%5CnContact:sip:daemon@8.8.8.8%5Cr%5Cn%5C>"" database engine 'MYSQL' loaded Control engine 'FIFO' loaded entering fifo_cmd t_uac_dlg INFO sip:3003@193.144.1.112 . udp:10.70.1.136:5060 "From:sip:1234@8.8.8.8 To:sip:3003@193.144.1.112 Contact:sip:daemon@8.8.8.8 " 404 Invalid local socket FIFO command was: :t_uac_dlg:kamailio_receiver_23469 INFO sip:3003@193.144.1.112 . udp:10.70.1.136:5060 "From:sip:1234@8.8.8.8 To:sip:3003@193.144.1.112 Contact:sip:daemon@8.8.8.8 " Thanks Jon Daniel-Constantin Mierla http://twitter.com/#!/miconda<http://twitter.com/#%21/miconda> - http://www.linkedin.com/in/miconda Kamailio Advanced Training, Berlin, Nov 28-30, 2016 - http://www.asipto.com -- Daniel-Constantin Mierla twitter.com/miconda -- linkedin.com/in/miconda Kamailio World Conference - May 8-10, 2017 - www.kamailioworld.com<http://www.kamailioworld.com> -- Daniel-Constantin Mierla www.twitter.com/miconda<http://www.twitter.com/miconda> -- www.linkedin.com/in/miconda<http://www.linkedin.com/in/miconda> Kamailio World Conference - May 8-10, 2017 - www.kamailioworld.com<http://www.kamailioworld.com>
