Hi Daniel,


Thanks again for the response, I presume I have to be careful with the characters and syntax for the exec command ?


I will try it out and let you know.


Many thanks


Jon

Hello,


as I can see in the logs, the rpc command fails to execute because it requires async processing which is not implemented by jsonrpc-s module. Then it is an INVITE received:


ct  7 13:45:36 POC_ProxyA /usr/sbin/kamailio[6572]: INFO: <script>: Try and issue command via RPC

Oct  7 13:45:36 POC_ProxyA /usr/sbin/kamailio[6572]: INFO: <script>:  route EXTENIN-We have an Invite here from 209-thirdlane check Hash table trans to see if there

A solution for now would be to run the mi command via exec module.

Cheers,
Daniel

Hello,


Please see debug output for when I try and send the SIP INFO when I am initiating a new call.


I am just testing out the command currently, in practice I will look to inject the SIP INFO into an already formed dialog, so is the way I am trying to test cause me an issue?


I can see;


Oct  7 13:45:36 POC_ProxyA /usr/sbin/kamailio[6572]: DEBUG: tm [uac.c:249]: t_uac_prepare(): DEBUG:tm:t_uac: next_hop=<sip:kamailio.org>


Which will be why its sending the sip info to sip:kamailio.org I presume.


See some output from the relevant process below;


Thanks

Hello,


I looked quickly at the code and the mi command should take the values from the parameters. Can you run with debug=3 and get all the logs messages to see if we can spot something threre.


Cheers,
Daniel

Hi,


Sorry Daniel, let me be clear.


Correct the To/From are not taken from the rpc command, the INFO is triggered/sent but with the To/From of the new request coming in;


Below I dial 07917190438 from ext 209 and this INFO is sent;



INFO sip:kamailio.org SIP/2.0
Via: SIP/2.0/UDP 8.8.8.8;branch=z9hG4bK63d7.374d4573000000000000000000000000.0
To: <sip:07917190438@8.8.8.8>
From: <sip:209@8.8.8.8>;tag=c32652d8e50f480c90e2f8379a0698aa-ea50
CSeq: 10 INFO
Call-ID: YWFhMmVmMzUxM2Q2YzUwMzZhOTFjNDc4OGZlYmM2N2I
Max-Forwards: 70
Content-Length: 0
User-Agent: HA PBX

However this command is triggered to send the INFO and the To/From/Contact are not changed/added;

jsonrpc_exec('{"jsonrpc":"2.0","method":"mi","params": ["t_uac_dlg", "INFO", "sip:3003@8.8.8.8",".",".","From:sip:1234@2.2.2.2","To:sip:3003@8.8.8.8","Contact:sip:1234@2.2.2.2"]}');


I assumed (possibly incorrectly) you can get the command to overwrite the current contents of the headers, so as above the RURI would change to sip:3003@8.8.8.8 and the From to sip:1234@2.2.2.2 etc, however they remain unchanged.

Does that make sense?

Thanks

Jon

Hello,


what do you mean by "with default parameters" in your last remark? Are the To/From not taken from the rpc command?


Cheers,
Daniel

Hi Daniel,


That works in terms of clearing the error, however I just see kamailio send a SIP info message to kamailio.org, as apposed to the RURI I provide, I presume again this will just be putting the t_uac_dlg parameters in the correct order?


Parameters:

  • method - request method

  • RURI - request SIP URI

  • NEXT HOP - next hop SIP URI (OBP); use “.” if no value.

  • socket - local socket to be used for sending the request; use “.” if no value.

  • headers - set of additional headers to be added to the request; at least “From” and “To” headers must be specify)

  • body - (optional, may not be present) request body (if present, requires the “Content-Type” and “Content-length” headers)

As looks like I am defining things correctly now but its not picking them up, again if I run manually it works in command line;


jsonrpc_exec('{"jsonrpc":"2.0","method":"mi","params": ["t_uac_dlg", "INFO", "sip:3003@8.8.8.8",".",".","From:sip:1234@2.2.2.2","To:sip:3003@8.8.8.8","Contact:sip:1234@2.2.2.2"]}');

All I see it fire is an INFO message to Request-Line: INFO sip:kamailio.org SIP/2.0, with default parameters.


Thanks


Jon
