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

Mon Nov 14 21:04:33 CET 2016

Hi Daniel,

I am just trying to put the mi command into jsonrpc_exec and looking at the documentation, Im not sure in this instance how to put down multiple parameters.

Running this command works in command line;

kamctl mi t_uac_dlg INFO sip:3003 at 193.144.1.112  . . \"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\""

However if I then look to run it, I have tried the following (amongst other variations);

jsonrpc_exec('{"jsonrpc":"2.0","method":"mi","params": ["t_uac_dlg", "INFO", "sip:3003 at 193.144.1.112",.,.,"From:sip:1234 at 8.8.8.8","To:sip:3003 at 193.144.1.112","Contact:sip:daemon at 8.8.8.8"]}');

I get;

ERROR: jsonrpc-s [jsonrpc-s_mod.c:1129]: jsonrpc_exec_ex(): invalid json doc [[{"jsonrpc":"2.0","method":"mi","params": ["t_uac_dlg", "INFO", "sip:3003 at 193.144.1.112",.,.,"From:sip:1234 at 8.8.8.8","To:sip:3003 at 193.144.1.112","Contact:sip:daemon at 8.8.8.8"]}]]

Can you give me some clues on how to input the params as its not clear to me from kamailio or json rpc docs.

Many thanks

Jon

Hello,

if you want to run an MI command over RPC, you have to use 'mi' as the rpc command and the MI command as the first parameter, followed by the rest of the parameters for the command.

Cheers,
Daniel

Hi Daniel,

Also I am trying to fire that command using jsonrpc_exec and I keep getting;

jsonrpc_exec_ex(): method callback not found [t_uac_dlg]

I have tried with t.uac_dlg and get the same response, can you let me know if this command is support with this module on 4.3 please and if so what am I doing wrong with the syntax?

Thanks

Jon

Hi Daniel,

Thanks for the response, sorry I must of missed this!

I was thinking of using the t_uac_dlg command to generate the INFO message, but will this allow me to do it within an established INVITE dialog?

I am just worried that changing the CSEQ value will cause issues, so am I better looking to modify in a B2BUA rather than the proxy, or will the dialog module handle this?

Thanks

Jon

Hello,
uac_req_send() is able to send only initial requests (with follow up on auth challenge). It doesn't expose the ability to send requests within a dialog -- the functions exist in c (tm module), but not availble in config.
On the other hand, there should be a mi/rpc command exported by tm module that allows that -- it may be possible to do it from config file via jsonrpc-s module.
Cheers,
Daniel

Hi Guys,

Is it still the case that when using uac_req_send, you cant send withing a specific dialog?

I can modify call-id, but I presume tags may be more of a problem?

See old post below from 2015;

sending a new request inside a dialog is not possible with
uac_req_send(). It is not easy over all because you change the sequence
order (CSeq value). Practically, you need to track how many requests you
sent from the middle to update (and restore in reply) when caller or
callee sends a new request.

dialog module can track changes in CSeq for requests sent to callee,
being used now for authentication of INVITE to another provider, when
Kamailio adds the credentials. But for more you would need to extend the
dialog module.

I just need to send a SIP info within an established dialog to stop some function up stream, so wondered if this is still a blocker?

Many thanks

Jon
