[OpenSIPS-Users] Renegotiation

[Bogdan-Andrei Iancu]

Hello Jorge,

You need to use the failure route - 
http://www.opensips.org/Documentation/Script-Routes-1-10#toc3 .

Use the t_on_failure() function (from TM module) to arm a failure route 
before sending the INVITE out (before the t_relay()). The failure route 
will be triggered when receiving the negative reply - use 
t_check_status() 
[http://www.opensips.org/html/docs/modules/1.10.x/tm.html#id294673] to 
check the reply code and if 415, simply change the RURI and send the 
INVITE out again.

Regards,

Bogdan-Andrei Iancu
