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.

You can trap the 415 response from the called peer and send the call through asterisk to get transcoding.

    Hi all,

    I have a scenario with OpenSIPS 1.8 and Asterisks 1.4.   Proxy SIP
    has two ways to manage a call, the first is B2BUA and second is be
    relay between UAC and Asterisk.

    I have a problem, when OpenSIPS works as B2BUA and both UAC can't
    negotiate codec then this call failed. I would like restart this
    same call at second way (with Asterisk). Is that possible?

    Thanks.
    Regards.
