TBCP messages are currently not supported by the PJMedia stack. I had a similar problem where i needed to use TBCP(RTCP APP) msgs for a similar kind of PTT application. So had to hack around by defining my own callbacks at the application level and letting the PJMedia stream layer call it after passing the needed PKT from the transport layer.

The next step for us is to implement TBCP or similar to do this. ? Hopes this helps. ? Cheers / Olle ?

Hello Everyone, I would like to implement PTT using the pjsip stack; how can i do it? I want a software solution so muting/unmuting the mic is not in my options. Thank you.
