[OpenSIPS-Users] re-INVITE (Hold) looses audio

[Callum Guy]

Hi Mark,

Can you confirm which engagement functions you are using? Does the SDP look
like its being handled for the RE-INVITE transactions?

I have dealt with some similar scenarios recently and would highly
recommend using the separate rtpproxy_offer() and rtpproxy_answer() methods
over the dialog bound rtpproxy_engage() - this will give you a more
granular control. Generally speaking I would advise that you identity a
loose routed INVITE and check for present of SDP and use this to trigger an
offer, somewhat like this:

if (loose_route() && is_method("INVITE") && has_body("application/sdp")) {
  rtpproxy_offer(OPTS);
}

You'll then need to consider the additional scenarios for last SDP and ACK
processing to handle both the answer and edge cases however hopefully this
will help you move forward in your config.

Good luck,

Callum
