[OpenSIPS-Users] UPDATE (SDP) modification

I could do the rtpproxy offer on main route but the rtpproxy answer is not working on the onreply_route:
      if (has_body("application/sdp")) {
           rtpproxy_answer("rocf");
      }

On which route should I use this rtpproxy_answer for the 200 OK (SDP) reply to the UPDATE message?
200 OK (SDP) reply rtpproxy works fine for the INVITE (SDP).

Cheers,
Bela

How do I force the UPDATE to go through rtpproxy offer/answer?

If UPDATE goes through rtpproxy offer/answer it gets modified automatically too.

if you call rtpproxy offer and answer, SDP is automatically modified.

Hello,

Is there any way to modify the UPDATE (SDP) content, i.e.
c=IN IP4 aaa.xx.yyy.zzz

The callee is sending this message from the PSTN network and I need to use rtpproxy. Without the UPDATE(SDP) modification the call is one way speech/mute.

Cheers,
Bela
