Hi,
I'm working on a setup, where I have to support late SDP. It is working right now, but I have to use an explicit rtpproxy_offer() when processing the reply to an INVITE without SDP.
Is there a way to have rtpproxy_manage() handle those calls automatically? I was thinking of setting a flag in the request which is used by the rtpproxy_manage() function later.
Best Regards, Sebastian

According to the rtpengine module documentation for rtpproxy_manage(), that's exactly what rtpproxy_manage() does:
http://kamailio.org/docs/modules/4.2.x/modules/rtpengine.html#rtpengine.f.rt...
i.e.
- If INVITE with SDP, then do rtpengine_offer() - If INVITE with SDP, when the tm module is loaded, mark transaction with internal flag FL_SDP_BODY to know that the 1xx and 2xx are for rtpengine_answer() - If ACK with SDP, then do rtpengine_answer() - If reply with SDP to INVITE having code 1xx and 2xx, then do rtpengine_answer() if the request had SDP or tm is not loaded, otherwise do rtpengine_offer()

rtpengine_answer() if the request had SDP or tm is not loaded, otherwise do rtpengine_offer()
What I'm missing there is how to handle an INVITE without SDP. Does that mean, that if we haven't called rtpproxy_manage() on the INVITE, the 1xx or 2xx reply will trigger an rtpproxy_offer instead of rtpproxy_answer?

That's what's supposed to happen, yes.
