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.r…
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()

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.
