Hello,
I doubt Kamailio adds any sdp body. Can you post here the ngrep with all
the SIP signaling from the first INVITE?
Cheers,

Ok, I compiled the latest rtpproxy.so, the
problem persists: the
interesting facts are: the callee only answers with sdp port once, in
the session progress message. the 200 ok does not have sdp body, but
kamailio inserts sdp into it.
With the new rtpproxy.so kamailio responds to the session progress by
sending a prack to the callee itself followed by a 200 ok to the
caller that includes sdp but has CSeq: 893961 PRACK which never got
requested by the caller though.

can you try with latest branch 4.0? The issue was probably due to
rtpproxy_manage() function not taking in consideration PRACKs with
sdp.
Alternative is to use rtpproxy_offer()/rtpproxy_answer() to control
rtpproxy application.
