<div>We are using RTPProxy as media proxy. When doing a SIPcall

<div>I tried calling sdp_print("1") using module sdpops just
after calling rtpproxy_offer or rtpproxy_answer in kamailio

<div>However the sdp we print just after calling that is still

<div>What are we doing wrong? Any hint how we can get the

if you do the rtpproxy function in core reply_route{} block, then
you can use msg_apply_changes().<br>
<br>
Alternative could be enabling the onsend_route for replies and
looking there inside the $snd(buf).<br>
