[OpenSIPS-Users] RTP Port missmatch

[Manuel Tausendfreund]

Hi ,

i have Playback part on my SBC (3.4.11 Opensips from The Debian Repo) rtpengine is 13.4.0.0


	ua_session_server_init($var(key_ini), "t$var(time)arhb");
	rtpengine_offer("in-iface=$var(interface) out-iface=$var(interface) ",$var(rtp_con),$var(sdp_data));
	ua_session_reply($var(key_ini), "INVITE", 200, "OK", $var(sdp_data));
	rtpengine_play_media("file=/net/audio/sound.wav from-tag=$ft ",$var(time),$var(rtp_con)); 

it works BUT when the other RTP Engine has a Strict Source active it is not working anymore.

Opensips sends in the "200 OK" of the SDP part from the Port from The UA-Agent instead off the port from the Caller

But the Sound is send from port of the Caller

How can I Change this behavior ?

Here look in my Log´s
