<br>
I receive an INVITE from a NAT'ed client, which I forward to a second proxy after calling use_media_proxy.<br>
The second proxy send the INVITE upstream.<br>
Upstream starts sending RTP (to media-relay), then rejects the call.<br>
I try next gateway (on second proxy), which answers 100, 183 and later 200 OK. (And sends RTP to media-relay)<br>
<br>
Unfortunately the relay received 7 RTP packages from the failed attempt, and therefore RTP from succesfull call is ignored.<br>
<br>
As I know the IP range is non- NAT'ed, I would like to ignore the RTP from the first gateway, by forcing relay to use SDP.<br>
Is it posible to tell the relay "This client is not NAT'ed, use IP address/port from SDP"?<br>
Or<br>
Don't forward RTP before SDP. (That way, RTP from failed call would be ignored)<br>
<br>
