[OpenSIPS-Users] Media Proxy 2.3.4 bug?

[Mauro Davì]

Hi All,

I have this scenario:

An user1, connected trought an UA1 (behind NAT), make a sip call to an 
user2.

user2 is logged into the system on 2 UAs (one behind a NAT and the other 
on a public IP Address).
                              
user1 sent an INVITE message to the SIPProxy (SP) in wich there is an 
SDP with 16442 RTP Audio Stream port

SP sent the INVITE to the 2 UAs in wich there in an SDP with 30506 RTP 
Audio Stream port

The second UA sent to the SP a 200 OK with 10808 RTP Audio Stream port

The SP sent to user1 a 200 OK with 30508 RTP Audio Stream port

There is a problem, the media proxy sent the RTP Audio Proxy to the 
second UA from the source port 30510 (and not from 30506), the 
destination client is behind a NAT and the RTP Audio Stream isn't 
established.

I'm in a multi-proxy environment. I can provide the wireshark trace.

Do you have any suggestions? There is already a bug fix for this problem?

Thanks in advance
