We had a similar problem with a UA that discovers it own public IP and puts that into the Contact header instead of the pvt IP.

Make sure you disable STUN and any other public IP discovery such as ICE in the UA otherwise mediaproxy module does not know it is behind NAT.

Hi all,

    I've got some problems with the MediaProxy.

    I found a UAC with a Public IP that reaches my SIP Server through a NAT. Then the MediaProxy receives the RTP flow from the NAT's IP address, and relay the same flow to the real UAC's IP address (that is public too).

    What about the RTP flow sent by the other party? MediaProxy just ignores it.

    Anybody knows why is the MediaProxy acting that way?

    Thanks in advance,

Víctor
