[OpenSIPS-Users] Nathelper / rtpproxy , problem with trusted IP

[Laurent Schweizer]

Hello all,

 

Small problem with rtpproxy and nathelper

 

as you can see in the log bellow , I use the force_rtp_proxy method  with
the 'r' flag to indicate to trust the IP of the SDP.

 

In the example bellow, the trusted IP is "95.128.80.6 3966" , the problem is
that the old rtp source (in this case a MoH server) continue to send 1 or 2
packet so the RTP proxy change them with "95.128.80.92:1086" so packet are
not correctly forwarded.

 

If the IP must be trusted why he take care of a received Packet ?  

 

I use the rtpproxy 1.2.1.

 

Regards

 

Laurent
