I'm trying put kamailio in front of asterisk server farm. Fow now, 2 asterisk servers are running and i'm trying to make some basic calls between two UACc.

All asterisk servers has been ofuscaded from public internet using 10.189.122.0/24 network.

All trafic must be passed throught asterisk so RTPproxy is used to (and used for rtp bridging).

Kamailio and rtpproxy is running with public IP address, and private ip address (mhomed=1)

But a wired thing append on my SDP body: c line have two rtpproxy public addresses concatenate (see my capture attached).

Any reason for this ? Only invite method from my asterisk contains 2 publics IP addresses concatenated.

Does it mean than rtp_manage as been executed twice ?

Thanks in advance.

Regards.
