[OpenSIPS-Users] Info about rtpproxy and opensips working together on different hosts...

[Bogdan-Andrei Iancu]

Hi Roberto,

I checked the RTPproxy code and the only case where you get the 
"ERR:handle_command: can't create listener " error without any previous 
error is for cases:
    - the system user you are running rtpproxy as, does not have 
permission to bind on the listening IP (- l option in rtpproxy)
    - you already have another application (like Asterisk) already using 
the same listening IP and port range as configured in RTPProxy.

Regards,
Bogdan
