Hello Because the SER box sits in the middle between the user agents and Asterisk, it will block rtp streams to/from Asterisk. You will need to do either port forwarding or proxying of the rtp streams to enable sound in your setup. This will require you to adjust your firewall settings or use mediaproxy/rtpproxy or both these things even.

Googling I only find configurations relative to the ser machine also being natted, can someone tell me what I need to do in my particular case ? _______________________________________________ Serusers mailing list serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers
