Hi all, I have setup two X-Lite phones and an Asterisk box. They are all on the same LAN and have private IP addresses assigned to them. I am able to place a call from either phone but the moment it is picked up (trying to be answered), it goes dead - as in no sound! I get two errors, "Unknown RTP codec 72 received" and "RFC3389 support incomplete." How can I go about this? Thanks, -- Rgds, Julius Kidubuka.
