[Asterisk-Users] Error: Unknown RTP codec 72 received

[Julius Kidubuka]

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 the error, "Unknown RTP codec 72 received".

How can I go about this?

Thanks,
