[Asterisk-Dev] IAX2 no compatible codecs

[Jason Penton]

Hi All

I have a strange problem using IAX2. When placing a call to my IAX clients
(firefly) via the Asterisk dialplan all works great. However trying to
initiate a call via the manager interface to the IAX client using the
following command results in an error:

Action: Originate
Channel: IAX2/7000
Extension: 7000
Context: local
Priority: 1
ActionID: 1

The error I get in the CLI is "Jun 17 08:18:36 WARNING[180236]:
chan_iax2.c:4534 socket_read: Call rejected by #IP: No compatible Codecs"

Does anyone have any ideas.

Thanks in advance 
Jason
