Sorry for the blank response - before...

I use IAX and have a license for G729 at my end and OZTell, my provider, use
G729 as their main codec.
 
My box rejects connections from my provider due to incompatible codecs and
vice versa.
 
I'm waiting for them to get back to me on this.
 
Clint.

What codec are you using on the client and the server? From my
understanding, you have to have a license for both ends of the G.729 call.
Are you passing this through one server to another and the call is being
rejected at the server level?

Hi All,

I get the following when trying to dial in to my asterisk box.

Oct 22 13:58:11 WARNING[3599]: Don't know any of 0xf800 formats
Oct 22 13:58:11 ERROR[3599]: No best format in 0xf800???
Oct 22 13:58:11 NOTICE[3599]: Rejected connect attempt from 203.98.83.19, 
requested/capability 0x200/0xfe00 incompatible  with our capability 0xf900.

and I get the following when I try to dial out.

Oct 22 14:06:31 WARNING[3599]: Call rejected by 203.98.83.19: Unable to 
negotiate codec

I'm using a brand new g729 codec from Digium.

Any ideas on what my problem might be?

Cheers,

Clint
