asterisk users - Dec 2004 - Problems with Budgestream and g729 codec

Hello.

I'm having this problem with a Budgestream phone: I've correctly 
installed G729 licensed codec in my asterisk box, but when I set my 
budgestream to use only g729 codec, asterisk throws this message:

*CLI> Dec 21 18:02:49 WARNING[2375]: chan_sip.c:2764 process_sdp: No 
compatible codecs!
Dec 21 18:02:50 NOTICE[2375]: chan_sip.c:7295 handle_request: Unable to 
create/find channel

I've seen other threads about the same problem, and I've also send 
replies. I post it here so that as many people as possible reads it. It 
seems to be a very common and unsolved problem.

Thanks in advance,

RODOLFO
