asterisk users - Jan 2006 - suddenly iax calls don't work anymore

Hi,

Asterisk is new for me. I had a working configuration, but suddenly I can't
call anymore
with my voip provider. I am not aware that I changed anything in the
configuration, but
who knows. Can somebody explain me what is happening here? I changed username,
password and number.

Looks like your end is offering g729 as a supported encoding format,
and the other end is choosing it, but your system doesn't actually have
the G.729 codec.

In iax.conf, you can either add "disallow=g729", or probably even
better,
put "disallow=all" and then specific allow lines for the codecs you
want
to support, such as alaw, gsm and so on.

Don't forget a reload in order to act upon the changes.

Cheers
Tony

Someone will probably correct me, but it looks like you are trying to 
use the g729 codec for your calls (or coco-connect.de is forcing you to 
use g729), but this requires a license from Digium and is not installed 
on your machine.

Try using a different codec if possible or, if you do have a g729 
license try re-installing the codec and re-activating it.

I think this may solve the problem. But as I say, someone may correct me 
- I may be completely wrong about this.
