[Asterisk-Users] Specifying a codec to be used in /etc/sip.conf

[Peter Bittner]

Hi all!

Is it possible to tell * to allow connecting an incoming (SIP-) call with the 
G711 codec (a simple fax). I have not found any setting in sip.conf that 
would refer to this problem.

I am using * and the spandsp library to receive faxes from a SIP gateway. 
Everything works for now except the final transmission of the fax. It seems 
that the sender and *, the receiver, do not negotiate the correct codec, 
which must definitely be G711.

Any ideas?
Peter
