Hi, I've finally given up on trying to fax over my Digium TDM400 card. I've found that fax over VoIP is quite more reliable (at least I can receive the faxes). My ITSP supports G729 and alaw/ulaw. As I won't be receiving faxes everyday (just ocasionally), i pretend on using g729, unless a fax is detected. Is there any way to force asterisk to make a reinvite, and swap the codec on the fly? Something like this would be great: exten => fax,1,CodecChange(ulaw) exten => fax,2,rxfax(blablabla) Thanks, Juli?n J. M.

I am pretty sure this has been discussed multiple times and there is currently no way to change the codec once the call is established.
