[Asterisk-Users] Using as FAX 100% IP

[Steven Kokinos]

I don't believe this will work, but haven't tried myself. TAFM requires 
spandsp. I'd do some investigation there as to whether spandsp can 
function with g711 (the last i checked it didn't).

Good luck - if you make any progress please post to the list.
