Hi,
I would be interested in any reports of anyone getting a T.38
FAX to
send or receive successfully with Zoiper. I've tried to test
my T.38
implementation against more than one revision of Zoiper, and I
yet to
see it behave sanely.
I could receive yesterday from Zoiper 2.18 Windows free edition
with ReceiveFAX installed with latest Asterisk 1.6.X.
Would you like more details ?
To be more precise, I only tried once and I wouldn't swear T.38 mode
was used (I've checked) : maybe ReceiveFax would allow G711 inbound faxes.

The option is t38pt_udptl = yes, and has to be set in both the global
part and in the peer. The option was t38pt_udptl in 1.4 and I don't
think it got changed in 1.6.

with some packet captures, we should be able to diagnose the issue
