[asterisk-users] Asterisk to asterisk t.38

Make sure that the trunk you have between the two servers has the t.38 
enabled on it. Do you have any NAT between the two servers or are they on 
the same lan. We do the t.38 faxing between 1.4 and 1.6 asterisk boxes all 
of the time. Our audio codes gateway dumps into a 1.4 box and all faxes 
calls are then sent to either 1.6.x or 1.8.x boxes and then on to the final 
ata.

Thanks

Hi,
I have an Audio code gateway between two asterisk servers. The 
audio code has PRI connected for PSTN. I can send faxes and receive 
faxes in ast 1.4 . Also I can send faxes for ast 1.6 to outside (PSTN) 
and receive faxes. The only problem I am having is sending/receiving 
between ast 1.4 and ast 1.6.

ATA (T.38 capable) > AST 1.6 >>>>>>>>>>AUDIO CODE>>>>>>>>>>AST 
1.4>>>>>>ATA (t.38 Capable)

Thank You
Amit Nepal
