[asterisk-dev] T.38 Issues

[Bryant Zimmerman]

Our T.38 stopped working on Monday. 

Our system is setup with a PRI gatway to an asterisk 1.6.1.18 server to the 
ATA 

We are using NAT between the Asterisk switch and the ATA units 

When I do packet captures at the server I see both legs of the call (Server 
to Gateway) and (Server to ATA)
The inital T.38 signialling seems to be working but the T.38 UDP from the
gateway to the server is not being sent from the server to ATA. 

This was working on Sunday as 10 faxes went out with no issue.
Nothing was changed on the asterisk server and I have restart the asterisk 
process 

Any ideas why asterisk would not be forwarding the T.38 UDP packets to the 
end point.
At first I thought it might be a Nat issue but they are not even being sent 
from the server? 

Any advice on how to further trouble shoot this one? 

Thanks
Bryant
