[asterisk-users] T.38 gateway ATA

[Bryant Zimmerman]

Jeff

Can you please clarify your layout? If you have an asterisk 1.8 (I would 
use 10 for this if possible) server why can't you just take the gateway 
call on that via a sip trunk. If you are coming in from and land line and 
want to do t.38 to the asterisk 1.8 server you would need a FXO t.38 
gateway. Based on your description I am not sure what your sources are and 
what your final desired destination is. Please be specific with your 
response.  We do t.38 all the time and have great success with it but the 
success is in the setup and control of the endpoints (gateways and ATAs)

Thanks

Subject: [asterisk-users] T.38 gateway ATA

Hoping for some clarification. I would like to setup a NORMAL (not 
T.38) fax machine on an ATA, and have the ATA be a T.38 gateway to a 
remote asterisk (1.8) server, which is doing T.38 relay (passthru) to a 
provider.

Some amount of googling today seems to imply that most ATAs are just 
T.38 passthru devices, and expect a T.38 capable fax machine, otherwise 
just fallback to ulaw (and mostly fail, in my experience so far).

So does anyone use an ATA that actually does the gateway transcoding to 
a normal fax machine? Or am I barking up the wrong tree?

Thanks!
