Summary:                    faxing with T.38 fails
Description: 
I have asterisk 1.4.26.1 setup with T.38 passthrough. I have linksys 2102
ATA and my provider use Cisco gateway with T.38 support enabled. Everytime
I send fax this fail with no apparent reason. 
In sip debug logs it looks that T.38 negotiation was successfull, later I
receive SIP BYE packet from provider and the call si hangup but no fax is
sent.

---------------------------------------------------------------------- 
There is no indication that Asterisk caused any problem here; the T.38
reINVITE from the provider was properly passed through to your ATA device,
which responded appropriately and the response was passed back to the
provider. Everything looks normal, and then the provider hangs up the
call.

I'd suggest talking to your provider about why their end hung up the call
before assuming Asterisk was involved in causing that to happen.
