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.

----------------------------------------------------------------------
I've also done wireshark trace. After T.38 negiotiation and switch over you
can see UDPTL packets. But there are only UDPTL packets from ATA to
asterisk. I can't see any packets from asterisk to provider...
