Summary: Asterisk 1.4.17 T.38 doesn't work
Description:
I had installed Asterisk-1.4.17 on Debian 4.0 (etch) using it since two
months ago.
Recently, I required to do incoming and outgoing fax for SIP client.
I bought Grandstream HT-486 and Kapanga softphone.
I test following scenario:
--------------------------
Xerox fax machine---HT-486----Asterisk-----Kapanga
Xerox fax machine---HT-486----Asterisk-----HT-486---Panasonic fax machine
When I try to send/receive fax on scenario then it fail.
And I got
[Feb 17 11:38:30] WARNING[16454] chan_sip.c: Unsupported SDP media type in
offer: image 5004 udptl t38

Try setting it globally. I have a feeling it will help...
