asterisk users - Jan 2007 - Requirements for faxes to work properly

Hello, everyone.
I'm reading about the asterisk new features. One is T.38 protocol
support. I used faxes before with asterisk 1.2 and everything was
working quite well. Could anyone explain what have changed in the way
faxes are handled.
Another thing is, in order for asterisk to work over T.38 with my fax
machine do I also need a T.38 support from my ATA and my SIP provider?
Thanks in advance.

The T.38 support in Asterisk 1.4 is only pass through. Asterisk is not
an endpoint or gateway of any sort. It only works passthrough in
SIP to SIP calls without chan_local or chan_agent involved.

Both endpoints of the call will need T.38 support and have T.38
enabled in sip.conf.

Asterisk 1.4 as I see it is still a bit unstable and not ready for
production use. Be careful out there.
