asterisk users - Jan 2009 - Has anyone used FaxGateway()

Hi,
I've been trying to use the FaxGateway application to send T.38 out
over Zaptel using asterisk but I don't seem to be having any luck.
I'm executing it in the dialplan like: FaxGateway(Zap/g0/[number])

Has anyone had any luck using this thing and can enlighten me on how
it's supposed to be used?

Thanks.

Well, T.38 works over IP, not TDM...

Hi,
Here's part of the log that I see.
In this case I'm testing on a box that unfortunately doesn't have a
PRI connection.
I've so far tested with just voice calls so far, but as you can see,
FaxGateway can't even dial out to the SIP trunk properly.

Here's also what the dialplan looks like:

exten => _1NXXNXXXXXX,1(faxtest),FaxGateway(SIP/vitel-outbound/${EXTEN},-1)

And the log:
