[Asterisk-Users] RxFax problems

[Darryl Ross]

Hey All,

I'm still (since April) having problems getting RxFax to work over an
ISDN4Linux channel. Just wondering if anyone has had any luck getting it
to work?

I have done a CVS update today (about half hour ago) and made sure I have
the latest version of spandsp according to Steve's website
(spandsp-0.0.1k). When I was compiling asterisk, I got the following
warnings:

==================================================================

Although it continued to compile without any other errors or warnings.
When I try to receive a fax (sent from a Rockwell HCF modem) I get the
following output in the asterisk console, and the originating fax doesn't
handshake with it:

==================================================================

==================================================================

Does anyone have any idea how I can get this to work? At the moment I am
only really interested in receiving faxes, but sending might be nice in
the future.
