asterisk users - Jun 2011 - ReceiveFax to G.711

Hello,

While using FFA, how can we program a specific extensions.conf script to
accept the fax in G.711, while for other calls (from a different source), to
allow T.38 with or without fallback?

The current ReceiveFax(filename,f) is not working for us with one of our
providers.

Thanks,

Michael

You can't control this in the dialplan. You control this by disabling 
T.38 support in sip.conf for that provider (setting 't38pt_updtl' to 
'no'). However, don't expect very high reliability transferring FAX
over
G.711 over the Internet.

Alternatively, if your provider claims to support T.38, then ensure you 
are running an updated version of Asterisk, and if you still can't make 
FAX work over T.38 with them, post debug logs here and we can try to 
help you figure why it's not working.
