[Asterisk-Users] scandsp, voicetronix and rxfx

[asterisk at capepaterson.com]

Hi all,

Trying to get fax reception going using a voicetronix openline4 card,
however, there are two issues (as far as I can see)

(1) Currently the voicetronix world (cards, firmware, drivers, channel
prog etc.) does not do fax tone detection.  I have spoken to the
voicetronix guys , understand what has to happen there and may do some
hacking if I can resolve the second issue.  Meanwhile, I guess I can do
some sort of manual (or pseudo manual) transfer to a spandsp extension.

(2) More worringly, when I do force a transfer to rxfax, it does not
appear to train with the fax machine that I am using (samsung sf-330). 
Here is a snippet of log:

and this repeats ad nauseum until the fax machine gives up.

Any ideas what the issue might be anyone?  Could this be voicetronix
card-related?

Thanks in advance.
