I am using a digium TE110P and a TDM04b (or whatever the one with 4 FXS

faxing with a cheap fax machine, though the asterisk box almost never
goes above 5% CPU usage unless there are some conference calls going on.
I can run modems/faxes just fine (though the modem connections seem to
have a bit more latency than through a POTS line, it is acceptable for
our use.)
Just be sure to set echocancelwhenbridged=no and tweak your txgain and
rxgain on the line (this is not a do it once and you're done thing, I
had to go back probably 5 times over the course of 2 weeks to get the
right numbers.) I am even doing a redirect to eFax (I'd do with asterisk
but we already had an efax account and it works well enough) on one of
my DIDs and it works great.
Quite honestly I found a lot of documentation on how faxing in Asterisk
is hard, and I just never saw that. Maybe I got lucky with a magic
combination of hardware and forgiving fax machine, but it kind of just
worked the first time I tried it. Now, if only setting up a 'page all'
function on Cisco 79XX SIP phones without using a line appearance was so
easy...

Anybody had similar problems or success stories with sangoma cards?
Running zttest on my box with both a TDM04b and A200D installed
indicates and average of 99.96% for both. Not sure how accurate that
might be as the A200D card appears as a 24 channel interface in terms of
/dev/zap even though only four ports are equipped.
The TDM04b won't support faxes on this box under any circumstances and
I've played around with about every possible pci latency, etc, change
that folks have suggested in the last two years.
Based on my heavily invested testing to date (which includes about two
years of doing this), the "only" usable fax support thus far comes from
using the A200D card with the fax machine directly connected to a fxs
port on that card, and an fxo (pstn) port on the exact same card. Those
fax tests have been 100% solid using a cheap/older Brother fax machine.

Some people have problems, some people don't. There is no way you can be
prepared for every situation out there. We try our best.
