Good call, Lee. Unfortunately, we only have a single port Sangoma
card in our asterisk server. In order to do what you suggest, I would
have to buy a dual port card and a channel bank or T1 modem. Thats
more $$$ than is warranted by our fax traffic.
Also, given reports of problems related to frame-slippage and other
weirdness encountered when sending data/fax through Asterisk, I'm
reluctant to invest that money. Have you tried this setup yourself?
Cant iaxmodem work by having asterisk bridge the pri channel as needed
(did based routing perhaps) and then have hylafax use iaxmodem as the
modem it uses. That should result in no additional hardware, which
means testing can happen with little cost to see if it works for you.
As I understand it iaxmodem just acts like a modem, and doesnt
actually
do the processing that hylafax does, so the two would work together
instead of one or the other. I may be wrong on this, but that is the
way it looks to me so far.
This is true, but:
1.) Lee has stated that IAXModem is still "Developer-grade" code.
2.) I don't have a spare PRI for testing, and our phone system is far
too mission critical for me to go mucking about with it and trying
this out (especially given #1, above).
3.) It will not be easy for me to test out this setup without simply
switching our production HylaFAX server to use IAXModem, which I am
again reluctant to do, seeing as it is our production server and we
depend on it. Testing fax service setups is notoriously difficult due
to the huge number of different fax machines, etc that are out there.
