HylaFAX supports most any AT-compatible fax modem.  So the T1 support 
isn't so much a factor of HylaFAX as it is a factor of the "modem" 
itself.  So your options for AT-compatible T1 modems are (as far as I'm 
aware): Patton 2977, Eicon Diva Server, or a Zaptel card.  Unless you 
can find a used Patton 2977 around (and even if you do, the price still 
may go for more than your $600 budget) the only option that suits your 
small budget would be the Zaptel option.

The OpenVOX T1 card should be well-within your budget.  Then it's a 
matter of getting Asterisk and IAXmodem installed and configured... and 
then HylaFAX.  I'd suggest taking the rest of your budget left-over 
after the T1 card purchase and hiring a consultant to log-in and perform 
the Asterisk+IAXmodem+HylaFAX install.  IAXmodem and HylaFAX are 
straight-forward enough that a newbie can get it rather easily.  
Asterisk, on the other hand, is quite a bit of a learning-curve... but 
if you're sharp you may not have a problem with it.

> The clincher is I'm relatively unfamiliar with the names, models, and prices of T1 or ISDN PCI hardware, let alone finding one that works under a modern Linux kernel (2.6.16.xx currently).  I've learned so far of the big fish eating small fish history w/r to Brooktree -- currently owned by Dialogic/Cantata --, but wasn't sure what else is out there.

I'm not a fan of using BrookTrout... and I don't think that it performs 
any better than other less-expensive (and non-proprietary) solutions 
with HylaFAX.

Their engineer said he's heard of setups like that, using Tandem E&M over FXS (Castelle's routing guide mentioned this), but he said their supported method involves using FXO ports instead, hence the equipment changeout we'd need.  In either case, I'm told there's little difference between FXS and FXO, with the latter lacking dial tone and capable of trunking to hand off digits.

I don't know anything about the channel bank hardware you indicated, but 
normally it would work with the FXS ports by signalling DID as DTMF 
after the modem goes off-hook and before patching the call through.

> Asterisk+IAXModem...Asterisk I have heard of, but not IAXModem.  I take it this is software that would interface with the T1 card and hand off the DID/DNIS digits to Hylafax via emulated modems?

Yes.  See:  http://iaxmodem.sourceforge.net.

Thanks,
