Hi Warren -

> Questions:
> (1) Good 2xT1 card with hard echo cancellation?

I'm not sure if it has onboard echo can, but Sangoma has a two port
model.  I've never used them (I have a TE410P), but I've always read
very positive things about them, especially on the quality of the echo
can they use.


> (2) Good 4-port analog card?

Digium TDMs have always worked very well for me.

If you have an analog fax machine and you want to use a DID number off
the T1, I would recommend getting a digium FXS card to connect to the
fax machine.  I've used this setup for almost 2 years now, and it's
very effective.

If you want to use a POTS line for fax, just skip asterisk altogether.
 Run the POTS line directly to the fax machine.


> Am I best off using Hylafax?

If you want individual DID fax numbers for employees, or you want to
skip a paper fax machine, use Hylafax (or spandsp).

You'll have to talk to the provider about that.  They can use the
local loop, but beyond that I'm sure it will take some re-provisioning
on their part.
