Re: [hylafax-users] Analog DID Questions

[John Warren <jwarren@xxxxxxxxxxxxx>]

You can also look at getting a T1 line but there are issues with  
that. First T1 modems cost an arm and a leg and then some. Personally  
I think that T1 modem cards are way over priced. I think the last  
time I checked a 24 modem port fax T1 card was well over $7,000.

What we have been looking at is a T1 line feeding a Adtran Atlas. The  
Atlas is a great little box. It will take multiple T1 cards set to  
either be either end of the T. It will also take FXS and FSO analog  
cards which can do DTMF DID + CalledID and still connect to a  
standard modem. What we're looking to do is share a T1 with our PBX  
with the Atlas in the middle. It will look at each incoming call,  
check the DID, send it to either the PBX via T1 or Modem bank via  
analog. Our cost will be around $3,000 to $3,500. Not too bad for  
what we're getting.

You might want to take a look at it.
