Re: [hylafax-users] Analog DID Questions

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.

You are correct. I confirmed today that Verizon's analog PBX trunk with 20 DID's would be receive only.

What exactly would I be asking my Telco for, as far as service, if I were to go the DTMF route? Are there any pro's or con's for DID vs DTMF other than the cost of hardware? IE, some functionality, etc.
