Not to mention cheaper.


I never really considered one. I've never used one for that matter. This system is really only a testbed. If it works out, then in 6 months to a year we'll put asterisk in main site and all the phones in this location will slave off that system.

But, I went to atacomm.com and tried to spec out a channel bank solution:

Rhino Chasis: $750
2 4port FXO cards: $599
TE110P: $499
Echo canceler: ????
Total: $1848

A TDP2400 8 FXO with echo can module: $1093

Mine didn't come out cheaper, what kind of equipment do you recommend?

Thanks for the suggestions.

If it's a testbed system, why not do a little research on eBay and get the good stuff?

Digium or Sangoma 2-port T-1/E-1 card ~1,000

Some things I've gotten from eBay:
  Adtran TA750, FXO, FXS, Power, Battery ~$300
  Tellabs EC Chassis ~$50
  Tellabs EC cards, if they didn't come with the chassis ~$30
  Power for Tellabs ~$30
