asterisk users - Nov 2003 - Pbx / channel bank install

Hi all,

We are about to make our first channel bank install. This will be a one
PRI outside connection and up to 70 extensions. 

As the schedule (and the budget) is pretty tight, I would like to learn
a little bit more about general experiences with channel banks, like
echo cancellation problems, Caller ID usage, etc.

TIA,

Paulohm

I recommend using Adtran 750's. You can get them setup with all your FXS
ports on Ebay for around $ 500.00 used but in great shape!  These work great
out of the box.  If your only using 70 extensions you will need 3 of these
unit's.  In our setup we have 4 Adtran 750's one 600 and incoming PRI
and
outgoing T1 for long distance!  We do with on one server with two T400p
cards.  We have faxes, Modems and lots of phones attached to them.
