[Asterisk-Users] Channel Banks

[Greg Scasny]

Do not buy an adtran - no auto impedance match on FXO ports (echo, echo,
echo) and no call disconnect supervision on FXO ports.

Get the ADIT 600 (CAC) (also called a Cactus Lite), they have all those
features and have a 48 port capability, plus callerid works wonderful.

If you still want an adtran, I have 3 I can sell you for cheap :)

Subject: [Asterisk-Users] Channel Banks

We have an Asterisk Server with 5 X100's and a 4-port openline card we
have been using for 6 months.

My only complaint is echo.  Some lines sound good, others echo all the
time, some echo intermittantly or only when conferencing.  I
have tweeked the tx/rx gains and played with echo timing as much as
possible.  It is time to go to a channel bank (a PRI is still
about $200/month more than POT's lines) .

It appears the favorite channel banks are CAC and adtran.  Am I missing
anyone?  Does one make or model perform better echo
cancallation then the others?  Are some channel banks still having
problems with caller-id?
