I have never used T1 cards but as far as POTS line cards I would say that I like sangoma better. It is a little bit harder to set up but works wonders. ----- Original Message ----- From: "Thomas Kenyon" <[EMAIL PROTECTED]> To: "Asterisk Users Mailing List - Non-Commercial Discussion" <asterisk-users@lists.digium.com>

Anyone using the echo cancelation cards from digium?  We are using the
single span T1 card with out  echo cancel and I was curious if it was
worth the money.

I'm running Asterisk 1.0.11 with few Sipura 3000/2000 units and have no
echo whatsoever. I just tried new Asterisk 1.2.12.1 and the first thing I've noticed was
terrible echo, not to mentioned that it keep crashing constantly to a
point this that is not possible to use it.
I've got an SPA-3000 at home that is constantly crashing, echoey and is almost unusable. (The CS4660-based ATA and PA1688-based handsets have otherwise been fine, as were the the Cisco 468 and Linysys PAP2 when they were in use).
