Yes. We are using it on a PRI. List on a the cards was like $2000 US each and like $1000 US and $2000 US for the 2 and 4 port chassis itself, respectively. So roughly $5000 for a fully populated 2 port and $10000 for a 4 port. We're still using a loaner from our provider to test out so we haven't gotten an actual quote yet. We are, however, hoping for the actual price to be a good bit lower than that.

Do these work with PRI's as well?  What's a ball park price on these?

Thanks, Billy

Well, first off we're not using them directly off the asterisk. Our
Asterisk runs into our Alcatel OmniPCX 4400 and then to the PRI. We have
about 70 or so IP phones off the 4400 and just a few off the Asterisk box
(so far) and of those probably 10 to 15 (alcatel) users complain
consistently about the echo. We've only put it on one of our spans to
start
with and I directed the most complaining users to it. So far the feedback
has been very good.


I use an IP phone every day and I rarely notice it, but I may have just
learned to tune it out. :) But having said that I have noticed that even
that occasional echoing call that I was getting seems to have gone away.

Ditech Communications ( http://www.ditechcom.com/ ) has a 2 slot and a
4
slot chassis and you can populate them with just 1 echo cancelling
card if
you like.

They have RJ45 jacks and you have to use a T1 Cross cable on both
sides.

Hi Robb,

Thanks for your reply. Have you found that the Echo Can's from Ditech
take care of your echo? Do you experience echo on any calls (e.g. 1 out
of 300 calls, 1 out of 500..?) Thanks a lot for your advice on this. I
will give them a call. Additionally, what is a ball park range on
pricing?


Thanks in advance!

- Brent
