asterisk users - Dec 2003 - E400 or TE410 (digium) vs PRI 30M (Eicon)

Hello,

I would like to have some comparison between E1 cards from Digium and 
those from Eicon for a VOIP - ISDN Gateway.

How does they compare on the echo cancel point of view?
Is the echocancellation code for E400 good enough for production 
environment?

Best regards,

Daniel

The code for the Digium E1 is the same as used on any other Digium
interfaces. It is in software and shared across all Zaptel hardware.
There shouldn't be an echo at the E1 interface. The echo will be on
either an analog end or in speaker bleed over to mic. 

Something you will also need to consider, what software will you be
using? Digium cards work with asterisk, and I doubt that the Eicon E1
cards do yet unless they use the capi driver.

I will use Eicon BRI Cards as they have Echo cancel on board.

Yes the Eicom PRI Card is very expensive and that was the reason of my 
question. I am searching a No echo solution and if the E400 meats this 
criteria I will undoubtly order this card when I will have to switch to 
PRI Card.
