[Asterisk-Users] Frustrated with echo...

[Lorentz Hinrichsen]

at the risk of starting a flame war:

I stand corrected on the pricing, however I also stand behind my observation
about the reliability/quality/longevity of the board.  Unless the Digium
folks have made changes to the latest revisions.  I currently have three
TDM400P's all have shown unreliable results.

Symptoms - adjusting the gain would not eliminate echo on local calls,
modules fail and the machine needs to be rebooted

The module failures are the most troubling, this is in a variety of
motherboards and systems.  Intel and VIA based.

If anyone is interested in purchasing my 3 - TDM's (I have a variety of
modules, primarly FXO) They are for sale :-)

I also should state that I've only been using the Sangoma's for a little
over a month, I did purchase the Echo Cancelling model (which prices it
higher than the TDM400P).  But I've had no trouble with echo so far.
