[Asterisk-Users] TE410P on Dell 2650

[Charlie Watts]

I have a Poweredge 2650 w/ a TE410P card. I'm getting lots of local echo
(my users hear themselves) when calling local telephone numbers.

Echo cancelling helps, but doesn't solve the problem.

>From zapata.conf:
echocancel = 64
echocancelwhenbridged = yes
echotraining = 800

My zttest results consistently look like this. The digium fellow who has
been helping me says these are lower than he'd like to see.

[root at voip zaptel]# ./zttest -v
Opened pseudo zap interface, measuring accuracy...

8192 samples in 8193 sample intervals 99.987793% 
8192 samples in 8192 sample intervals 100.000000%

Best: 100.000000 -- Worst: 99.987793 -- Average: 99.989149

The card isn't sharing interrupts, etc. We're at the point where the
Digium fellow is suggesting other motherboards and avoiding SCSI.

Anybody else have a 2650 with a TE410P ?
Do you have any local echo problems?
What do your zttest results look like?
Are you satisfied with the system?

Thank you very much.
