[Asterisk-Users] TE410P on Dell 2650

[Aza]

I have a problem with a Dell 1850 and a TE410P card as do a few others who
posted over the weekend.

The problem in this case isn't so much echo but static and chop on all calls
using ZAP channels. My zttest results look pretty much the same as yours. We
were thinking it was the RAID controller but someone posted that they had
the same problem with an 1850 without the RAID controller. 

We've got some E100P cards we're going to try out but it's difficult to
troubleshoot this issue when it involves live PRIs.

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

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.
