[Asterisk-Users] X100P Echo - not resolved

[Rich Adamson]

I still have echo during the first 15 seconds (or so) of each call, and
the exact same thing is happening with either of two X100P in the same
2.2ghz system.

asterisk# cat /proc/interrupts
           CPU0

asterisk# grep wcfxo /proc/interrupts; sleep 10; grep wcfxo /proc/interrupts

asterisk# 

The system has nothing connected to the usb ports, and the only ethernet
is the eth0 shared with wcfxo #1.  Executing the above while inititating an 
outbound call (c7960 -> * -> x100p) indicates one x100p card (Int 9) is 
running about 1228 interrupts per second, while the second x100p (Int 11) 
is running about 1001 per sec. Echo sounds identical on either x100p line.

In zapata.conf, both x100p's include...
echocancel=yes           
echocancelwhenbridged=yes                                                       
rxgain=0.0 
txgain=0.0 

Is this likely a motherboard problem too?  Or, is there some other indicator
that I should be looking at to narrow down the issue? It really is very
disturbing on both incoming and outgoing calls.
