I have not really messed with the QoS on my network, I guess that will
be my next step. I am running 1 - 3Com Unified Gigabit Wired and
Wireless PoE Switch and several 3Com Baseline Switch 2924-PWR Plus
Switches. I know these switches support VoIP. I guess I'll have to set
up a VLAN for my phones. I put everything (phones and computers) on the
same LAN, on the same subnet, maybe I need to separate them.<br>

<pre wrap="">Oops sorry, I didn't read you have a VPMADT032 module. (Damn ADD)
Don't bother setting echocancel=256, echocancel=yes should be working fine. Also don't bother with OSLEC. Maybe the IP part of the call is introducing the delay that is being perceived as echo. Do you have QoS set up to minimize latency on the IP side?

<pre wrap="">Well I tried Doug's suggestion and the echo is now better, but when I
call an outside analog line I still get some echo. I can hear my voice
in the ear piece of the phone with a slight delay. Is this just a fact
of life with VoIP, or is there a better way to reduce line echo?
Again, for reference, I am using the VPMADT032 echo cancellation
module attached to a Digium TE121 PCI express card. The incoming phone
service is a PRI.

system below is out
of Livonia, with an AT&T PRI as well. Note the rx/txgain entries, it
may be useful as well:
