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.

(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?Vinícius Fontes www.asteriskforum.com.br - Informações e discussão sobre Asterisk e telefonia IP ----- "Jason Baker" <jba...@glastender.com> escreveu: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.

The system below is out of Livonia, with an AT&T PRI as well.
