Hi all,

I have an internal echo problem on my LAN only. I replaced the LAN 
switch with a new linksys 2024 with QOS and seemed to help but not fix 
the problem. Any ideas? Here in my setup - Dell PE6400 Dual 700, 
Asterisk 1.2.24/FreePBX, 2-NIC cards, one with a public ip and one with 
an internal ip, one PAP2, one SPA3102 and 2 BT101. I know that bt's are 
cheap that are known for echo problem in the handset. I have one remote 
user that never has a problem. I have a remote test server at home 
connect via IAX with no problems, also a PAP2 with no problem. External 
faxing from the rest of the world via our voip provider is working 
great. One strange thing that I noticed is that we can not fax to our 
iaxmodem, ATA ---> iaxmodem, but works perfect ATA ---> rx_fax. Not sure 
why either.

Jonn
