[Asterisk-Users] Polycom 501 horrible echo

[Jerry Jones]

I have many Poly installations and have not had this issue, EXCEPT -  
the one time we permitted a customer to run their computer data  
through the telephones.

We also have noticed a poor server config can cause this in testing.

Noticed when I had one person building * servers using Debian. Had  
them rebuilt with FC4 and have no issues - yet:)
