Thanks Lonnie. Good call. That will be my next test.
PS IP Address stays the same.

Michael,
My theory has always been your problem is with an upstream firewall.
Stopping asterisk for a period of time may allow upstream firewall states
to expire.
By rebooting AstLinux you will do the same (stop/start Asterisk) and if you
have PPPoE you may pull a different IP address which will bypass any upstream
states.
From all you have described, this looks to me to be an upstream issue
relative to AstLinux.
