Hello, Here is a breakdown of the issue I am experiencing. I have three remote employees, in various states, who have Polycom 501 phones. They are unable to receive incoming calls after a few minutes of the phones being plugged in. They work immediately after being plugged in, but they lose the ability shortly thereafter. They can always make outbound calls, but only to real phone numbers, not extensions.
They each have NAT routers, and I have triple checked that they have opened/forwarded the correct ports, basically 5060-30000 UDP. Once they plug the phone it (power and ethernet) I see on the CLI console of the asterisk server that the phones register: Asterisk CVS-v1-0-12/01/04-18:46:01, Copyright (C) 1999-2004 Digium.

I am curious what I am missing. Thanks.
