Re: [Asterisk-Users] Remote employees using Polycom 501 lose ability to receive incoming calls after few minutes.
Sounds like the registration interval in the phones is less than the required registration interval of the server. I had this occur when using a SIP phone with an ITSP.

FYI, when we had NAT routers at both locations setting qualify=yes did not work.

Re: [Asterisk-Users] Remote employees using Polycom 501 lose ability to receive incoming calls after few minutes.
You have to lower the registration interval in the phones to under a minute otherwise the NAT hole closes and no calls come in. Polycom has said that they are going to be putting in a keep alive in the firmware at some point.

[Asterisk-Users] Remote employees using Polycom 501 lose ability to receive incoming calls after few minutes.
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 5060-3 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.
