We have Polycom VVX311 phones installed. At certain times they have become unregistered. Our internet connection has been fine and running smoothly. It seems the only solution given was unplugging and replugging the phones; however, it has become a task to do this repeatedly. Does anyone have any quick fixes or have had experienced issues with phones becoming Unregistered?

I've had a handful of our phones become temporarily unregistered, but they pop back online within a few minutes. Each time I checked my network monitoring utilities and found no issues. The problem hasn't happened in quite some time though. The only recent memories of this were during network maintenance when the network was taken offline temporarily and they obviously lost their connections.

One thing you could try is assigning a static IP to your phones. It's rare (but possible) for them to lose connection temporarily once the assigned IP expires. In a normal DHCP environment this happens every week or so. Assigning a static IP to each phone would remove this possibility, and helps keep your IP Tables cleaner on the DHCP server.

I'd also recommend reviewing this article since this is what support will point you to anyway. I don't know how much oversight you personally have of the network at your office, but whoever manages the switches, router, and WAN link should be shown the article. It's a long read so skimming may be in order initially.

make sure your phones are on a VLan

VLAN isn't always an option if using the passthrough. Depends on the environment.

Check router/fitewall settings.

This is an incredibly vague answer. Not exactly helpful. It's like telling someone to 'check the engine' when their car breaks down.

Ongoing issue for years at several locations. Of course they are always going to blame your network
