IP phones on 200icp restarting

[busster]

I have 5 ip phones on a 200icp that will randomly restart on the average about once a day. They do not all restart at once and can not find anything that would be causing the restart.

-Are there any indications of troubles in the logs?
-Have there been any changes to the network?
-Have you changed anything in the SX200 ICP?
-Are all the sets on the same POE switch, are there other sets on that POE switch having the same issues?
-Are there specific times (high volume of calls) when the sets reboot?
-Are the IP sets and data network all the same VLAN?

The more information you can give, the better answers you'll receive.

Sounds to me like a DHCP lease timer expiring and also having issues renewing IP addresses.

We had a similar problem when we had a virus outbreak that caned our core switch. So, my first thought is heavy network activity.
