Cisco 7985 troubles

Cisco 7985 IP phone unregisters after some period of time. When I plug it out and in again, it registers with the Call Manager, but becomes unavailable in 5-10 minutes. I have to unplug it and plug it in again to make it work. Other phones work fine.

Can it be just a communication problem somewhere in the wires?

This is what I found in RTMT for this phone:

DirectoryNumberMismatch

DeviceInitiatedReset

What are the reasons behind these logs?

Are you using DHCP to reg the phone?

Yes, the phone registers over VPN site-to-site connection. Default gateway ping statistic is ok, no packet loss at all. Not sure about DHCP, probably yes.

CM version 6.0.1.2000-4
