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?

Hi,
Are you using DHCP to reg the phone?
Are you registering IP phone over the wan?
Which version of CM are you using?
Plz reply
Thanks,

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
