Cisco IP Telephony Troubleshooting Guide for Cisco CallManager Release 3.0(1)

There should be one Warning and one Error message for each phone that resets. In this case, the problem is often that the phone cannot keep its TCP connection to the Cisco CallManager alive, so the Cisco CallManager resets the connection. This may be because a phone was turned off or there may be a problem in the network. If this is an intermittent problem, it may be useful to use Microsoft Performance to record phone registrations.
