We have seven phones that reboot themselves at 3AM every morning. The phones are in three different buildings, four different departments, and two different 3300s. Some connect via a StreamLine unit, the reset via Ethernet cables, connected to two different switches. No other phones are affected.
Here's an excerpt from the log: An IP device, with DN 7701, registered at CDP L2 MAC address Not Supported, CDP L2 Port Not Supported, CDP L2 IP Address:
The connection to the heartbeat server is lost just before we lose the phones.
Early in this problem I changed out the 8101 phone, and changed the port on the switch. It seemed to fix the problem for a few days, but then it started again.
Any ideas? I've heard something about DHCP lease renewal, on another board.
The phones work perfectly, other than this issue.
Thank you for your help.
