Description (partial)

The static IP address setting on CP-7937G changes to DHCP address if the PoE is unplugged and plugged back during boot-up. The disabled DHCP option shows up as enable DHCP with new IP address.

This only happens in certain timing -the PoE is disconnected and connected back while the phone screen turns to black- in boot-up procedure.
And when you debug a phone using SSH, this is not reproducible.
