Description (partial)

Symptom:
Cisco IP phones do not log or update their missed, placed, and received call history.

Conditions:
Occurs when the phone cannot download a TFTP configuration file.  This is seen when the phone does not receive an option 150 IP address or option 66 from a DHCP server or the phone does not have alternate TFTP enabled and set to a valid TFTP IP address.

If an IP phone successfully downloads a TFTP configuration file and later loses connectivity to the TFTP server the phone will log missed, placed, and received calls.  The phone continues logging even after a reset because of the cached configuration file.  Once the phone is power cycled call logging will stop, until the phone is able to download it's TFTP configuration file again.
