Resolving Startup Problems

After installing a Cisco IP Phone into your network and adding it to

Cisco CallManager, the phone should start up as described in the “Verifying the Phone Startup Process” section on page 3-9. If the phone does not start up properly, these sections can help you resolve the problem:

•Symptom: Cisco IP Phone Does Not Start Up, page 6-12

•Symptom: Cisco IP Phone Not Registering with Cisco CallManager, page 6-13

•Symptom: Cisco IP Phone Resetting, page 6-18

Note Any procedures that refer to an LCD screen display problem apply only to the Cisco IP Phone models 7905G/7912G.

Symptom: Cisco IP Phone Does Not Start Up

If you connect a Cisco IP Phone into the network port, the LEDs should light up and, on the Cisco IP Phone models 7905G/7912G, messages should appear on the LCD display. (See the “Verifying the Phone Startup Process” section on page 3-9for information on the normal startup process.) If the phone does not proceed through this normal startup process, you must determine if the phone is functional or if anything else in the configuration is causing the phone to not start up properly.
