Startup and Connectivity Problems
After installing a Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G in your network and adding
it to Cisco Unified Communications Manager Administration, the phone should start up as described in the
Phone Startup Process, on page 64. If the phone does not start up properly, see the following sections for
troubleshooting information.
Incomplete Startup Process
Problem
The phone does not start up and information does not display on the phone.
Cause
When an IP Phone connects to the wireless network, the phone should go through its normal startup process
and the phone screen should display information.
If the phone does not complete the startup process, the cause might be due to low RF signal strength, network
outages, a dead battery in the phone, or the phone might not be functional.
