Setting the Date and Time
EAP-TLS uses certificate based authentication that requires the internal clock on the Cisco Unified
Wireless IP Phone 7925G to be set correctly. The date and time on the phone might change when it is
registered to Cisco Unified Communications Manager.
If a new server authentication certificate is being requested and the local time is behind the Greenwich
Note
Mean Time (GMT), the authentication certificate validation might fail. It is recommended that you set
the local date and time ahead of the GMT.
To set the phone to the correct local date and time, follow these steps:
Procedure
Select Date & Time from the left navigation pane.
Step 1
If the setting in the Current Phone Date & Time field is different from the Local Date & Time field, click
Step 2
Set Phone to Local Date & Time.
Step 3 Click Phone Restart, then click OK.
