does not support these features.
Phone Does Not Register with Cisco Unified Communications Manager
If a phone proceeds past the first stage (authenticating with access point) and continues to cycle through the
messages displaying on the phone screen, the phone is not starting up properly. The phone cannot successfully
start up until it connects to the LAN and registers with a Cisco Unified Communications Manager server.
The following sections can assist you in determining the reason that the phone is unable to start up properly.
Cisco Unified Communications Manager Phone Registration Rejected
Problem
The error message Registration Rejected displays.
Cause

if the phone has been added to the server or if autoregistration is enabled.
Solution
Review the information and procedures in Add Users to Cisco Unified Communications Manager, on page
171 to ensure that the phone has been added to the Cisco Unified Communications Manager database. Verify
that the phone is in the Cisco Unified Communications Manager database, using Device > Phone > Find
