Phone does not activate after 
connecting it the first time. 

Unless your System Administrator has already initialized 
your telephone, you might experience a delay of several 
minutes before it becomes operational. Upon plug-in, your 
telephone immediately begins downloading its operational 
software, its IP Address, and any special features 
programmed by your System Administrator from the 
server to which it is connected. Report any delay of more 
than 10 minutes to your System Administrator.

Phone does not activate after a 
power interruption. 

Allow a few minutes for re-initialization after unplugging, 
powering down the phone, server problems, or other 
power interruption causes.

Phone worked earlier but does 
not currently seem to work.

Contact your System Administrator.

Ask your System Administrator if your Speaker was

From another phone, place a call to your extension to test 
this suggested solution. 

Display shows an error/
informational message.

Most messages involve server/phone interaction. 
If you are on a call and the display suddenly shows 
“Discovering...,” the network connection between the 
telephone and the call server was interrupted, but your call 
stayed connected. The telephone automatically starts to 
re-register with the call server, but until re-registration 
succeeds, you do not have access to switch features and 
functionality such as Transfer, or to administered Feature 
buttons.
If you cannot resolve the problem based on the message 
received, contact your System Administrator for resolution.
