Troubleshooting the Polycom CX300 Phone
Draft 1 7
Understanding Display Messages
The phone display still shows the startup screen after I have connected it to the
computer and waited more than a minute.
The phone display shows “Sign in to Office Communicator” even when the
phone is already connected to my computer.
One or a combination of the following conditions might apply:
• The phone might not be communicating with Microsoft Office
Communicator 2007 R2 because the computer is in sleep mode.
If your computer is in sleep mode, take it out of sleep mode so that it can
communicate with Microsoft Office Communicator and your phone.
• Microsoft Office Communicator 2007 R2 is not running or you have not
signed in to your account.
If you cannot sign in to your Office Communicator account, see
Troubleshoot sign in in Office Communicator Help at
http://go.microsoft.com/fwlink/?linkid=162629 and contact your
system administrator.
• The version of Microsoft Office Communicator does not support the
phone or Microsoft Office Communicator is not detected on the computer.
Your computer must be running Microsoft Office Communicator 2007 R2
version 3.5.6907.37 or later versions for the phone to function. Also,
confirm that all Windows service packs available for the computer's
operating system were installed.
• Another telephone device is connected to the same computer and selected
as the default device for Microsoft Office Communicator 2007 R2.
The Polycom CX300 phone display will continue to show the Sign in
message until it is selected as the default device for Microsoft Office
Communicator 2007 R2 or until the other device selected is disconnected.
To change the device selected for Microsoft Office Communicator 2007 R2,
go to Tools (by clicking in the upper left corner of the window) in
Microsoft Office Communicator 2007 R2, select Set Up Audio and Video,
and select the Polycom CX300 phone from the applicable drop-down
menu.
• The phone’s USB plug was disconnected and then reconnected too quickly
to the computer.
Disconnect the phone’s USB plug from the USB port, wait 10 seconds, and
then reconnect it.
