• The user is accessing Microsoft Office Communicator 2007 R2 in a Remote 

Desktop session. 
Microsoft Office Communicator 2007 R2 voice features are not supported 

in remote desktop scenarios. Therefore, the user may see a Sign in message 

even when signed in to Office Communicator during a Remote Desktop 

session.

• The connection to the network is lost.

Check whether your computer is running a version of Microsoft Office 

Communicator that does not support the Polycom CX300 phone. 
Uninstall the version of Microsoft Office Communicator currently on the 

computer. Then, install Microsoft Office Communicator 2007 R2 version 

3.5.6907.37 or a later version.

Check that the handset is resting on the hookswitch. 

This is typical behavior when a program other than Microsoft Office 

Communicator 2007 R2 is streaming audio through the phone.
In computers that are running Windows Vista operating systems, the Polycom 

CX300 phone display will show audio graphics even if audio has stopped 

streaming, as long as the audio application is still running.

First, follow these steps:

• Confirm that the computer is running a version of Microsoft Office 

Communicator that supports the phone. The user must be signed in to 

Microsoft Office Communicator.

• If the user has just changed the default audio device setting of their 

computer in Control Panel, you must perform one of these steps:
— Exit and then restart Microsoft Office Communicator.
— Disconnect the phone from the computer, wait 10 seconds, and then 

reconnect.
