Connecting Mobile Phone and Computer Audio
This feature allows you to use your conference phone to carry on 
conversations from your mobile phone or computer’s calling application (for 
example, Skype
™
, Microsoft® Lync™ 2010, MSN® Messenger, or Yahoo!
®
 
Messenger).
For example, if you’re in a call on your mobile phone, you can connect your 
mobile phone to the conference phone using Polycom’s Mobile Phone Cable. 
Or, if you’re in a call using Skype, you could connect your computer to your 
conference phone using Polycom’s Computer Calling Cable. Your conference 
phone’s speaker and microphones can then be used to include everyone in the 
conference room or office in the conversation.
Before you use a mobile phone or computer audio source with your phone, 
you need to set the audio type so your phone will know what kind of audio is 
connected.
Setting the Audio Type
You need to assign an audio type (mobile phone or computer) so your phone 
knows what kind of audio is attached. When you select the appropriate audio 
type, the SoundStation Duo will deliver optimal audio levels.
To connect a mobile phone or computer audio source to your conference phone, 
you require optional cables that are not included with your conference phone. For 
information about how to obtain the optional accessories, see your phone reseller.
For information on how to connect the cables to the 2.5mm port on your conference 
phone, see the Quick Start Guide for the Polycom SoundStation Duo Conference 
Phone available from the SoundStation Duo Support web site.
If you want to connect a mobile phone to the SoundStation Duo, be aware of the 
following:
• The optional Mobile Phone Cable connects to the headset connector on your 
mobile phone. If your mobile phone does not support this type of connection, 
you will need an adapter (not included).
• Full duplex audio quality may not be supported when the SoundStation Duo is 
connected for conferencing through a mobile phone, and diminished audio 
quality may occur. This can be the result of poor signal quality on the mobile 
phone network, as well as incompatibilities between the mobile phone and the 
SoundStation Duo.
