Note: when connecting the Duet Executive to external speakers, as described in section 4, the 
Executive will also send your telephone’s audio to the external speaker (or headphones). While the 
internal Duet speaker is disabled when using this connection, the Duet’s internal microphone is still 
functional. This feature is useful if, for example, you listen to music stored on your computer while 
wearing headphones and the telephone rings. You can pickup the call without taking the 
headphones off. It can also be useful if you want to have a private conversation using standard 
headphones without the need to purchase a telephone headset.
VoIP – Telephone bridge:
When the Duet Executive is connected to both your computer and your telephone, you can conduct 
both a telephone and VoIP conversation. The Executive will allow you to communicate with both the 
telephone and the VoIP parties at the same time. When a simultaneous conversation occurs, the 
Duet will bridge between your telephone and your VoIP ends, allowing them to communicate with 
each other in addition to communicating with you.
This feature is very convenient if you are on a VoIP call and want to patch-in a person that has no 
access to a computer. Simply call him/her using your telephone, while keeping the VoIP call alive. 
This feature also allows you to record a telephone conversation on your PC. All you need to do is to 
download Phoenix Audio’s free recording utility, which can be found on our website:
