Configuring Multipoint Calling
You can use the ViewStation systems to participate in multipoint conferences.
Multipoint conferences include multiple video sites (IP and ISDN) and can also
include voice-only calls. During a multipoint conference, a multipoint
conferencing unit (MCU) enables the video to switch to the various sites so that
you can see and hear the other conference participants.
You can use the internal MCU or the Conference-on-Demand feature of Polycom’s
PathNavigator for multipoint calling.
The ViewStationFX and VS4000 are automatically enabled for multipoint calling.
If you are using a ViewStationEX, you need to enter a multipoint option key to
enable multipoint calling.

Entering a multipoint software registration key (ViewStation EX only)

Before placing multipoint calls with your ViewStationEX, you must enter a
multipoint software registration key.
1. Go to System Info > Admin Settings > Software/Hardware > System
Options.
2. Enter the multipoint key provided.
For information about purchasing the multipoint call option, please contact your Polycom
distributor.
