Configuring Multipoint Calling
You can use your Polycom HDX system to participate in multipoint
conferences. Multipoint conferences include multiple video sites and can also
include voice-only sites. During a multipoint call, 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.
The Polycom HDX systems can host multipoint calls. These systems can also
use the Conference on Demand feature of Polycom’s PathNavigator for
multipoint calling.
Depending on your Polycom HDX system model, you may need to enter a
multipoint option key to enable multipoint calling.
Entering a Multipoint Option Key
Before placing multipoint calls, you may need to enter a multipoint option key.
A five-minute multipoint trial is available. You can also enter a 6 Mbps MP
option key to enable the system to use up to 6 Mbps in combined call rates for
multipoint IP calls.
For information about purchasing a multipoint call option, please contact your
Polycom distributor.

To enable or disable multipoint trial mode:
1. Go to System > Admin Settings > General Settings > Options.
