GETTING STARTED GUIDE FOR THE VSX SERIES

Including Multiple Sites in Calls

You can use the VSX system to participate in multipoint conferences. During a multipoint conference, a multipoint conferencing unit (MCU) enables the video to switch between sites so that you can always see and hear the participant who is speaking. You can also share content in a multipoint call, just as you can in a point-to-point call.

About Multipoint Calls

With the VSX system you can make multipoint calls using an external MCU or the internal multipoint option. The type of MCU affects the conference as shown in this table:

For calls using the internal MCU option, the VSX system can initiate the call or the other sites can call the VSX system to join the conference.

Placing a Multipoint Call

How you place a multipoint call depends on whether you’re using the internal MCU option or an external MCU. If your organization uses Polycom’s PathNavigator, you can also use PathNavigator’s Conference on Demand feature to place multipoint calls.

‰For calls using the internal MCU option, you can define a multi-site directory entry to call all of the sites at one time. Alternatively, you can place a call to the first site and then add other sites after the first call connects.

‰For calls using an external MCU, you may need to enter calling information about all of the sites before the call begins. Contact your system administrator for more information.

‰For calls using PathNavigator’s Conference on Demand feature, the system administrator must:

ƒRegister the VSX system with PathNavigator.

ƒConfigure the VSX system to use PathNavigator for multipoint calls.
