Polycom 9.0.6 manual Including Multiple Sites in Calls, About Multipoint Calls

Getting Started Guide for the VSX Series

Including Multiple Sites in Calls

Your system may be configured to participate in multipoint calls. During a multipoint call, multiple sites can see and hear each other. You can also share content in a multipoint call, just as you can in a point-to-point call.

Some systems, such as the VSX 5000 and VSX 6000, are not compatible with the optional embedded MPPlus Multipoint software. These systems can be used to participate as a site in a multipoint call but cannot initiate a multipoint call.

If the multipoint call disconnects after five minutes, the system that you are using may only have multipoint demonstration capabilities. For information about adding the full version of embedded MPPlus Multipoint software, contact your Polycom sales representative.

About Multipoint Calls

You can host multipoint calls using a video conferencing system with multipoint capabilities, or you can use a bridge such as the Polycom MGC™ or the Polycom RMX 2000™. The way a multipoint call is hosted affects the conference as shown in this table:

Hosted by...	Lets you include...	Supports these calls...
Video Conferencing System	Number of sites allowed by the system	• Any combination of IP, ISDN,
		V.35/Serial, and audio-only
		• Any combination of SIP, ISDN,
		V.35/Serial, and audio-only
Bridge	Number of sites allowed by the bridge	• Any combination of IP, SIP, ISDN,
		V.35/Serial, and audio-only

Placing a Multipoint Call

How you place a multipoint call depends on whether you’re using a Polycom system with multipoint capabilities or a bridge such as the Polycom MGC.

•For calls hosted by a video conferencing system, you can define a multiple-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. The other sites can call the Polycom system to join the call.

•For calls hosted by a bridge, contact your system administrator for more information.

•VSX 3000, VSX 3000A, VSX 7000, VSX 7000s, and VSX 7000e systems with optional multipoint capabilities can host multipoint calls that include up
