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.
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:
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
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.
