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.
About Multipoint Calls
You can host multipoint calls using a video conferencing system with
multipoint capabilities, or you can use a bridge such as Polycom MGC™. 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
HDX system with multipoint capabilities or a bridge such as Polycom MGC.
‰ For calls hosted by a Polycom HDX 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 HDX system to join the
call.
‰ For calls hosted by a bridge, you may need to enter calling information
about all of the sites before the call begins. Contact your system
administrator for more information.
To place a multipoint call by adding sites to a call:
1. Call the first site.
2. When the call connects, press Call on the remote control.
3. Select Add Call, and place a call to the next site.
4. Repeat steps 2 and 3 until all sites are connected.
