Polycom VSX Series manual Including More Than Three Other Sites in a Cascaded Call

Customizing the VSX System

Points to note about PathNavigator’s Conference on Demand:

• Once the call begins, users cannot add another site to the call — even if the site was in the call originally and is attempting to rejoin. Because of this, you cannot place cascaded multipoint calls through PathNavigator.

•The MGC needs to have enough ports available to complete the call. The system displays a message if the MGC does not have enough ports (resources) available to connect all the sites.

Including More Than Three Other Sites in a Cascaded Call

You can include multiple sites in a cascaded call if the sites you call have the internal MCU capability. The following diagram shows how to do this.

To place a cascaded call:

1.Create and call a multiple-site entry from the directory, or place calls one at a time to up to three other sites.

2.Ask each far site to call up to two additional sites. Along with these additional sites, each far site in the original multipoint call can add one audio-only connection.
