 Customizing the VSX System

4 - 43

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.

Create and call a multiple-site entry from the directory, or place calls one 

at a time to up to three other sites.

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.

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.
