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.
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.
