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 cascaded calls:
• You cannot place cascaded multipoint calls through PathNavigator.
• Polycom StereoSurround, Pro-Motion, AES encryption, continuous presence,
chair control, People+Content, and H.239 are not supported in cascaded calls.
• H.264 is only supported when all of the MCUs are VSX 8000 systems and each
VSX 8000 calls no more than three other systems.
