The following diagram shows how to do this.
To place a cascaded call:
1 Create and call a group in the directory, or place calls one at a time to
several other sites.
2 Ask each far site to call additional sites. Along with these additional sites,
each far site in the original multipoint call can add one audio-only
connection.
