To place a cascaded call:
Create and call a group in the directory, or place calls one at a time to
1
several other sites.
Ask each far site to call additional sites. Along with these additional sites,
2
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 using Conference on Demand.
• Chair control, People+Content, and H.239 are not supported in cascaded calls.
• Cascaded multipoint is not supported in SIP calls.
• HD and SD multipoint is not supported when the Polycom HDX system hosts a
cascaded call.
• Only Full Screen multipoint mode is available in cascaded calls.
• The encryption padlock icon might not accurately indicate whether a cascaded
call is encrypted.
• Full Screen multipoint mode in a mixed-types call is available only if the call is
placed from the originating HDX system. Mixed-type calls from the
non-originating HDX system will use the Auto multipoint mode. See
