Include Multiple Sites in a Cascaded Call
You can include multiple sites in a cascaded call if the sites you call have internal multipoint capability. The
following diagram shows how to do this.
Cascaded call with multiple sites
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.
Keep the following points in mind regarding cascaded calls:
●
H.239 is not supported in cascaded calls.
●
Cascaded multipoint is not supported in SIP calls.
●
HD and SD multipoint are not supported when the Polycom RealPresence Group system hosts a
cascaded call.
●
You cannot change the near-end layout.
●
The encryption padlock icon might not accurately indicate whether a cascaded call is encrypted.
●
You cannot call a group of contacts by using Speed Dial or Favorites to call the group.
