Deleting Contacts
You remove a Contact from the Contacts group by deleting it.
When you delete a presence service Contact, or a presence service Contact
rejects your invitation using Polycom CMA Desktop, you are deleted from one
another’s Contacts lists.
To delete a Contact:
1. Find the Contact in the directory Contacts group or on the Contacts home
screen.
2. Highlight the Contact and press on the remote control.
The Contact is deleted from the Contacts home screen. When you delete a
Contact that was added to the Speed Dial or Sites list on the Place a Call screen,
the entry is deleted from both screens.
You cannot delete default Contacts that come from the global directory server.
Including Multiple Sites in Calls
Your system may be configured to participate in multipoint calls. During a
multipoint call, multiple sites can see and hear each other. You can also share
content in a multipoint call, just as you can in a point-to-point call.
You can host multipoint calls using a video conferencing system with
multipoint capabilities, or you can use a bridge such as the Polycom
RMX 1000™, Polycom RMX 2000™, or Polycom MGC™.
Placing a Multipoint Call
How you place a multipoint call depends on whether you’re using a Polycom
HDX system with multipoint capabilities or a bridge such as the Polycom
RMX 1000, Polycom RMX 2000, or Polycom MGC. The number of sites
allowed in the call is determined by the capabilities of the system or bridge
hosting the call. The call can include any combination of IP H.323, SIP, ISDN,
V.35/Serial, and audio-only endpoints. For more information about call types,
refer to Types of Video Calls You Can Make on page 6.
• For calls hosted by a Polycom HDX system, you can define a multiple-site
directory entry to call all of the sites at one time. Alternatively, you can
place a call to the first site, and then add other sites after the first call
connects. The other sites can call the Polycom HDX system to join the call.
• For calls hosted by a bridge, you may need to enter calling information
about all of the sites before the call begins. Contact your system
administrator for more information.
