Message
Service Name
If you have selected a Message Service type other
than None, select the name of the AV Message
Service for Welcome (No Wait) or Welcome (Wait)
conference or the name of an IVR Service for an
IVR-enabled conference.
Note: If left blank, the system automatically selects
the default IVR or AV Message Service (depending on
the attended conference type).
Conference On
Port (COP)
This option is available if Continuous Presence
(Classic & Quad Views) was selected as the Video
Session type (in the Conference Properties - General
tab).
Click this check box to set this conference to
Conference On Port. For more details, see
“Conference On Port (COP)” on page 4-25.
For a COP session, select the estimated highest
transfer rate common to all participants. This (CP
COP) method forces all conference participants to use
the same video parameters. For example, if two
participants connect at a rate of 384 Kbps and one
participant connects at a rate of 128 Kbps, all
participants will connect, but the video quality will be
that of the 128 Kbps participant for all participants.
To maintain a minimum video quality for a Conference
On Port, a minimum threshold line rate must be
supported by participants. This threshold is
determined by the conference line rate. For example,
in a conference defined with a line rate of 768 Kbps, a
participant with a line rate of 128 Kbps will connect as
Secondary (audio only), in order to preserve the video
quality of the conference.
For the list of line rate thresholds, see Table 4-1,
“Conference On Port Line Rate - Minimum
Thresholds,” on page 4-25.
Encryption Select this check box to enable encryption for this
conference. For more information, see the MGC
Manager User’s Guide Volume II, Chapter 1, “Media
Encryption”.
