which implies that all participants must connect at the same line rate
and use the same video resolution. Participants with endpoints that
do not support the selected line rate and resolution will connect as
secondary (audio only).
For more information, see "Video Switching (VSW) Conferencing” on
page 2-6.
Notes:
• Video Switching conferencing mode is unavailable to ISDN
participants.
• To connect to a Video Switching conference via Entry Queue, the
Profile assigned to the Entry Queue must be set to Video
Switching. It is recommended to use the same profile for both the
destination conference and Entry Queue.
• Telepresence Mode is unavailable in Video Switching
conferences.

Switching conferences.

selected.
If H.264 is not the selected video protocol the check box is inactive
(grayed out). For more information, see "H.264 High Profile Support
in Video Switching Conferences” on page 2-62.

Field/Option Description
Selecting a new conference line rate lower than the initial line rate selected for the conference (for
example, changing from 4096 kbps to 1532 kbps) may result in system reverting to the default
resolution for that line rate (for example, 720p instead of 1080p). You may need to select the
required resolution again, provided the selected line rate is higher than the minimum threshold line
rate defined for that resolution in the system configuration. For more details, see “Minimum
Threshold Line Rate System Flags” below.
