Description
When set to NO (default), the ICE channel is closed
after applying CAC bandwidth management when
Call Admission Control is enabled in the local
network.
When set to YES, the ICE channel remains open
throughout the call.
Default value: NO
Possible values: YES/NO
Used to prevent reassignment of cells in a forced
layout that were assigned to endpoints that have
disconnected, paused their video, or have been
removed from the conference. The cell will remain
black until the endpoint reconnects or a new layout is
used, or the conference ends.
Range: YES/NO
Default: NO
• NO - Cells of dropped endpoints are reassigned.
Endpoints that reconnect will be treated as new
endpoints.
• YES - Cells of dropped endpoints are not
reassigned, but will be reserved until the endpoint
reconnects.
Forced Layout Guidelines:<can guidelines be
included in the table>
• It is recommended that this flag be set to YES if
the RealPresence Collaboration Server is used
primarily for ITP conferences with MLA.
• When a new forced layout is sent to the MCU, the
MCU no longer preserves the cells for
disconnected participants. The layout is redrawn
using the currently connected participants only.
• If the dropped endpoint was forced to use a
particular cell, and that cell is switched from the
forced layout to automatically assigned, the MCU
no longer preserves the cell. Any other endpo int
can be assigned to that particular cell.
• This feature works the same way in Telepresence
conferences, even where the layouts are
controlled by the MLA.
If there is a slow response from the ISDN-video
switch, ISDN-voice dial-out ringing duration (in
seconds) is used by the RealPresence Collaboration
Server to disconnect the call.
Default value: 45
