AVC Conferencing - Voice

In Collaboration Server 1500/2000/4000 in MPMx Card Configuration Mode, one Audio Only resource is
used to connect a single voice participant when CIF resources have been converted to Audio Only.
However, if no CIF resources were converted, Audio Only endpoints use one CIF video resource per
connection.
When video ports are fully used, the system cannot use free audio ports for video. When audio port
resources are fully used, video ports can be used, using one video port to connect one voice participant.
In Collaboration Server 1500/1800/2000/4000 in MPMRx Card Configuration Mode, a voice port equals a
CIF video port and there is no differentiation between voice and video ports.

Resource Capacity Modes

The installed media card type (MPMx or MPMRx) determines the Card Configuration Mode, which in turn
determines the resource allocation method that can be selected for the MCU. The resource allocation
method determines how the system resources are allocated to the connecting endpoints and it is defined in
the Video/Voice Port Configuration. Two allocation methods are available:
● Flexible Resource Capacity™ – This is the default allocation mode that is used in all versions and
can be used in all Card Configuration Modes and applies to all Conferencing Modes (SVC and AVC
conferencing). The resources are only set to audio and video as a pool and the system allocates the
resources according to the connecting endpoints. This mode offers flexibility in resource allocation
and is available in MPMx and MPMRx Card Configuration Modes.
In Flexible Resource Capacity mode, in MPMx and MPMRx Card Configuration Modes, the maximum
number of resources is based on the system license, regardless of the hardware configuration of the
MCU. These resources are allocated as CIF resources by default.
Example: If the MCU is licensed for 80 video resources, but only one Media card is currently installed
in the MCU, the system lets you allocate 80 ports although only 40 video resources are available for
participant connection. (However, an active alarm will be added to the Active Alarms list indicating a
resource deficiency).
From Version 8.1, only the MPMx Media Card and Card Configuration Mode are supported.
