One CIF video resource equals 3 voice resources. All resources are taken from the same pool
of video resources.

Forcing Video Resource Allocation to CIF Resolution

You can set the MCU to allocate one CIF video resource to an endpoint, regardless of the
resolution determined by the Conference Profile parameters. This forcing saves resources
and enables more endpoints to connect to conferences.
The forcing is done by modifying the system configuration and it applies to all conferences
running on the MCU.
You can specify the endpoint types for which resource allocation can be forced to CIF
resource, enabling other types of endpoints to use higher resolutions in the same conference.
For example, you can force the system to allocate one CIF video resource to CMAD and VSX
endpoints while HDX endpoints can connect using SD or HD video resources.
Once the endpoint connects to the conference, its type is identified by the Collaboration
Server and, if applicable, the Collaboration Server will connect it using one CIF resource,
even if a higher resolution can be used.
