•G711A/U or G722 – Set this flag value according to the hosting workstation capabilities. If the MCU detects single core host during capabilities exchange it will assign a G.711 or G.722 Audio algorithm according to the flag value.

Possible values: AUTO, G711A, G711U, G722

Default: G711A

Controlling Resource Allocations for Lync Clients Using the RTV Video Protocol

The number of resources used by the system to connect a Lync client with RTV is determined according to the conference line rate and the Maximum video resolution set in the Conference Profile.

In versions 7.6 and earlier, when conferences are set to line rates above 600 kbps, the MCU could allocate up to three video resources to Lync clients connecting using the RTV video protocol.

From version 7.6.1, the system flag MAX_RTV_RESOLUTION enables you to override the MCU resolution selection and limit it to a lower resolution. Resource usage can then be minimized the 1 or 1.5 video resources per call instead of 3 resources, depending on the selected resolution.

Possible flag values are: AUTO (default), QCIF, CIF, VGA or HD720.

For example, if the flag is set to VGA, conference line rate is 1024Kbps, and the Profile Maximum Resolution is set to Auto, the system will limit the Lync RTV client to a resolution of VGA instead of HD720p and will consume only 1.5 video resources instead of 3 resources.

When set to AUTO (default), the system uses the default resolution matrix based on the conference line rate.

To change the default flag setting, add the MAX_RTV_RESOLUTION flag to the System Configuration flags and set its value. For information, see .

The following table summarizes the MCU resources allocated to a Lync Client based on the MAX_RTV_RESOLUTION flag setting, the connection line rate and the video resolution.
