Video Optimized
mode
is selected and according to the settings of the LYNC_AVMCU_1080p30_ENCODE _RESOLUTION
System Flag:
NO (Default) Video streams sent to and received from the MS AV MCU are HD720p30, SD, and CIF.

Limit Maximum Resolution for MS SVC Using a System flag

The MAX_MS_SVC_RESOLUTION System Flag can be used to minimizing the resource usage by
overriding the default resolution selection and limiting it to a lower resolution.
Range: AUTO, CIF, VGA, HD720, HD1080
Default: AUTO
The MAX_MS_SVC_RESOLUTION System Flag operates independently from the
MAX_RTV_RESOLUTION System Flag allowing differing maximum resolutions to be selected for the MS
SVC and RTV protocols.
If you want to modify System Flag values, the flags must be added to the System Configuration file. For
more information see:
Modifying System Flags
and
Controlling Resource Allocations for Lync Clients
Using RTV Video Protocol
in the Collaboration Server (RMX) Administrator’s Guide.
ICE Configuration
The Collaboration Server should be configured with ICE regardless of whether an EDGE Server is part of
the configuration or not.

Federation Configuration

A secondary SIP domain can be added to the Lync 2013 environment. It must be configured as Federated.

Appendix H - Integration Into Microsoft Environments

Server (RMX) Administrator’s Guide.
