Depending on the dialing direction, the following procedures must be performed:
Setting Flags on the Collaboration Server
When running conferences in mixed environment (Collaboration Server and MGC) there
may be small differences between the line rates each MCU is sending. In the Collaboration
Server, several flags must be set to ensure that these differences will not cause the cascaded
link to connect as Secondary and that Content flows correctly between the cascaded
conferences. This procedure is performed once per Collaboration Server.
To modify the flags:
1In the Collaboration Server Web Client menu, click Setup>System Configuration.
2In the System Flags dialog box, add the following new flags and values:
—MIX_LINK_ENVIRONMENT=YES
Setting this flag to YES will adjust the line rate of HD Video Switching conferences
run on the RealPresence Collaboration Server 1800 from 1920Kbps to 17897Kbps to
match the actual rate of the HD Video Switching conference running on the MGC.
In such case, the conference can include IP and ISDN participants.
—IP_ ENVIRONMENT_LINK=NO
Setting this flag to YES will adjust the line rate of HD Video Switching conferences
run on the RealPresence Collaboration Server 1800 from 1920Kbps to 18432Kbps to
