Method II
Depending on the dialing direction, the following procedures must be performed:
Setting Flags on the RMX
When running conferences in mixed environment (RMX and MGC) there may be small
differences between the line rates each MCU is sending. In the RMX, 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 RMX.
To modify the flags:
1
In the RMX Web Client menu, click Setup>System Configuration .
2
In 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 (RMX) 1500/2000/4000 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
