Chapter 5-Cascading Conferences

rate of the IP Only HD Video Switching conference running on the MGC. In such case, the conference can include IP Only participants.

If the flag MIX_LINK_ENVIRONMENT is set to YES, the IP_LINK_ENVIRONMENT flag must be set to NO.

If the flag MIX_LINK_ENVIRONMENT is set to NO, the IP_LINK_ENVIRONMENT flag must be set to YES.

—H263_ANNEX_T=YES (default)

This flag enables/disables the use of Annex T with H263. Set it to NO if the endpoints connecting to the conference do not support this mode. In such a case, you must also change the MGC flag ENABLE_H239_ANNEX_T setting to NO.

—FORCE_1X1_LAYOUT_ON_CASCADED_LINK_CONNECTION=YES (default).

Set this flag to NO If the MGC is functioning as a Gateway and participant layouts on the other network are not to be forced to 1X1.

3If the MGC is dialing the RMX and the cascaded link connects to the conference via the Cascade-enabled Entry Queue without being prompted for the conference password, set the flag to YES as follows:

— ENABLE_CASCADED_LINK_TO_JOIN_WITHOUT_PASSWORD=YES

4Click OK.

5Reset the MCU to apply the changes.

Setting Flags in the MGC

Flag setting is required to ensure the correct MCU behavior for cascading conferences. It is performed once per MCU.

To modify the flags:

1In the MGC Manager, right-click the MCU icon and then click MCU Utils>Edit “system.cfg”.

2In the H264 Section, ensure that the following flags are set to:

—ENABLE_HD_SD_IN_FIXED_MODE=YES

Setting this flag to YES enables H.264 Standard Definition (SD), High Definition (HD) and VSX 8000 (Version 8.0) support in Video Switching conferences.

—H264_VSW_AUTO=NO

Setting this flag to NO disables the highest common mechanism in H.264 and enables the selection of H.264 Video Protocol in fixed mode in Dual Stream Video Switching cascading conferences.

—ENABLE_H239_ANNEX_T=YES

This flag should be set to the same value (YES/NO) as the settings of the RMX flag H263_ANNEX_T

To use MIH Cascade in the MGC, the Conference Numeric ID routing mode must be used. It is determined when the system.cfg flag in the GREET AND GUIDE/IVR section is set to QUICK_LOGIN_VIA_ENTRY_QUEUE=NO.

3Click OK.

4If you changed the flags, reset the MCU.
