Polycom 1500/1800/2000/4000 manual Setting Flags in the MGC

Defining Cascading Conferences

3If the MGC is dialing the RealPresence Collaboration Server 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 select 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 RealPresence Collaboration Server 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.

Method II - Defining the Cascading Entry Queue in the MGC

The Entry Queue definition on the MGC is required if the dialing is done from the RealPresence Collaboration Server to the MGC.

To define the Cascading Entry Queue in the MGC:

1In the MGC Manager, expand the MCU tree.

2Right-click the Meeting Rooms, Entry Queues and SIP Factories icon and click New Entry Queue.
