Cisco Cisco Unified MeetingPlace Video Integration Release Notes

SCCP flow control 

When there is only one video-enabled participant in the conference (i.e. the participant that 
opened the video channels), the MCU sends a flow control message to that station with a bit rate 
value of 0.

When a second video-enabled participant joins the conference, the MCU sends a flow control 
message to the first participant with the original bit rate value.

The effects on SCCP conference endpoints are as follows:

Regular— Lowering/returning bit rate as described above. If only one video-enabled participant 
is present, the participant sees a still image in the video window.

Modified (CUVA)—When the bit rate is set to 0, the video window closes. When the bit rate is 
returned to the original setting, the video window reopens.

Set the sccpsendfctofirstvcall advanced command to 1 to enable SCCP flow control. The 
advanced command is set to 0 by default.

SCCP Partitioning resources support API. The MCU reports via the XML API the level of resources 
available for non-SCCP calls.

XML API Get Conferences List Request supports the use of a user name/password combination.
