2 Enter the value for the percentage capacity usage threshold.
The value is applied to the Audio and video resources according to the Video/Voice Port
Configuration.
The high Port Usage threshold represents a percentage of the total number of video or voice ports
The high Port Usage threshold represents a percentage of the total number of video or voice ports
available. It is set to indicate when resource usage is approaching its maximum, resulting in no free
resources to run additional conferences. When port usage reaches or exceeds the threshold, the red
area of the gauge flashes. The default port usage threshold is 80%.

SIP Dial-in Busy Notification
When the system flag SEND_SIP_BUSY_UPON_RESOURCE_THRESHOLD is set to YES (NO is the
default), it enables the MCU to send a busy notification to a SIP audio endpoint or a SIP device when dialing
in to the MCU whose audio resource usage exceeded the Port Usage threshold.
default), it enables the MCU to send a busy notification to a SIP audio endpoint or a SIP device when dialing
in to the MCU whose audio resource usage exceeded the Port Usage threshold.
The Collaboration Server will send a SIP busy response to SIP audio endpoints when:
● The system flag SEND_SIP_BUSY_UPON_RESOURCE_THRESHOLD is set to YES (NO is the
default)
● The port usage threshold for Audio resources is exceeded. The threshold is defined in the Setup >
Port Gauge dialog box.
When the flag is set to YES, the system will allow SIP audio endpoints to connect to the MCU until the Port
Usage threshold is reached. Once this threshold is exceeded, the SIP audio endpoints will not be able to
connect, ensuring that the remaining system resources can be used by all other connections, including SIP
video H.323 cascaded links and ISDN video. When the call is rejected by the MCU because of lack of
resources, the appropriate indication will be sent by the MCU to the SIP audio endpoint.
