Setting the Port Usage Threshold

To Set the Port Usage Threshold:

1In the Setup menu, click Port Gauge to open the Port Gauge dialog box.
2Enter the value for the percentage capacity usage threshold.
The high Port Usage threshold represents a percentage of the total number of video 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%.
3Click OK.
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.
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
