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.
For example, if the Port Gauge threshold is set to 80%, when 80% of the Audio resources are
used, the system will not allow additional SIP audio endpoints to connect and will send a
busy notification to the endpoint.
This does not affect the video resources usage.
Port Usage Gauges
The Port Usage Gauges are displayed in the Status Bar at the bottom of the Collaboration Server
Web Client screen.
The Port Usage gauge
s indicate:
• The total number of Video
or Voice ports in the system according to the Video/Voice Port
Configuration. The Audio gauge is displayed only if Audio ports were allocated by the
administrator, otherwise only the Video port gauge is displayed.
• The number of Video
and Voice ports in use.
