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 RMX to send a busy notification to a SIP audio endpoint or
a SIP device when dialing in to the RMX whose audio resource usage exceeded the Port
Usage threshold.
The RMX 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.
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.
