Note

cacN/A

Call Admission Control (CAC) parameters for all peers using this zone.

bandwidthLimit0-2147483647, or unlimitedTotal bandwidth limit in Kbps/sec.
bandwidthLimitThreshold0-100Bandwidth utilization notification threshold, as a percentage. (default = 0)
bandwidthVideoThreshold0-100

Enter threshold value (as a percentage of video bandwidth) to limit video streams to a specific bandwidth to prevent video calls consuming call bandwidth otherwise needed for audio calls. (default = 0)

callLimit0-2147483647, or unlimitedTotal number of calls allowed on this zone. (default = 'unlimited')
callLimitThreshold0-100Call limit utilization notification threshold, as a percentage. (default = 0)
egressN/AEgress-specific call admission control configuration. See the Egress Parameters table below for details.
emergencyOversubscription0-1000, or unlimitedThis parameter gives priority treatment to emergency calls by specifying the resource over-subscription percentage allowed for emergency calls, and represents the allowed percentage of emergency calls beyond the configured call limit. When the call limit is reached, normal calls are rejected but emergency calls are accepted up to an expanded limit. (default = 10)
extendedEmergencyIpLimit0-40000Additional number of emergency calls (expressed as a numeric value) allowed if call limit and emergency over-subscription quota are exhausted. (default = 0)
hpcOversubscription0-100This parameter specifies the amount of resource over-subscription (as a percentage) allowed for HPC calls. When the baseline call limit and bandwidth limit are reached, normal calls are not admitted, but additional HPC calls are allowed up to the configured percentage value. (default = 10)

ingress

N/A

Ingress-specific call admission control configuration. See the Ingress Parameters table below for details.
