Command Parameters

Zone CAC Parameters


Parameter

Length/Range

Description

zone

1-23

The name of the zone. You can configure signaling, media, and control for a zone in the address context.

Zone name is unique across all address contexts.
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 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 Ingress Parameters table below for details.

registrationLimit0-2147483647, or unlimitedThe number of concurrent registrations allowed in this zone. (default = 'unlimited')

Command Parameters

Egress Parameters


ParameterLength/RangeDescription
callBurstMax

SBC 5000:
1-900, or unlimited.

SBC 7000:
1-2700, or unlimited

Maximum allowed burst (above the allowed sustained rate) for egress call attempts, in calls/second. (default = 'unlimited')
callLimit0-2147483647, or unlimitedTotal number of outbound concurrent calls allowed. (default = 'unlimited' )
callRateMax

SBC 5000:
1-450, or unlimited.

SBC 7000:
1-1350, or unlimited

Maximum sustained egress call rate allowed in calls/second. (default = 'unlimited' )

You can set both callRateMax and callBurstMax as “unlimited”; however, if you assign a value to one parameter, the other must also be assigned a value.
emergencyOversubscription0-1000Over-subscription of resources (as a percentage) allowed for emergency calls. (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)
registerBurstMax

SBC 5000:
1-200, or unlimited

SBC 7000:
1-600, or unlimited

Maximum allowed burst (above allowed sustained rate) for egress initial SIP registrations. (default = 'unlimited')

registerRateMax

SBC 5000:
1-100, or unlimited.

SBC 7000:
1-300, or unlimited

Maximum sustained egress rate of initial SIP registrations allowed on this zone. (default = 'unlimited')

You can set both “registerBurstMax” and “registerRateMax” as unlimited; however, if you assign a value to one parameter, the other must also be assigned a value.
