Command Parameters
| Caption | ||||
|---|---|---|---|---|
| ||||
Parameter | Length/Range | Description | ||
|---|---|---|---|---|
| 1-23 | The name of the zone. You can configure signaling, media, and control for a zone in the address context.
| ||
cac | N/A | Call Admission Control (CAC) parameters for all peers using this zone. | ||
bandwidthLimit | 0-2147483647, or unlimited | Total bandwidth limit in Kbps/sec. | ||
bandwidthLimitThreshold | 0-100 | Bandwidth utilization notification threshold, as a percentage. (default = 0) | ||
bandwidthVideoThreshold | 0-100 | 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) | ||
callLimit | 0-2147483647, or unlimited | Total number of calls allowed on this zone. (default = 'unlimited') | ||
callLimitThreshold | 0-100 | Call limit utilization notification threshold, as a percentage. (default = 0) | ||
egress | N/A | Egress-specific call admission control configuration. See Egress Parameters table below for details. | ||
emergencyOversubscription | 0-1000, or unlimited | This 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) | ||
extendedEmergencyIpLimit | 0-40000 | Additional number of emergency calls (expressed as a numeric value) allowed if call limit and emergency over-subscription quota are exhausted. (default = 0) | ||
hpcOversubscription | 0-100 | This 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) | ||
| N/A | Ingress-specific call admission control configuration. See Ingress Parameters table below for details. | ||
registrationLimit | 0-2147483647, or unlimited | The number of concurrent registrations allowed in this zone. (default = 'unlimited') |
