1	SIP Trunk Group CAC Parameters

Parameter	Length/Range	Description
`bandwidthLimit`	0-2147483647, or unlimited	The total media bandwidth limit, in Kbits/sec. (default = "unlimited")
`bandwidthLimitThreshold`	0-100	Enter threshold value (as a percentage) to specify bandwidth utilization notification threshold. (range: 0-100 / 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. (range: 0-100 / default = 0)
`callLimit`	0-2147483647, or unlimited	Total number of concurrent calls (either ingress or egress) allowed. (default = “unlimited”).
`callLimitThreshold`	0-100	Call Limit utilization notification threshold, as a percentage. (default = 0)
`egress`	N/A	Egress-specific call admission control configuration for the SIP trunk group. See Egress Parameters table below for details.
`emergencyOversubscription`	0-1000	The percentage of resource oversubscription allowed for emergency calls. (default = 10)
`estimatedChildRegistrations`	1-256	Estimated number of child registrations (i.e. the estimated number of P-Associated-URIs in 200 OK message). (default = 1)
`extendedEmergencyIpLimit`	0-40000	The resource oversubscription (expressed as numeric value) allowed for emergency calls. (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)
`ingress`	N/A	Ingress-specific call admission control configuration for the SIP trunk group. See Ingress Parameters table below for details.
`registeredEndpointCacProfile`	N/A	`<SIP CAC Profile Name>` – The name of the SIP CAC Profile (containing endpoint CAC parameters that are applied individually to each registered peer) to associate with this trunk group.
`registrationLimit`	0-2147483647, or unlimited	The total number of concurrent SIP registrations allowed. (default is 'unlimited')
`subscriptionLimit`	0-2147483647, or unlimited	The total number of concurrent SIP subscriptions allowed on IP trunk group. (default is 'unlimited')
`tcpMediaLimit`	0-5000, or unlimited	MRM session limit per trunk group.
`unRegisteredEndpointCacProfile`	N/A	`<SIP CAC Profile name>` – The name of the SIP CAC profile (containing endpoint CAC parameters that are applied individually to each unregistered peer) to associate with this trunk group. (Refer to SIP CAC Profile - CLI for profile details.)

Parameter	Length/Range	Description
`callBurstMax`	SBC 5000: 1-900, or unlimited SBC 7000: 1-2700, or unlimited	Maximum allowed burst size (above the allowed sustained rate) for egress call attempts, in calls per second. (default = 'unlimited')
