This page describes CLI syntax and parameters for the SIP Trunk Group 'Call Admission Control' object.
Use the SIP trunk group CAC parameters to configure call admission control (CAC) settings for a SIP trunk group on ingress, on egress, and as a whole.
...
|
As a best practice, always use UPPERCASE for trunk group names. |

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 the 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 the 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.
