In this section:
The SBC 5110 and SBC 5210 hardware platforms are no longer supported beginning with the 10.0.0R0 release. This release supports SBC 5400/7000/SWe platforms. Contact Ribbon Sales for upgrade information.
IMPORTANT
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.
Note
As a best practice, always use UPPERCASE for trunk group names.
Note
Unless annotated otherwise, the parameter values in this section apply to the SBC Core.
Note
SIP subscription CAC limits are not applied to SUBSCRIBE requests from registered users in access deployments.

Command Parameters
SIP Trunk Group CAC Parameters

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) |
