In this section:
The SBC 5100, SBC 5110, SBC 5200, and SBC 5210 platforms are no longer supported beginning with the SBC Core 10.0.0R0 release. This release supports SBC 5400/7000/SWe platforms. Contact Ribbon Sales for upgrade information.
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.
Unless annotated otherwise, the parameter values in this section apply to the SBC Core.
SIP subscription CAC limits are not applied to SUBSCRIBE requests from registered users in access deployments.

Call policing using callRateMax
and callBurstMax
is applicable only to normal and emergency calls, not to high priority calls (HPC).
