The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The call admission control (CAC) Enhancement feature enhances the CAC mechanism to update the maximum number of incoming or outgoing connections for a dial peer and the bandwidth based on the media flow.
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release.

The CAC enhancement accounts for local call and bandwidth based on the media flowing locally or to the WAN side. In NanoCUBE call flows, if the media flows locally in NanoCUBE then the call is accounted as a local call and the maximum connections and bandwidth values are not updated. The local calls on NanoCUBE do not increment the count of the maximum connections counter.
Perform the following task to exempt local media calls and bandwidth from being updated on a dial peer.
1.
enable
2.
configure terminal
3.
dial-peer voice tag voip
4.
max-conn
number exempt-local-media
5.
session protocol sipv2
6.
max-bandwidth value exempt-local-media
7.
end
Perform this task to verify the configuration for the CAC enhancement. The show commands can be entered in any order.
1.
enable
2.
show dial-peer voice tag
3.
show dial-peer voice tag
