Environment  :  This article applies to Aruba Mobility Controllers part of VOIP deployments.


Call Admission Control (CAC) statistics are required only when “voip-cac-profile” is configured and enabled under virtual-ap profile of the ap-group”.  The VoIP CAC profile prevents any single AP from becoming congested with voice calls.




And below are the details of SIP status codes:


  • 480:  Temporary Unavailable
  • 486:  Busy Here
  • 503:  Service Unavailable


The values against the respective SIP status codes, help us to understand the availability of SIP service for the VOIP clients on the network.
