SIP Authentication Tracking
The controller supports the stateful tracking of session initiation protocol (SIP) authentication between a SIP
client and a SIP registry server. Upon successful registration, a user role is assigned to the SIP client (the default
role is guest). You specify a configured user role for the SIP client in the AAA profile.
