Overview

To enable authenticated identity management, stiProfile is added and is associated to a SIP Trunk Group. If the state of the stiProfile attached to the ingress trunkgroup is enabled, the SBC sends STI related information to the PSX, which is provisioned to either sign, verify or tag the call. The SBC then receives information from the PSX about the service provided that is signing, verification or tagging

The provisioning on the PSX dictates whether STI related headers are signaled on the egress. 

The stiProfile has to be enabled on the egress sip trunkgroup for STI headers to be signaled on the egress.

For transparently passing Date Header, existing Header Transparency feature is used. When retryWithoutIdentity is configured for a SIP response code, on receipt of the response code the same route is tried without Identity Headers.

For the next route to be tried, the user provisions the reasonCode in the crankback profile. If the reasonCode is not provisioned in the crankback profile, the call fails.

Though these steps can be performed from either the EMA or from the CLI, the description below is limited to CLI.
