Use the Sti Profile window to view and configure Secure Telephone Identify (Sti) profiles to apply to SIP trunk groups. A Sti profile controls whether authenticated identity management is enabled for a trunk group. If the Sti profile is set to  enabled on an ingress trunk group, when the SBC receives an ingress INVITE request it sends STI-related information to the PSX. The PSX is provisioned to either sign, verify, or tag the related call. The SBC then receives information back from the PSX about the service it provided, that is, signing, verification, or tagging. Note that an Sti profile must be enabled on the egress SIP trunk group for egress signaling to contain STI-related headers. Refer to STIR-SHAKEN Support for more information.

To View Sti Profiles

On the SBC main screen, go to All > Profiles > Services > Sti Profile. The Sti Profile window opens.
