STIR/SHAKEN helps phone networks verify that caller ID information has not been spoofed in transit. Press 1 Voice can support authenticated calling workflows as part of a broader caller identity and reputation setup.
STIR/SHAKEN is a framework used by participating voice providers to authenticate caller ID information and help receiving networks evaluate whether the calling number was legitimately used.
STIR/SHAKEN helps authenticate the caller ID information attached to a call. It is intended to make caller ID spoofing harder and give receiving networks more information about the origin of a call.
The exact implementation depends on your voice provider and network path, but the basic process follows the same idea.
A participating originating provider creates a signed identity token for the call.
The provider includes information about the calling number and its level of confidence in the caller’s right to use it.
A terminating provider can validate the signature and use the result as one input when handling the call.
The attestation level indicates how much confidence the originating provider has in the caller’s identity and right to use the displayed number.
The provider knows the customer and has a high level of confidence that the customer is authorized to use the calling number.
The provider knows the customer, but may not have the same level of confidence that the customer controls the displayed calling number.
The provider is carrying the call into the network but has limited information about the caller or their right to use the number.
Authentication depends on your provider relationship, number ownership, and calling setup. A clean process makes it easier to maintain the right configuration.
