As stated in a prior post the FCC is working on this with it's Robocalling Strike Force, I agree that Hiya is not a perfect solution it does however limit the exposure for the time being until the additional solutions can be worked into the infrastructure.

STIR (Secure Telephony Identity Revisited) is the standard developed by IETF that defines a signature to verify the calling number, and specifies how it will be transported in SIP “on the wire” whereas SHAKEN (Signature-based Handling of Asserted information using toKENs) is the framework document developed by ATIS/SIP Forum IP-NNI task force to provide an implementation profile for service providers implementing STIR. SHAKEN/STIR will be the basis for verifying calls, classifying calls and facilitating the ability to trust the caller ID information. However, the full benefits of this standard will only be realized on networks that have been fully transitioned to IP and will offer limited or no mitigation for calls that either originate or terminate on the PSTN.
