Abstract

The present disclosure describes providing an attestation level to a received communication. The attestation level may be used to communicate a level of security to a network or a called party that receives the communication. The attestation level associated with the communication may indicate to a destination network and/or recipient that the phone number associated with the communication is secure and/or the telephone number has not been spoofed. Determining the attestation level comprises comparing information associated with the communication with stored information and assigning a code based on the comparison. The code may be translated to a tag value that is used to direct the communication to a signing server for attesting the communication at the determined attestation level.
