Abstract
The present disclosure describes techniques for verifying an identity of an originating device that initiates a VoIP communication with a recipient device. Specifically, an attestation parameter module is configured to detect a call request associated with a VoIP communication that is initiated by an originating device. The attestation parameter module may authenticate an identity of the originating device, and in doing so, insert an attestation parameter into an identity header of a modified SIP INVITE message sent to the recipient device. In response to receiving the modified SIP INVITE message with the attestation parameter, the telecommunication network associated with the recipient device may verify the identity of the originating device based on the attestation parameter included within the SIP INVITE message. In some examples, the attestation parameter module may generate and insert an attestation parameter within a modified SIP INVITE message that is initiated in a SIP/non-SIP telecommunication network.
