Abstract
A Session Initiation Protocol enabled network connected device receives a client certificate from a client device. The SIP enabled network connected device validates the client certificate from information received from a certificate authority. The SIP enabled network connected device determines an identifier of the client device from the client certificate. The SIP enabled network connected stores the identifier of the client device. The SIP enabled network connected device receives a SIP message from the client device. The SIP enabled network connected device inserts the identifier of the client device into the SIP message. The SIP enabled network connected device transmits the SIP message to a destination SIP enabled device after inserting the identifier of the client device into the SIP message.
