  • receiving a call from a calling party at an authentication site;

    determining at the authentication site if the calling party is authorized to access the service facility;

    disconnecting the calling party from the authentication site and re-connecting the calling party to the service facility using a call set-up signaling message containing an encoded string in a field not generally used for call control purposes, if the calling party is authorized;

    sending a security message containing a correlate of the encoded string to the service facility through a parallel network, if the calling party is authorized; and

    correlating the security message with the call using the encoded string and the correlate of the encoded string prior to permitting access to the service at the service facility.
