To gain access to an enhanced telecommunications service, security measures are put in place to verify the identity of a caller. In accordance with the invention, some of the security measures may be opted out by a user to expedite the service. In an illustrative embodiment, a user or his/her account is preliminarily identified by an automatic number identification (ANI) accompanying the call. The ANI indicates the number of the telephone from which the call originates. The user may elect the opt out if the originating telephone is believed to be secure from unauthorized users.
