Method of billing in an abbreviated dialing service
摘要:
A telecommunications service translates an abbreviated dialing code into a toll free number, routes the call to an interexchange carrier, and manages the billing associated with the call. A billing system processes the billing such that a subscriber of the abbreviated dialing code service is billed for the call rather than a calling party.
