System and method for accessing a messaging service using a short dialing sequence
First Claim
1. A system for enabling a user to access to a voicemail service comprising:
- a customer premises equipment (CPE) at a user location for use by a user, the CPE comprising a plurality of character keys for use in dialing a sequence of characters; and
a central office switch in communication with the CPE, the central office switch comprising;
a supplementary service processor operative to receive the sequence of characters from the CPE, generate a query to a supplementary service database when the sequence of characters is a predetermined n-character messaging sequence where n<
7, and receive a call forwarding number from the supplementary service database;
wherein the central office switch is operative to connect the CPE with a voicemail service in response to the call forwarding number; and
wherein the supplementary service database is operative to determine whether the central office switch supports a supplementary service by analyzing the predetermined n-character messaging sequence to determine if a service code is present, determine whether the user has access to the voicemail service using a caller identifier, and transmit the call forwarding number to the central office switch if the central office switch supports a supplementary service and the user has access to the voicemail service.

Abstract
A system and method for providing easy access to messaging services in a telecommunications network having office switches that are used by different providers of telephone and messaging services. The system uses a supplementary services database to maintain customer records including whether the customer uses messaging services and whether the customer subscribes to a short dialing sequence service for access to the messaging services. The customer is connected to the central office switch, which analyzes the dialing sequences generated by the customer. When the customer attempts access to the messaging services, the customer dials a short dialing or message sequence, such as *XX. The central office switch triggers a query to the supplementary services database for a call forwarding number to the messaging service used by the customer when the selected short dialing sequence is recognized by the switch. When the central office switch receives the call forwarding number, the number is used to route the customer to the messaging service.
