Abstract

Direct Distance Dialing (DDD) access is provided for a communications services platform. A caller may dial a local DDD number or a long distance DDD number to access the communications services platform. A platform may provide a plurality of different communications services, including voicemail services, paging services, automatic routing services, and facsimile messaging services. Expenses associated with servicing the call are partitioned between a caller and a subscriber of the communications services platform in an intuitive and reasonable fashion.

Claims

1. In a telecommunications network for routing calls to a platforn that provides multiple communications services on behalf of a subscriber, a method comprising the steps of:

receiving it a local exchange carrier (LEC) switch, a call flow a caller that was initiated as a direct distance dialing (DDD) call by dialing a first DDD number;

translating, at the LEC switch, the first DDD number to a second DDD number;

routing the call from the LEC switch to an inter-exchange carrier(IEC) switch using the second DDD number and a special carrier identification code (CIC) generated by the LEC switch, the special CIC designating the call as one destined to a communications services platform;

sending a query message from the IEC switch to a data access point (DAP) based on the special CIC and the second DDD number;

receiving from the DAP at the IEC switch a translation of the second DDD number to a physical network address for the communications services platform; and

using said physical network address to redirect the call from the IEC switch to the communication services platform via an IEC network and an IEC bridging switch.

2. The method of claim 1 wherein the network includes a server holding a database of routing information, the IEC switch through which the call is routed accessing the database to obtain a network address for the platform for use in routing the call to the platform.

3. The method of claim 1 wherein said initiated call has a value unique to the subscriber.
