Abstract
In one embodiment, a telephone service method that provides subscribers with the functionality of an extra telephone line during data/Internet sessions is disclosed. Each subscriber has a unique telephone number Dns that can be dialed by anyone with access to the PSTN. When the Dns is dialed the call will be routed via the PSTN to the ILTD server. The ILTD server upon receiving the call attempt from the Dnc will analyze the dialed number (Dns) and determine if the subscriber's computer is able to receive the telephone call. If the subscriber's computer is actively engaged in an Internet Protocol session, with the ILTD client software running, the ILTD server will connect the call over the Internet to the ILTD client software.
Claims20
A computer-implemented method comprising the following operations performed by one or more processors:
- receiving, at a call routing device, a call to a subscriber direct inward dial number hosted on the call routing device, the call routed to the call routing device from a circuit switched network based on the subscriber direct inward dial number;
- identifying, by the call routing device, the subscriber based on the subscriber direct inward dial number;
- identifying, by the call routing device, an Internet Protocol (IP) address registered for the subscriber;
- sending, by the call routing device, one or more data packets representing an incoming call message to the Internet Protocol (IP) address;
- receiving, by the call routing device, a response to the incoming call message;
- and
- performing one or more call processing functions based on the response.
A non-transitory computer-readable medium storing a set of instructions which, when executed by at least one processor, cause the at least one processor to perform the following steps:
- receiving, at a call routing device, a call to a subscriber direct inward dial number hosted on the call routing device, the call routed to the call routing device from a circuit switched network based on the subscriber direct inward dial number;
- identifying, by the call routing device, the subscriber based on the subscriber direct inward dial number;
- identifying, by the call routing device, an Internet Protocol (IP) address registered for the subscriber;
- sending one or more data packets representing an incoming call message to the Internet Protocol (IP) address;
- receiving a response to the incoming call message;
- and
- performing one or more call processing functions based on the response.
A call routing device comprising:
- one or more processors;
- and
- at least one computer-readable storage medium storing (i) information indicating an assignment of a subscriber to one of a set of direct inward dials to place and receive calls and (ii) a set of instructions which, when executed by the one or more processors, cause the one or more processors to perform the following steps:
- receiving, at a call routing device, a call to a subscriber direct inward dial number hosted on the call routing device, the call routed to the call routing device from a circuit switched network based on the subscriber direct inward dial number;
- identifying, by the call routing device, the subscriber based on the subscriber direct inward dial number;
- identifying, by the call routing device, an Internet Protocol (IP) address registered for the subscriber;
- sending one or more data packets representing an incoming call message to the Internet Protocol (IP) address;
- receiving a response to the incoming call message;
- and
- performing one or more call processing functions based on the response.
