Abstract
A telephony system and method for providing telephony services to remote users. The telephony system comprises a user side and a provider side. The user side includes a telephony instrument and a personal computer for establishing communication with the provider side via a communication gateway, a communication device and a wide area network, such as the Internet. The provider side includes a virtual private network in communication with the wide area network and a communication network. The communication network is in communication with a telephony server interfacing with a telephone switched system. The telephone switched network provides telephone lines for allocation of the telephone lines by the virtual private network to the remote users.
Claims34
A communication system comprising:
- a first network;
- a second network;
- a first communication device providing communication between said first and second networks;
- a telephone switching system in communication with said first network and providing at least one communication line for allocation by said first network;
- wherein said first network allocates one or more of said at least one communication line for use by a communication instrument via said first communication device and said second network.
A method of providing a telephony service, said method comprising the steps of:
- receiving a request for said telephony service by a first communication device from a second communication device;
- communicating said request by said first communication device to a first network;
- providing at least one communication line by a telephone switching system to said first network;
- and
- allocating one or more of said at least one communication line by said first network in response to said request for said telephony service.
A method of providing telephony service, said method comprising the steps of:
- receiving a request for said telephony service for a first telephone number by a virtual private network via a first network;
- communicating said request by said virtual private network to a second network in communication with a telephony server;
- recording said request by said telephony server in communication with a telephone switching system, wherein said telephone switching system provides at least one communication line for allocation by said virtual private network;
- receiving a call on said first telephone number;
- retrieving said request by said telephony server;
- informing said virtual private network of said call by said telephony server;
- allocating one of said at least one communication line having a second telephone number by said virtual private network;
- and
- routing said call from said first telephone number to said second telephone number.
A method of providing telephony service, said method comprising the steps of:
- receiving a request for said telephony service for a first telephone number by a virtual private network via a first network;
- communicating said request by said virtual private network to a second network in communication with a telephony server in communication with a telephone switching system, wherein said telephone switching system provides at least one communication line for allocation by said virtual private network;
- receiving a call request;
- and
- allocating one or more of said at least one communication line by said virtual private network for said call.
A method of providing telephony service, said method comprising the steps of:
- receiving a request for said telephony service for a first telephone number via a first network by a gateway to a second network;
- communicating said request by said gateway to said second network in communication with a telephony server;
- and
- recording said request by said telephony server, said telephony server being in communication with a telephone switching system, wherein said telephone switching system provides at least one communication line for allocation by said gateway.
A business method comprising the steps of:
- providing a first network;
- providing a gateway in communication with said first network;
- providing a telephony server in communication with said first network;
- providing a telephone switching system in communication with said telephony server, said system providing at least one communication line for allocation by said gateway;
- and
- allowing a user to obtain telephony service on one or more of said at least one communication line via a second network.
