Abstract

The present invention integrates Advanced Intelligent Network (AIN) and computer network technologies to provide telephone services. The system of the present invention comprises a gateway serving as an interface between a service control point (SCP) of an AIN and a computer network. The computer network is preferably the Internet. The SCP obtains call routing instructions from the subscriber of the present invention through a link during a communication session between the subscriber and the computer network. A trigger is provisioned on a subscriber'"'"'s line. When a call for a telephone line having the provisioned trigger is detected at a service switching point (SSP), a query is launched to the SCP. A call processing request query comprising calling party information is provided to the gateway. The gateway obtains a response from the computer network containing call processing instructions. The call is processed in accordance with the response.

17. The method of claim 11, further comprising the step of accessing a computer of the called party via the computer network.

18. The method of claim 17, further comprising the step of obtaining the response from the computer.

19. The method of claim 11, further comprising the step of processing the incoming communication in accordance with a default treatment if the response failed to be obtained.

20. The method of claim 19, wherein the default treatment is to terminate the incoming communication to the called party'"'"'s voice mailbox.

21. A system for managing a telephone call from a caller that is intended for a telephone line of a subscriber who is associated with a computer network and a computer, the system comprising:
