VOIP providing call forwarding to external phone network

Abstract

System and method of forwarding a caller's request for a Voice over IP (VoIP) call to another phone network using the callee's phone number if the callee's VoIP account is offline. The call request is forwarded after the VoIP system determines that the callee VoIP account is currently offline. In this manner, a voice communication can still be established through the phone network despite the callee being unavailable for a VoIP call. The callee's phone number may be explicitly contained in the VoIP user ID or stored in the VoIP database and associated with the user ID. The forwarding process is transparent to the caller.

AI Technical Summary

Benefits of technology

The patent presents a Voice over IP (VoIP) system that improves user experience by increasing the chance of one user reaching another for voice communications. The system automatically forwards a VoIP call request to a regular phone if the calle is offline. The regular phone can act as an external VoIP account, and the system uses the callee's regular phone number as the ID for accessing the VoIP system. This facilitates transparent call forwarding without adding roaming fees. The system also reduces the average cost of voice communications by prioritizing VoIP communication.

Problems solved by technology

A major cause for frustration in using VoIP is that a user account (especially a callee) often stays logged out or offline so the caller cannot reach the callee, for example while the VoIP application program is closed on the callee's IP phone, the callee's IP phone is shut down or has no access to WiFi or any other network service, and etc.
