Title: BRG with PBX capabilities

Abstract: A residential private branch exchange (PBX) allowing IP telephones, analog telephones and computers to connect to an IP communication network. A broadband residential gateway (BRG) PBX provides residences with multiple phone lines capability and the implementation of complex calling features traditionally associated with complex and expensive business PBX systems. The BRG PBX provides an open architecture interface minimizing problems during installation and operation, minimizes interoperability problems across multi-vendor equipment platforms and may provide customers with an option to bypass the local telephone company's high cost infrastructure. The BRG PBX may also provide a range of services from basic calling with few features to highly sophisticated calling features servicing multiple phone lines to the residence. The BRG PBX may be configured to connect multiple BRG PBX systems together in a Local Area Network (LAN) or Wide Area Network (WAN) configuration. These network configurations may be implemented to connect neighborhoods or families across multiple geographic regions. In addition to having the capability of connecting to each other, the BRG PBXs may be connected to IP Central Stations forming an IP communication network.

Claims

---

What is claimed is:

1. A method for providing calling services on a residential PBX, comprising the steps of: determining if an incoming call to a called number has a POTS address, and if so, converting the POTS address to an Internet Protocol address; determining whether the caller desires to access residential PBX calling features and if so, implementing the residential PBX calling features, otherwise routing the incoming call to the Internet Protocol address; determining if the called number has residential PBX calling features engaged, and if so, routing the incoming call according to the engaged residential PBX calling features; determining whether the caller has authorization to access the residential PBX calling features; rejecting the caller if the caller does not have authorization to access the residential PBX calling features; and allowing the rejected caller to enter another called number after attempting to g
