ABSTRACT:
A method and apparatus for providing multiple telephone lines using a single directory number. A method and apparatus for associating multiple directory numbers with multiple telephone lines. A broadband residential gateway (BRG) is a user interface to a broadband communication system providing packetized telephone service and other media services. The BRG has multiple ports, and each port is connected to one or more telephones. The multiple ports may be mapped to a single directory number, or the multiple ports may be mapped to multiple directory numbers. The BRG can provide greeting and message features. A greeting may instruct a caller to select a port which is associated with a party the caller is attempting to reach. Also, a message, played after the greeting, may further instruct the caller.
