Abstract
Novel tools and techniques for providing enhanced services to telephone subscribers with multiple telephone lines, which can include one or more traditional telephone lines, wireless telephone lines, Internet protocol-based telephone lines, and/or the like. For example, certain tools can provide a subscriber with a unified voice mailbox for a plurality of the subscriber's telephone lines. In some cases, the subscriber does not need to check multiple voice mailboxes (each associated with one of the subscriber's telephone numbers) in order to ensure that the subscriber has received all messages intended for that subscriber. Instead, any incoming call on any of the subscriber's lines can be routed to a converged voice mailbox for easy retrieval by the subscriber of all messages from one location. Some tools employ a VoIP switch to handle routing of the incoming call to the correct voice mailbox.
