Abstract
The invention relates to methods and apparatus for wireless multi-site networking using signaling and voice over Internet protocol. The apparatus includes a wireless portable terminal, a controller for controlling communications equipment, wireless base stations, a computer network, and signaling devices. The wireless portable terminal is registered to a home controller when within a home coverage area, and the wireless portable terminal is registered with a remote controller when within a remote coverage area, thereby allowing the wireless portable terminal to roam from the home location to the remote location using a home wireless base station and remote wireless base stations, respectively, with the ability to make and receive calls via its home directory number.
