Abstract
An architecture and technique for creating self-installable and portable telephony (dial tone) service that can be moved between any two locations that has access to both a voice communication network and a data network. A telephony adapter is used as a subscriber premises device that is connected between a conventional telephone set and both a voice network and a data network. A provisioning server communicates with the telephony adapter through the data network and maintains a record of the subscriber's local telephone number and IP address of the telephony adapter. As the subscriber moves from one location to another, the telephony adapter (once turned 'on') will communicate with the provisioning server and re-establish phone service, always using the same local phone number of the subscriber.
