ABSTRACT:
An away from home calling service allows users to use telephones other than their home telephone as if they were using their home telephone. When traveling away from home, subscribers access the service and are prompted to provide authentication and validation information, as well as call completion information. The away-from-home calling service obtains the services provisioned on the subscriber's home telephone line and completes the call according to the subscriber's home services.
