Abstract

The present invention allows a global telephone number be assigned to a first outbound-only telephone line connected to a first service switching point (SSP) to be also assigned to a second outbound-only telephone line connected to a second service switching point. The global telephone number can be used as many times as there are service switching points within a single area code region. In a preferred embodiment, in which an outbound-only telephone line subscriber also has a regular telephone line, all calls originated from the subscriber's outbound-only telephone line can be billed against the account of the subscriber's regular telephone line. The invention also allows multiple outbound-only telephone lines be billed against the account of a single regular telephone line. In addition, the invention also allows a subscriber of a regular telephone line that is used substantially or exclusively for outbound-only purposes to convert the regular telephone line into an outbound-only telephone line, thereby allowing the telephone number to reuse the global telephone number for an converted outbound-only telephone line.
