    • 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.
    • 本发明允许将全局电话号码分配给连接到第一服务交换点(SSP)的第一出站电话线路,以将其分配给连接到第二服务交换点的第二出站电话线路。 全球电话号码可以与单个区域代码区域内的服务切换点一样使用多次。 在一个优选实施例中,只有出站的电话线路用户也具有普通的电话线路,所以从订户的仅出站电话线路发出的所有呼叫都可以针对用户的常规电话线路的帐户来计费。 本发明还允许针对单个常规电话线的帐户来计费多个出站电话线路。 此外,本发明还允许普通电话线的用户基本上或排他地用于出站唯一目的,以将普通电话线转换成仅出站的电话线,从而允许电话号码重新使用全球电话号码 用于转换出站的电话线路。
