Abstract
A phone call is selectively routed to a public switched telephone network or to a packet switched network based on a called number to which the phone call is directed. A phone call may be made as a Voice-Over-Internet-Protocol call through, for example, the Internet except when a user dials an emergency number, in which case the call is made to the public switched telephone network.
