Abstract
Abstract An Internet Protocol Telephony Network and public switched telephone network, in which closed user groups may be dynamically defined and modified to take advantage of special billing within the closed user groups. Abbreviated dialing within the closed user groups may also be used to make dialing more convenient. The closed user groups may include members anywhere in a global network, and may take advantage of the special billing, regardless of whether the members are located in different states and/or countries.
