Abstract

See full text

In a Voice over IP system, a user can dial numbers stored in a series of lists, which are stored in the system and displayed to the user of an IP telephone. One implementation will allow a user to scroll through a list of remote sites. When the user finds the desired site, the user is then presented with the same options as a user local to that site. All of this can be performed without the need for an operator or a printed directory. This system provides an ability for a user to scroll through a list of names and phone numbers and then call a person once their name and phone number is displayed.
