ABSTRACT:
A user interface is provided facilitating the entry of at least one destination phone number into a phone number dialing routine. Upon entry of the phone number, the user interface allows a Start command, causing the phone number to be dialed by transmitting appropriate signals to a switching exchange. In the event a charge code is required, the user interface provides for separate entry for charge codes. A controller concatenates the phone number and the charge code number with appropriate timing inserted to allow the switching exchange to utilize the number and charge code.
