Express Dial is a phone dialer for Windows computers with a voice modem and headset. It can be used to automate the dialing of a list of numbers (as a predictive dialer) or to call single numbers when required using only your PC, modem and headset. Express Dial is designed to use a voice modem with a microphone and speaker jack. A headset is connected to these jacks and allows the user the hear the phone call and talk to the other party. You cannot use the normal telephone handset with Express Dial. Express Dial will use any voice modem connected to the PC's serial port so long as the modem has a headset connector or a mic and spk socket (most external modems do). In most cases it requires no setup. You can just install and dial immediately. One key use of Express Dial is for call centres and telephone surveys. Express Dial can be loaded with a list of phone number and it will sequentially call every number in the list. The user will choose when to end the call and automatically call the next number in sequence. This sequential calling can be started from the command line.
