Using headphones as a microphone


A simple automatic dialing systems isn't very expensive or complicated to set up. You need four things to create a basic system:

A computer, preferably a desktop modelA voice modemAuto-dialing softwareAn active telephone lineA voice modem allows a computer to play or record audio over a telephone line. On a standard desktop computer, there's room for two to four internal modem cards. Each internal modem can only be connected to one phone line. So the more modems you have, the more phone calls the computer can make simultaneously.

If the auto-dialing system is going to be used in a call center with multiple live operators, then each operator will need his own telephone with a headset connected to a dedicated phone line. Autodialers can work over both the regular public switched telephone network (PSTN) or Voice over IP (VoIP).

The most important part of the auto-dialing system is the software. The software tells the computer which numbers to dial and how to respond to different situations (if an answering machine picks up, a human answers, a busy signal, et cetera).

Voice detection is the technology that allows auto-dialing software to detect the difference between an answering machine and a human voice. If the initial response is a short burst of words (one to three seconds) followed by a pause, then it's a human ("Dr. Johnson's office. sol republic tracks hd Predictive dialing is most useful in a call center setting, where multiple operators are making simultaneous calls. Predictive dialing technology uses a complicated algorithm to anticipate when an operator will be free to handle another call. Predictive dialing software analyzes several factors:

how many calls are answered by live peoplehow many calls are answered by machineshow many calls are never answered or encounter busy signalsthe length of a typical call when answered by a live personUsing this information, the predictive dialing software can calculate exactly how sol republic headphones often to start dialing a new number to maximize the amount of time the live operators are on the phone and talking. The system will often dial numbers when no operators are available, knowing that an operator is likely to end a call right when another one begins.

Interactive voice response (IVR) is an autodialing technology that supplies interactive menus on outgoing calls. For example, a marketing or demographics company can autodial consumers and present them with an interactive poll they can answer with their telephone keypad or voice responses.
