A dialer (American English) or dialler (British English) is an electronic device or software that connects to a telephone line to monitor dialed numbers and automatically modify them for seamless access to services requiring long national or international access codes. It inserts or alters numbers based on the time of day, country, or area code, enabling users to connect through service providers offering the best rates. For example, it might use one provider for international calls and another for mobile networks. This technique is known as prefix insertion or least-cost routing. A line-powered dialer draws power directly from the telephone line, requiring no external source.
Another type of dialer is software that establishes an Internet or network connection over analog telephone lines or Integrated Services Digital Network (ISDN). Many operating systems include built-in dialers that use the Point-to-Point Protocol (PPP), such as WvDial.
