    Evolution of the Telephone

  • Cradlestick

  • Cradle

  • Desktop Rotary

  • Touch Phone

    enabled calls to be switched digitally and allowed customers to dial numbers directly without operator assistance, replacing slower pulse-dialing technology and becoming the standard for telecommunication signaling worldwide.
  • Cordless

    cordless phone allows for wireless communication over a fixed landline connection by using a base station and a portable handset, enabling users to move freely within a limited range while talking on the phone. The base station, connected to the phone line, transmits signals to the handset via radio frequencies, and the handset sends the user's voice back to the base station.
