Automatic dialing mode selection techniques are utilized in the operational environment of a telephonic device connected to a tip-ring line. The telephonic device includes dialing mode assessment circuitry and dialing mode setting circuitry. The dialing mode assessment circuitry automatically determines the dialing mode supported by the tip-ring line. The dialing mode setting circuitry is responsive to the dialing mode assessment circuitry for automatically setting the dialing mode of the telephonic device to specify the dialing mode supported by the tip-ring line, such as pulsed dialing or touch- tone dialing. The dialing mode is automatically set at the time that the telephonic device is first connected to the tip-ring line, and the telephonic device retains that mode setting until the device is removed from the tip-ring line.
