February 17, Large central offices used motor-driven generator sets for both ringing and other signals such as dial tone and busy signals. In smaller offices, special sub-cycle  magnetic oscillators were used. Typically, solid-state oscillators have replaced them. Originally this voltage was used to trigger an electromagnet to ring a bell installed inside the telephone, or in a nearby mounted ringer box.
Fixed phones of the late 20th century and later detect this ringing current voltage and trigger a warbling tone electronically. Mobile phones have been fully digital since the early s second-generation "2G" devices, hence are signaled to ring as part of the protocol they use to communicate with the cell base stations. While the sound produced is still called a "ring",  more-recently manufactured telephones electronically produce a warbling, chirping , or other sound. Variation of the ring signal can be used to indicate characteristics of incoming calls.
For example, ringing bursts with a shorter interval between them might be used to signal a call from a given number. In POTS switching systems, ringing is said to be "tripped" when the impedance of the line reduces to about ohms when the telephone handset is lifted off the switch-hook.

This signals that the telephone call has been answered, and the telephone exchange immediately removes the ringing signal from the line and connects the call. This is the source of the name of the problem called "ring-trip" or "pre-trip", which occurs when the ringing signal on the line encounters excessively low resistance between the conductors, which trips the ring before the subscriber's actual telephone has a chance to ring for more than a very short time ; this is common with wet connections and improperly installed lines.
The ringing pattern is known as ring cadence. This only applies to POTS fixed phones, where the high voltage ring signal is switched on and off to create the ringing pattern. In North America, the standard ring cadence is "", or two seconds of ringing followed by four seconds of silence.
In Australia and the UK, the standard ring cadence is ms on, ms off, ms on, ms off. These patterns may vary from region to region, and other patterns are used in different countries around the world.

Some central offices offer distinctive ring to identify which of multiple numbers on the same line is being called, a pattern once widely used on party line telephony. In many systems, including North America Bellcore standards, Caller ID signals are sent during the silent interval between the first and second bursts of the ringing signals. The caller is informed about the progress of the call by the audible ringing signal, often called ringback tone.
Power ringing and audible ringing are not synchronized. These gongs provided "distinctive tones" for hearing-impaired customers and also made it possible to distinguish the specific telephone that was ringing when several telephones were placed in close proximity. While rings, ringers, ring signals, or what might be viewed as the call signals which are the predecessors of ringtones, date back to the beginnings of telephony, modern ringtones appeared in the s and have expanded into tunes and many customizable tones or melodies.

Following a FCC ruling which permitted third-party devices to be connected to phone lines, manufacturers produced accessory telephone ringers which rang with electronic tones or melodies rather than mechanical bells. People also made their own ringers which used the chip from a musical greeting card to play a melody on the arrival of a call. Some of these ringers produced a single tone, but others produced a sequence of two or three tones or a musical melody.
It was the first mobile phone where a user could input an original melody, rather than the preset songs. These phones proved to be popular in Japan: The first downloadable mobile ring tone service was created and delivered in Finland in when Radiolinja a Finnish mobile operator now known as Elisa started their service called Harmonium, invented by Vesa-Matti Pananen.
A ring tone maker is an application that converts a user chosen song or other audio file for use as a ringtone of a mobile phone. The ringtone file is installed in the mobile phone either by direct cable connection, Bluetooth, text messaging, or e-mail. Many websites also let users create ring tones from digital music or audio. The earliest ringtone maker was Harmonium, developed by Vesa-Matti Paananen, a Finnish computer programmer, and released in for use with Nokia smart messaging.
In , Clarke registered ringtone. These often use encoding formats only available to one particular phone model or brand. Other formats, such as MIDI or MP3, are often supported; they must be downloaded to the phone before they can be used as a normal ring tone. When someone buys a ringtone, an aggregator a company that sells ringtones either creates the tune or mixes a pre-existing tune.
