Ringing tone

<p>Ringing tone (audible ringing, also ringback tone) is a <a href="/facts/Signal_tone/j5Mo5Apv">signaling tone</a> in <a href="/facts/Telecommunication/vxoj1cxR">telecommunication</a> that is heard by the originator of a <a href="/facts/Telephone_call/4wUtUXpY">telephone call</a> while the destination <a href="/facts/Terminal_(telecommunication)/GTHNGWI5">terminal</a> is alerting the receiving party. The tone is typically a repeated cadence similar to a traditional <a href="/facts/Ringing_(telephony)/5sJ5G6wz">power ringing signal</a> (<i>ringtone</i>), but is usually not played synchronously. Various telecommunication groups, such as the <a href="/facts/Bell_System/GspEoeEF">Bell System</a> and the <a href="/facts/General_Post_Office/gnMB2RHN">General Post Office</a> (GPO) developed standards, in part taken over by the <a href="/facts/European_Telecommunications_Standards_Institute/8rJbbhPg">European Telecommunications Standards Institute</a> (ETSI) and other standards bodies. With modern <a href="/facts/Cell_phone/H3EcqD9h">cell phone</a> and <a href="/facts/Smartphone/cSIrBMWG">smartphone</a> technology ringing tone can be customized and even used for advertising.
