The Fad For Cellphones Is Ringback Tones

By Adam Pink

What are Ringback Tones?? Technically, a ringback tone is "an intermittent audible indication to the calling party that a dialed telephone number is ringing."? So what this is saying is that when you call someone you usually will hear a beep letting you know that you have been connected and the phone is ringing.

Another way to explain it is that it is a status indication that the number dialed is available (ie in service and not busy). This requires that the proper connections through the relevant telephony network or networks between the caller and the callee's audio devices are either made, or are available to be made, and the phone call will be connected if the call is picked up - either by an answering service or a person.

Once the receiving party has either answered your call, or you call was picked up by an answering machine or network voice service, the ringback tone stops. (awwww). The actual sound of a ringback tone will depend on your country and/or carrier.

Again, if we want to get technical, in North America (United States and Canada), which are within the North American Numbering Plan (NANP), the standard PSTN ringback tone is generated by summing a 440-Hz tone with a 480-Hz tone and applying these to the telephone line with 2 and 4 second alternating tones.

The interference due to the difference in frequency between the two tones causes a 40-Hz beat, and the tone combination produces the common warbling "ring ... ring ... ring" sound. The ringback tone may be generated by the switch serving either the called party or the calling party, but it is not generated by the called telephone instrument or PBX. Usually the ringback tone starts and stops at the same rate as the ringing tone of the called telephone, but generally is out of phase, i.e., one plays while the other is silent.

Now for the best part - instead of just hearing the standard ring when you call someone on their cellphone, the wireless companies have programmed things so that you can choose the sound that the caller hears when they call your cell. The most popular option for these 'ringback' tones are current popular music, although some general audio clips can also be selected. You choose the ringbacks you want on your phone through the subscription service you have with your cellphone carrier. Currently each ringback will have an associated charge on your cellphone bill.

Now here is the best part - you can completely customize the ringback tones that your callers hear. What's even cooler is that you can choose ringbacks to suit each individual caller. Generally, you can pick up to around 100 ringback tones at any given time. Each one of these can be setup so that each of your callers hear different ring back tones. The other method of setting them up is to choose a tone to suit the time of day. This is most often used so that callers hear a 'work hours' and a 'non-work hours' ringback tone.

Setting up ringback tones on your cellphone is as easy as doing a websearch for your cellphone carrier and 'ringback tones'.
