Confused About The New Ringback Tones?
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.
Technically, your ringback tone is a status indicator telling your caller that your line is available (ie., in service and not busy). Network connections through the telephony networks between the caller and the callee's audio devices are either made, or will be available to be connected, and the phone call will complete.
If all goes well, then the call can either be answered by a person (as long as the called number is not busy, or if the number is busy, and the phone being called has a call waiting service which notifies the person occupying the line to hang up the call in process, or put it on hold, in order to answer the incoming call), or by an answering machine or a network-based voice processor. This is the default case if the line is busy and the user a) doesn't have a call waiting service, or b) did not answer the incoming call within the (programmable) number of rings.
So for the audiophiles among us, 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 - on for two seconds, off for four seconds.
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.
You can customize the tone played depending on the caller - it is possible to select up to 100 or so active ringback tones at any given time, each programmed so that different callers hear different tones/songs/clips, or programmed so that different tones will play dependent on the time of day.
