Ringing tone
 | This article needs additional citations for verification. (September 2010) |
A ringback tone is an audible indication that is heard on the telephone line by the caller while the phone they are calling is being wrung. It is normally a repeated tone, designed to assure the calling party that the called party's line is ringing, although the ring-back tone may be out of sync with the ringing signal.
The ringback tone (or "RBT") is in most cases generated in the distant switch and transmitted in-band. A message is also sent over the signaling system (usually SS7). In most public phone networks the tone is not generated in the handset or by the local switch, as customized tones or voice announcements may be generated by the distant switch in place of a ringing signal.
Ringback tone characteristics
United Kingdom, Ireland and some Commonwealth nations
In the UK, Republic of Ireland, Australia, New Zealand, and many Commonwealth nations, it is a double ring. For most countries, it consists of a 0.4-second pulse, a 0.2-second pause, a 0.4-second pulse, and a 2-second pause. In some countries, the pulse is made by mixing a 400 Hz and 450 Hz sine wave. This tone is featured at the end of Pink Floyd's "Another Brick in the Wall (Part 2)" and near the end of their song "Young Lust."
North America
In North America, the standard ringback tone is a repeating 2-second tone with a 4-second pause between. The tone is 440 Hz + 480 Hz.[1]
Europe (except UK & Ireland)
Most European countries, other than the UK and Ireland use tones which comply with European Telecommunications Standards Institute ETSI standards. All of these tones are 425Hz. Typically the pattern is 1 second of tone followed by 4 seconds of silence.
Ringback music
Also known as Caller tunes in some parts of the world (like India),[2] ringback music is a service offered by mobile network operators which enables subscribers to set music or even personalized recorded sounds as ringback tones.[3][4]
Early versions of personalized ringback tone systems have been invented by a couple of inventors, Mark Gregorek et al. (Patent Nr.5,321,740) and Neil Sleevi (Patent Nr.4,811,382).[citation needed] The first functional ringback tone replacement system has been invented by Karl Seelig et al. (Patents Nr.7,006,608 and Nr. 7,076,445). In 2001 Seelig's prototype was described in Orange County Register and the Economist Magazine kick starting the world wide development of ringback tone replacement.
Ringback advertising
Advertising over Ringback tones (AdRBT) was introduced using a range of models across several commercial markets in 2008. In America Ring Plus offered the first interactive advertisement platform. In Turkey, 4play Digital Workshop launched 'TonlaKazaan' AdRBT with Turkcell, and Xipto AdRBT launched in the United States with Cincinnati Bell wireless; OnMobile launched an Ad-supported Music RBT program in India with Vodafone. 4Play Digital workshop accumulated several hundred thousand users of their service in the first few months of commercial deployment, and received an innovation award in February 2009 at the Mobile World Congress in Barcelona. AdRBT typically rewards the caller or the called party with discounted Music RBT service, free minutes, cash, or other rewards in return for accepting advertising messages integrated with Music Ringback, or for selecting advertisements instead of music as a personalized advertising ringback.
A Juniper Research report released in January 2011 that predicts that Ringback Tone Advertising will reach $780 Million Annually by 2015.
Ringback patents
Patents for personalized ringback tone delivery systems were first filed in Korea by Kang-seok Kim (10-1999-0005344) and in the United States by Mark Gregorek et al. (Patent Nr.5,321,740) and Neil Sleevi (Patent Nr.4,811,382).[citation needed]
