Ringback tone

In a ringback tone (also known as Personal dial tone, ring back tone, ring -up tone, sound logo or musical ring tone (MFT ) refers ) is a feature of the telephone network, in which a caller in the ringing phase (ie until has the called party or answering machine answered the call) gets parallel to the ring tone music to listen to.

In Germany this ( paid ) feature is available since early 2004 in the mobile network of T -Mobile and Vodafone and is available since the end of 2005, fixed-line customers of Deutsche Telekom available.

The customer can choose the ring back tone from a larger number of tracks available, and assign all or only certain callers caller groups.

Since there is a line-side feature, function ringback tones with all phones. Unlike eg ringtones here the piece of music is not downloaded to the device, but mixed by special network elements of the ring tone - in-band signaling.

In the course of further development of this product are now offering some providers also the so-called video ringback tone.
