CRBT is nothing but caller ring
back tone. It is a ringing tone heard by caller while doing call on the
telephone line. This Ring Back Tone is not generated in handset or by local
switch in public networks. In place of ringing signal, voice announcements
customized tones are generated by the distant switch. Ring Back Tones are also
called as Caller Ring Back Tones in some areas like India.
CRBT is a service
offered by the mobile network operators to the subscribers to set the music or
a song as a ring tone. Here we can also set personal recording sounds or songs
as a ring tone. You can also copy the ring tone which you heard while calling to
another person and set it as your ring tone. We can set CRBT on the basis of
time and geography.
