Caller Id

[deleted]

I understand caller id work with sound

when someone call the callerd is pick up this sound and convert to digit and show in caller id

in order to use vrs software we need a special device to see number

will may be able to descramble that sound and use as caller id and put the info as incomming call and show the number

Dual-tone-multi-frequency (DTMF) so it´s very easy to detect the sound of board.
