Program That Tells You If Person Is on The other Line While Your Calling Them
a friend of mine has a imported phone unlocked gsm, that tells him when he is waiting for the other person to switch calls when the person is on the other line.
I have tried to search to see if there Is any programs similar to this?? that let you know if the person you are calling is on the other line at the time when you are ringin them?
some verizon phones you are able to tell by how the sound when ringing. but is there a physical program that tells you?
