Can someone tell when I'm on another line using call waiting?

Will the caller hear a different type/length of ring when I'm on the phone with somone and a new caller "beeps in"?

If it is another Verizon cell phone caller, they will hear a tone after the "ring" (unless you use Ringback tones, then they will not hear any difference). Callers from a different carrier or a landlline will not have any indication that you are on another call,, as far as I know.
