R.T.B stands for remote telephone bell When your outside and you can't hear the telephone put the R.T.B outside and you will be able to know if its ringing or not. You can put the R.T.B ANYWERE Your house. How it works When the phone rings it sends a infared signal to the bell and then it starts ringing,you can also have lots of different ring tones.

Infrared wouldn't work for this; it's line-of-sight only.

Hmm. Apparently, IR does work around corners in Oz.  Must be the Coriolis effect.

How is this better than a cordless phone that not only rings, but you can answer it as well?

Sometimes people forget to carry it around with them and you could be upstairs with the door shut, and miss a very important call.

A cordless telephone will also have the same effect, if you don't answer it, but go in and pick up your regular telephone.

IR will bounce off an appropriately reflective surface.
