Call Waiting
Cost: $2.50 per month

If someone dials your number while you are using your telephone, a short tone will notify you of the call. The calling party will receive a normal ringing tone and cannot hear your conversation. If you desire, you can put the original party on hold by depressing the hookswitch for one second, and answer the incoming call. You may alternate between each call as often as necessary, but may not talk to both parties at the same time.
