On a Verizon landline, what happens when you call your own number?

Question

I was recently vacationing at a rental house whose telephone company had this free service called home intercom. You would dial the number of your own house from within the house, hang up for a minute, and then all the phones would ring, that way you could talk to somebody in another part of the house. Does anybody know if Verizon has any kind of similar thing? I haven't tried dialing my own phone number, but was wondering what would happen.

Answer 1

You will get a busy signal. That service usually isnt available to residential phone customers.

Answer 2

On all land lines the when calling your own number it goes Busy tone. That is because when you call youself using the same phone, the connection is intrepided   because the loop is broken...  also.. cell phones dont have a loop so when you call yourself using your phone it goes to VoiceMail

That is also why you can get Call Waiting, because when you are on the phone with someone else, the call is in a Loop with You and the Other Person.
