Is it possible to make a wireless door-phone doorbell with Arduino?

Here is the thing, i want to make a doorbell that lets me answer the door from the inside wirelessly. I would be like: -Push button on street. -Alarm sounds inside. -Press a button inside that would allow to communicate with the outside unit (like answering a phone, a live conversation). -Release button to finish the "conversation mode". All of this would have to be wireless, is this possible? would i need anything in particular? I tried searching on google but all i find are simple doorbells and "smart" ones that send notifications to your phone.

Well, yes, I think it was a device from NSA ... they called it... wait ... yes, there it is: "THE BABYPHONE". But don't search for it online, it's mostly classified and you will land on THE list ...
