Abstract (en)
[origin: WO2019028058A1] Communication systems can include a first device located near an entryway of a building and additional devices located inside the building. Communication systems can enable people to communication via the devices and can also enable people located away from the building to communicate. Communication systems can enable a visitor who is seeking a person (that the visitor may think is inside the building) to communicate with the person even though the person is located away from the building.
