Last I checked, Google Nest did not have a "Drop-in" feature like Echo where my parents can just drop-into the living room of the other house (no calling or ringing). The Echo device just makes a sound that someone is dropping-in and gives a 10 seconds heads-up (of course this only works if you enable the permission for family members. Else it's turned off by default).
