Hi so I currently live in an apartment which has a buzzer that calls my home phone where I press 9 to let someone in. Soemtimes if someone forgets the keyfob and no one is home they are stuck waiting.
So I was thinking of using a VoIP system such as VoIP.ms and have it integrated into home Assistant so that when the lobby calls it can send a notification with which I can just allow it to open the door or any family member can. So far I am able to get home Assistant to detect when a number calls but not sure how to make it dial a key back to unlock the door.
