Thanks for Kalen for contacting us with this project! Kalen writes:
The project was something I recently worked on after moving into a new apartment. I needed a way to allow guests into the building when I wasn’t always home. Since the buildings buzzer system was so old it only allowed for phones inside the unit to ring (with or without a landline). I decided to use a raspberry pi plus a USB modem to automatically answer the phone whenever someone buzzed the front entrance. The catch is the user must first visit my personal website and login to a web portal. After they’ve successfully logged in the nodejs app running on the raspberry pi will answer the call, dial 6, then hangup the call. After a predefined amount of time it will set a lock flag and stop answering the phone until someone has logged into the web portal again.
Hope you enjoy the project.
