Buzz Me In! acts as your personal concierge/doorman. If you live in a secured-access building, Buzz Me In provisions you a dedicated phone number to use with your building's Call Box. When visitors need entry, the Call Box calls your Buzz Me In number (instead of your cell phone), and prompts the visitor to enter a 4-digit access code. If they don't have/know their access code, Buzz Me In will forward the call to your cell number, connecting the visitor to you only when absolutely necessary!You define any number of access codes and when they're available. Create access codes for friends, family, the dog walker, babysitter, deliveries, or whatever your needs may be.Coming in Q2 of 2016:If you live in a house with a garage door opener, soon Buzz Me in will also support access codes for your garage!
