Doorbird and SIP

With Zanzito, will it allow me to see who presses the doorbell and have two-way communication?

I wanted something that is as easy as mounting a Doorbird or DP-104 into the side of the door and do the rest by adding the door station to Asterisk PBX myself, though.

And MQTT is brand new to me and I’ve never worked with MQTT in the past. I do not know of any devices out there that has MQTT built in.

I will see if I can find a 433MHz to MQTT gateway in Amazon, though, although I do not know if Amazon does have MQTT products.

Update: Uh, wait! There’s no such thing as MQTT gateway in Amazon’s website.

And by the way, can I not see this message?

Amazon.com is Amazon.com!
