Hello, I am novice in the field. I have a doorbell fon connected in my home phone. Can anyone provide a detailed way to have it ring my cell phone? Including what additional hardware I would need to buy? Thank you in advance.

Get a ring, skybell, nest door unit OR

Get a cordless phone unit with bluetooth to cell connectivity, maybe a 2 line one so you could isolate the doorbell fon unit from the first line and put it on the second for more flexibility.

Note: I've never waded into the bluetooth to cell connectivity and have let customers deal with it.

Does anyone make a smaller diameter camera/doorbell that may be a bit deeper? One of my customers has their doorbell button in a column, so depth is no problem, but it's a colonial house, and the others will look like shyte. Skybell is almost 3" diameter.
