Nutone 105N transformer with Nutone speaker doorbell...compatibility with Nest Video doorbell

I have a Nutone doorbell with a speaker instead of traditional plunger and chimes. I would like to connect a Nest video doorbell to replace my front doorbell.  It is powered by a 105N transformer that is a 16 volt (15 volt amps at the doorbell speaker).  Is this compatible with the Nest and how is it wired?  I have two incoming wires, one yellow and one green.  The yellow has a bell wire connection to the green wire (wire nut) and the green wire has two bell wire connections, one to the side door and one to the front door.  How do I connect the two wires from the Nest?  One surely will connect to the front door connection and the other to where?  Will this be a problem since I have a speaker for my chimes instead of a typical plunger?  Is there enough voltage?
