TRANS and REAR ? and Push Button?

Hello All, I am Mike and new to Ring Community. Nice to meet you all. I am hoping some one can help me with these two questions. First Question. At my house, we have two doors, ̣̣Front and Rear. The time being, at the front door has an existing ring button, when it is pressed, it rings inside the house. Same thing for the Rear door. I only want to replace one door bell with the Doorbell Wired at the "Rear Door" - not the front door as i want to leave as it is - So, should I connect the Jumper Cable to TRANS and REAR positions ? Second Question: Does plastic push button on the Doorbell Wired always provide an audio ring on the actual device from a small speaker box at bottom, when the button is being pressed ? I appreciate for any answers you can give. Thank you in advance, Mike
