Set up chimes with 2 phone
You can indeed link multiple Ring devices to a Ring Chime or Chime Pro. After setting up your Ring Chime, visit your Video Doorbell in the Ring app (Main Menu > Devices > Video Doorbell). From the Video Doorbell device page tap on Linked Chimes.
Each of your Video Doorbells or Cameras will allow you to link to the same Chime for alert sounds and to Chime Pros for extending WiFI signal. I hope this helps!
