Hardwired ring doorbell is charging but not activating chime

My ring doorbell is hardwired to a 22V mechanical doorchime. Ring settings show it as being hardwired, and it is getting a tricklecharge (and never requires a usb charge). However the mechanical chime does not get activated when the ring button is pressed. When I remove the ring device and jumper the contacts the mechanical chime rings as expected. Thoughts?
