One Number Needs to Ring to Multiple Phones

Both a call queue and shared line group would work in your case. If you want the ability to have user log out of receiving calls for that one number or if you're needing analytics, call queue is your best bet. 

hi @CPerry 

i agree with @sparrow that using a call queue would be your best bet.

zoom learning center has some very useful show me videos.  

these videos demonstrate how to set up your zoom phone system including the setup of your clinic's auto receptionist and call queue.
