Welcome to the Zoom Community, @RickU.
By “our number,” I assume you mean your Main Company number, not a number assigned to you directly.
Check out this Zoom Support article on assigning access to voicemail left at other extensions, call queues, auto receptionists, etc.:

Without knowing your specific setup, I don’t know which section to point you to. If you are an Admin or Owner on the account, look on the Web Portal at Admin -> Phone System Management-> Logs and view the Viicemal & Videomail tab to see a list of all voice mail recordings by date, which includes the extension. Find this number in your Phone settings to see where you add the access.
