Zoom phone for both my business and personal numbers

[Headmuck]

I have a zoom account with both Zoom Workspace and Zoom phone.  I use the phone for my business.  I want to port my xfinity personal phone number (a landline !) to Zoom.    It looks like I don't need another Phone License to do this, but I can just add another number to the existing phone license I have.  Is that right?  If I have unlimited US/CA on the business phone, and I just add another number to that license (by home number), does the home number inherit the unlimited US/CA as well?  Lastly, if I just add a number to the existing license, can I route business calls to my zoom app on my cell phone, route personal calls to both my cell and my wife's cell as well as a sip phone?   Or do do this, i need another phone license.  Thanks for the help.  Couldn't reach zoom support or sales to get this answer.
