Is there really any requirement to make a website accessible if you could provide "full and equal enjoyment" via old fashioned phone support? I see this being vastly cheaper and less risky to provide for most non-"web app" websites (e.g. retail websites) for the smaller number of users who need it.

Edit: Found a source that seems to discuss it but it seems it hasn't been tested in court: https://www.adatitleiii.com/2017/10/telephone-access-might-b...
