question

I have it set up so that faxes to my toll free number are sent to my inbox. Whenever I get the email, it says "New Fax message from 123-456-7890". This works fine. However I have the fax number 123-456-7890 saved under a contact named John Doe, in the Business Fax field. So shouldn't it say "New Fax message from John Doe" instead?
