Who I have the same questioned this topic

   I have a personal phone I carry with me everywhere I go.  I want to add a new business line for my business.  I do not want to carry 2 phones.  I was thinking of adding a new business line, and forwarding the business line to my personal phone so I can get both business & personal calls on a single phone.

HOWEVER,

  I need a way to distinguish which calls are coming through the business line vs which are coming through my personal line.  That way I can answer the phone differently depending on the call.  What I need, is a special ringtone that is only used when calls are forwarded from my business line.

   Doesn't this seem like a great idea???  Perfectly logical...  but as far as I can tell, this is not an option.  Does anyone know if this is possible?  If not possible, this really should be added as a new feature.  It would be a huge help to verizon customers who have businesses.  Carrying two phones everywhere is completely ridiculous.
