The name info that gets displayed is taken from the billing name/info of any phone originating a call. If both numbers are billed in 'YOUR NAME' (rather than the BUSINESS NAME) then that is what gets delivered as CID.
Is your business phone listed in your own name; or is it listed in the BUSINESS NAME? IS it in fact listed & billed as a business line --or is it improperly listed and billed as a 2nd residential line. SInce you indicate that both lines are in YOUR HOME, my guess is that you simply ordered 2 residential lines --and not the more expensive BUSINESS phone.
