Is anyone on this newsgroup a caller-ID wizard?

I have a small business where I would like to display the caller ID
for incoming numbers (Name + Number) in a large format display in
front of my employees who will answer the phones and take orders from
incoming calls.

The employees will share a computer.   The main thing is I need some
software that will determine the geographical area (by area code and
exchange prefix) and display this before my employees answer the
phone.

Is there a stand alone box or display that will do this?  I've done
web searches for consumer units, but I haven't found one that quite
duplicates the lookup function.

If so, is there anything available in a larger format that doesn't
necessarily use a computer monitor?

I have multiple lines (4) and would like something that will work on
all four lines with 4 independent displays, but if necessary, I'll buy
four identical units.

Anyone know?   All ideas and suggestions appreciated...
