I agree completly.
Why would you dislike customers ringing up for your service? your there to provide that service to them in the best approachable way whilst keeping the sale lead in the back burner. I really like the idea of having FAQ under the contact details - this could cut 'stupid calls' down alot - but if this was my business I would rather someone call me that have a quick flick through and move on to the next competitor site. If the calls get to much hire an telephone operator to take care of these - a moving business requires you and your employees to move with it..
Just my thoughts :)
