Some people will not want to call long distance. If he has a local office, better add that phone number.
If he doesnt you might consider adding that toll free number going around. The one paid for by the amnesty activists.

I tried to call Lott’s office Friday afternoon for a couple of hours. The phone just rang and no one answered.
