Fax Dialing Rules - Outlook Contact Fax Numbers

When I fax from my "Send Fax" wizard I choose a person from my Outlook contacts list ("Use Dialing Rules" box is checked), none of the Dialing Rules options seem to be able to make the fax dial a "1" before it dials the area code & phone number.

When I enter a tel or fax # in Outlook contacts by typing in the area code and number (xxx-xxx-xxxx) in the blank tel/fax field, it changes it immediately to the right form, (xxx) xxx-xxxx. BUT, it does not put the "+1" in front of the whole number to make it dial correctly when you choose this contact to fax with XP fax!! I have found that when I enter a fax or tel # in outlook contacts by clicking the button to show pop-up window where you enter the area code and tel # in separate fields, Outlook automatically puts a "+1" in front of the area code. THEN the XP fax dials correctly (1 + area code + fax #), even if dialing rules were not setup for that area code. I have a lot of cotacts with fax numbers already put in the first way I described above.
