Note:

• Please check with your local telephone company to make sure that the access number that you are dialing is a local, toll-free call. 
• We assume no responsibility for local toll or long distance charges incurred for the use of our service.
• When you enter the access number, type it exactly as you would dial it from your home phone.
• Do not include a 1 or the area code unless you have to dial it to make a local call from your home telephone.
• If you are dialing from a hotel, office, or other phone system that requires you to dial a digit such as 9 to get an outside line, insert that number before the access number.
• To disable call waiting while using the Internet, insert the call waiting defeat code (usually *70) before the access number. Only insert this code if you have call waiting on the line you will connect with. Check with your phone company to determine the code to use for your line.
