Andrew,
When ever there is a problem you always look above and beyond then what the problem can really be. The reason for a busy signal was the modem was configured for a 1 before the phone number then I configured Addagio for a prefix of 1. So it was dialing 11(areaCode)phone number So having 2 number ones as a prefix does not work. So all is solved but as normal thank you for your support.
