Weird Dialing issue

[Sunfiregt]

I have my obi setup to do 7 digit dialing but there seems to be and issue when dialling a certain number. i have a number that is 444-4XXX and for some reason it will not go through... if I add the area code then it works fine.. however the number is not long distance and if i replicate the same thing using a mobile device it works ok...
