Vista - Phone dialer is not dialing properly

Under the phone dialing properties i have my local area code just the way it was in XP but when dialing, the prefix area code get "truncated" by vista. See the example below;

When i dial 240-555-1234, the dialer tries to dial it as 1 2 555-1234, same thing for any other area code i attempt to dial.

I've searched and it seems to be a known issue but haven't found any solution yet...has anyone been able to solve this?

Have you contacted your ISP as to what number should be put in?

Frostmourne,
It doesn't really matter which number i enter as it still shrinks the area code. In addition I'm using broadband so no dial up connection.

anyone?!

I'm confused, if you're using broadband why do you need the dialer ?

I have a program (w/ its own contacts directory) that relies on the dialer rules/properties to initiate calls through a regular phone line.
