VS 2010 Get Phone Number On Page - Reg Exp

Our company has an old intranet site, that has 1000's of pages, and ive created a loop to look at them all, but i wanted a way to put all the phone numbers it can find, into a text box, i have the code below but cant seem to get it to work.

Sometimes the phone numbers can be 111-222-3333 (111)-222-3333 111 222 3333

'Reg exp for phone number
Dim myMatch As Match = System.Text.RegularExpressions.Regex.Match(My_Text, "^([2-9]{3}-)?[2-9]{3}-d{4}$")

[Code]....
