How do you make a call now?
Under Outbound Routes, you start making rules. Try _91Nxxxxxxxx as a pattern (1+10 digits) as a start. Strip 1 digit, pick your trunk, and that points you in the right direction. You need a class of service (National) and account for 911 and service codes. If you don't understand, hover over pattern with your mouse and the explanations of what the characters are.
