Google failed me.


How do I dial a number with an extension?

Do I just dial

Number with #extension after it?

It's not one of those automated ones that says "please enter the extension number"
#2
just enter it when you call the number? that usually works for me
"We are not concerned with motive, with higher ethics. We are concerned only with cutting down crime-."

take original number. Take extension. count number of numbers in extension, most likely 4. Take 4 numbers away from original and replace them with the extension numbers. Et voila!
