As some people already mention, August dialed a 3-digit number. To me it seems like the first number may have been 5, 6 or 7 & the other two digits could have been 11. In Wikipedia there’s an article about N11 numbers: http://en.wikipedia.org/wiki/N11_code. Now, could it be that the nuns have a side job as phone operators for traffic information (5-1-1)? Right now I don’t remember how they get their incomes apart form selling candles. But another thought is that if Jefferson is still in SB maybe he could have paid for a special 3-digit number.
