jzwacki is right. Old telephone men are used to 9 selecting a piece of hardware that is connected to a trunk. All newer systems analyze the digit string, and then select the route. Most systems play dialtone after the trunk access digit (9), but it is system dialtone, not outside dialtone like the old days. Asterisk's outside dialing can be programmed without an access digit but it will really cut down your dial plan for other things like extensions. I suggest keeping the 9 as a leading digit on all outside calls. This will leave 1-8, and 0 available for extensions.
