I installed 3cx and it is much better than I anticipated. I previously had an SPA9000 that was not always reliable. Anyway, I have 2 spa922 and a cisco 7940. The spa922's I have functioning dial plans that auto add a "1" in front of a number that I dial. Dialing 1 + area code + number is rather annoying. How would I set up a dial plan for the 7940 to auto add a 1 in front of the number dialed?? Thanks.
