I need to block certain extensions from being able to dial long distance
Best way to do that is to sit down with the manual and look at programs 400-408. At a minimum, if you restrict 1 and 0 in a table and assign it to your extensons in 405, those phones can't dial long distance. That's fairly worthless in today's calling climate when some carriers let you dial just 10 digits or you have to dial 1 for any local call outside your area code. 404 lets you build 8 tables of 10 number sequences each for restriction and 407 lets you build 8 tables of 10 number sequences for allow. For example You could put 1 HOLD HOLD HOLD (hold is the wildcard) in one table and entry of 404 with traditional dialing and that would restrict all 1+ long distance. Then, in 407 5 of your entries in one table would be 1800, 1888, 1877, 1866 and 1855 to allow toll free calling. These tables get assigned to extensions in programs 405 and 408. A simple restriction (ie local calls only, internal calls only) get assigned in 401. There are some other tricks and, above all, remember that you have to keep 911 availabe for access and allowing 0 is never a good idea because 0 alone will get the operator and that defeats the purpose of toll restriction.
Other tricks involve custom CLASS codes. You need to account for the clever worker who dial *67. That gives them second dial tone and they can dial the world. It would be easy if you could block first digit *, but you ought to allow *57 for nuisance call trace. If you have the above where long distance is dialed with only 10 digits, then you can always start with HOLD HOLD HOLD in a table and allow 911 and the local area code in an allow table. The table digits can be up to 12 so you may have to go to 6 digit screening in allow tables for local exchanges. In my area, we have 10 digit dialing and 419352 419353 419354 (among others) along with 567213 are local calls. If I were programming a customer 6 miles to the North, there would be extensive programming in both area codes.
Outside of that, it's just a function of analyzing your local calls, area codes, how a call is dialed, and building your tables. We do this with billing by the hour :-)
