For off-net calls, you look at the external calling mask. It is available on the line, route patterns and the route list/route group configurations. The latter trumps the former. Translation patterns can also be used.
For on-net, then you would use translation patterns.
Those are where you can start. Post back if you need further clarification.
If you look at the line, route pattern, route group within route list, gateway and translation configuration pages, you will see a section called Calling Party Transformations. You can use these fields to mask the DNIS to display whatever you want. Your PSTN carrier may place restrictions on this however.
If you fill out the line configuration page with 512-555-1111, and this field has not been populated on any of the upstream configurations, i.e. route pattern, then route group config in route list, etc, then 512-555-1111 will be sent out. I believe you have to check "use calling party external number mask" or something like that.
