The learning curve in this area can be wicked complicated, if you don't have T1/ISDN background you may be in for a long tough haul if you try to write PRI call control yourself in C#.

You should probably start by refining your requirements statement, keeping it as technology neutral as possible. You need to be prepared to explain the business problem you are trying to solve clearly. E.g. if you need PRI, is it for connecting to the telephone sets, to the telephone company, or both. What actions happen when you "filter out" telephone numbers? Focus first on a clear statement of what, rather than how.

As to how, there used to be several companies that produced this sort of hardware/software packages, but over the years one of them (Dialogics) seems to have bought out most of the others hardware vendors, so a lot of the software vendors partner with them. I'd recommend you start at http://www.dialogics.com and look into solutions partners to see if you can find a close match for your requirements.

Good luck!
