I'm finally releasing this.
We've always been told this couldn't be done but I've found that one of the features of the 3300 can allow us to do it.
So here's the doc.
How to stop specific callers from being able to dial in.
You can download the PDF herePlease use this forum for comments and to ask question. I cannot answer PM questions.
Some notes:
1) It's complex. If you're not an experienced tech then you may want to enlist the help of more senior individuals.
2) Don't try to program it during busy hours. If you make a mistake it will cause all calls to fail. Do it during a slow time to give you time to test & debug.
3) This only works for SIP trunks and Euro ISDN.
4) This may cause Anonymous calls to fail. So far I haven't found a way around this. Please let me know if you do.
