I'd like to know more about Restriction Tables in Unity. By default (in Unity 5 at least), there are some restriction rules set up to prevent a person to dial 9 and a string of digits (they seem to cover local through international dialing.) A couple of questions;
1) In the call patterns, I noticed the the "?" is used. Can someone help me understand what it signifies? Does this character mean "any character" that is part of the string?
2) What is a good test I can do to verify that toll fraud is being prevented? Is it enough to dial into the Greetings Administration and attempting to be transfered to an outside number?
Yes, this looks very good!
You are looking at this correctly for sure. The Transfer could come from a Caller Input key (logged in) or from the General Greeting where you are testing :) One thing that will make this "fool proof" is if you ensure that the CSS on your Voicemail ports is restricted to local calling only.
Hope this helps!
