Below is the sample AGI scrip written in per perl.
In This Script You will learn the following
1. How to write AGI concept.
2. Some Perl Programming.(Variables, Arithmetic Operator, IF/ELSE/ELSIF , comparision operators, Labels etc.
3. How to use mysql queries in AGI using perl.
4. Asterisk Application Used( NoOp, SayDigits, SayNumber, Channel Variables, SayUnixTimeStamp etc)
