Read a number from the caller and run an AGI script using it as parameter

Let's make the example of a service to verify if a code provided by the user is valid or not, by checking in a database.

Let's define an AGI script to test if the code is good or not. We'll send the number entered as parameter. As an additional parameter, we'll send the callerid number of the caller

Then we can create the custom destination to use the AGI script defined
