If I need to build IVR using Asterisk (so I will read and write to database), until now from my reading, I can understand that the best way is to use AGI to call external script like php which will manipulate every thing, correct?
Well, the returned values from this script that I can use it to route the call to the proper queue or Phone, how I can handle these returned values? Do I have to store it in the database? Well, how I will read it from database and use it in the extensions.conf?
From the other side, is there any tool to have IVR script (let us say, studio programing) that can be used in Asterisk? Any advise in this way?
