Hi Antony. Good Morning. Thanks for your reply. I am a Novice in Asterisk Programming but have 15 years of experience in automating Ms Office tools using VBA. I am VBA Developer basically. We do automate Excel and Word and other office tools. I clearly know what is computer and how it works and all. But I don’t posses a good amount of Knowledge networking, Hardware and other things. But learning to program an IVR is a dream project of mine. Yes. I have been trying it for more than15 years but not entirely consistent on Asterisk. Very recently only I have known this book. But the from the starting itself its daunting to achieve what the author has communicated. Either one thing or the other is not perfectly getting installed as the author intended us to… Still confused. Please Help.
