I am new to Asterisk (I am using linux for quite some time and I have built my own linux desktop from scratch) . I have the following scenario :
I live in Germany and my parents live in India. At the moment when I want to call my parents, I use a Voip service provider account (dialnow.com) to call to my parents who has got normal PSTN telephone.
My question is :
Is it possible to use asterisk to become a voip service provider ? In other words what this Voip service provider is doing right now, I want to do it by myself. To start with I just want to call my parents (i.e. I want to call to any PSTN lines in this world), nothing else.
If this is possible, what hardware I require apart from the computer where I will install the asterisk ?
I have started reading the book (O’Reilly Definitive guide), but I didn’t get the answer.
