I am a fresher to asterisk. I got asterisk installed in my system. I am going through the book Asterisk the future of internet telephony and doin the instructions step by step. I needed to know the minimum hardware requirement to configure a call i have 3 systems which run on fedora core 6 running on Kernal 2.6. Could any please let me know how to configure a soft phone through which i can place call. i am right now exploring IP only configuration. All the 3 systems are connected in an intranet. How could i place calls between 2 of these systems?
