HI, As a hobby project I would like to build a digital PABX using asterisk and a Safaricom line. I have a spare computer that I would like to use for this purpose. Has anyone done this before? I need pointers specifically on how to build the interface between the SIM card, computer and my small network at home. What hardware did you use to hold the SIM card and does it have a standard ethernet port to connect it to my 'digital PABX'? My end objective is to have the set up this way: Incoming calls -> Asterisk box -> Calls routed to softphones installed on the computers -> Me receiving calls and saying "M.G customer care. How may I help you" -> Impress family , friends and the Mrs(Designate) and eventually earn the grand title of 'Immortal Family Geek'(IFG) -> Live to be 140 and then die happy having lived a fulfilling life! :) I would be keen on spending as little money as possible seeing as this is just a fun project for me to explore the world of Asterisk/Open-Source Digital PABXs. -- Kind Regards, Moses M.G.
