all you need is a decent server, an good internet connection palabas (sa loob naman is IP based), and someone who can do it for you.
ang mahirap sa analog PABX is pag kailangan mo mag expand, ang mahal ng expansion cards.
I looked this up once... Sa dating study ko... Sa server.. Medyo sulit sya... If pc based softphones ang locals... Mabils mag expand... However kung hardware ip phones ang expansion... Challenge pa since wala pa asyado readily available na ip phone na mura...( havent found a contact in taiwan who can sell cheaper) If you use ordinary phone units naman, you have to get a adaptor... Then yung inbound calls din... Assuming na fr regular pldt lines (rj11 jack) ... Wala akong makitang modems that use a real hardware modem chip ( as opposed to a winmodem software modem) that is cheaper and more commonly available.... Sa presyo ng orig na digium cards.. Medyo mahal sa internet... And not sure where else makahanap ng alternative...
