My aim is to have free call while I am in or outside office
I want my colleague can call me from office analog phone while I am outside or
My client in US HK can call me using local number.
Their call will be received by me in Indonesia.
I can call them and they will see me as local number.
So no long distance call at all
Why I choose IPPI because:
-I can have free inum
-it can be as gateway from SIP to Skype or GTalk and vice versa
