Hi, I am attempting to setup a VoIP based phone-to-phone service between two countries. All customers in Country A, will be able to dial a certain number(s) (in their local calling area) and those customers who have valid PINs or call from pre-authorized phone numbers will be able to make calls to Country B. All the calls will be transferred over the internet, between the two countries and PSTN shall take over in Country B. I would like to start off with about 20 simultaneous connections. Can you folks please provide me with pointers for a low cost setup. Answers to the following would be preferred: 1) Bandwidth required 2) Equipment required (in both countries) 3) Any off-the-shelf packages 4) Setup information 5) Can this be achieved with Asterisk? Other PBXs? Kerry
