Hi you guys, i want to start a new business. As you can see at lowercaller.com you can choose between the cheapest voip companies. Now my question is: Is there a way to start my own telephone office where callers pay for every minute a standard rate? How can i accomplish this?How many voip gateways do i need if i want to connect 10 computers.Is there any software for lowercaller.com so that it chooses automatically the cheapest voip company?
