The comm package can help you dial a modem using Java but it will not help you with VOIP. VOIP substutes a computer network for the telephone network. Since they're two different systems, you can't touch a normal phone with VOIP without something somewhere making the crossover. First thing to do is understand what VOIP is. There's a good intro article at How Stuff Works.
I'm a new bie to this ip-telephony. So let me start this first. Is Java's Multimedia Framework is enough to do a Voice chat program, some thing like yahoo voice chat. It's like PC-PC so no PC-Telephone.
Do i need any external pheripherals for this ? [ June 27, 2005: Message edited by: Srinivasa Raghavan ]
