Does JXTA supports voice chat?

I'm developing a LAN messenger in java. I'm following P2P approach using JXTA for sending message. Now I want to add extra functionality of audio chat. My main problem is that does JXTA supports sending of voice data?

I don't think there is an out-of-the-box solution for this in JXTA. But you can use a BidirectionalPipe (which should be using UDP) for the communication. Check this book.
