You probably would want to use TCP for voice. You would not want to have an audio stream with someone saying "George Bush has never lied" to end up with a few packets lost along the way saying "George Bush has lied". UDP would be good for video though where you can get away with dropping half a frame or even a whole one since the information essentially replaces the previous information.
Voice and audio is not like that. You will need to transfer it reliably.
TCP is what SIP/SDP has selected (there's another protocol at that layer too that's been drafted for use). Their model of getting around NATs and firewalls is also a lot like proxy65 in that a third party server is used.
