Sure. TLS is nothing but a new incarnation of SSL v3. Have you heard of old wine in new bottle? :-) It is exactly that. As to VoIP I am afraid I don't know since skype uses its own encryption mechanism that is proprietary. Since VoIP mostly uses an underlying NAT traversal and instant messaging kind of library underneath you should take a look at protocols like SILC (Secure Internet Live Conferencing). The only difference between data encryption and voice encryption being that voice is very very delay sensitive and data is very very loss sensitive. So UDP is used for voice and TCP for data. I am not quite clear if SSL is used for VoIP. I doubt. One possibility is DTLS...
