Wouldn't that be TCP only?  RTP is UDP and you don't want to use TCP for
phone calls.
RTP is real-time and TCP would not be good in that case but the call setup and management are not so real-time and can use TCP.

You would likely want to protect your call meta-data and not just the voice component.
