How will the clients exchange the key for the RTP encryption? Will it be
sent in the SDP? If yes, wouldn't I also need encrypted SIP to hide the
RTP key?
Yes the keys will be exchanged within the SDP. So indeed you should crypt the
SDP in signaling either by using TLS or S/MIME. Otherwise someone could read
the keys from the signaling and decrypt the RTP streams.
