SIP is pretty easy. Normally it uses 5060 port. But prioritizing this port traffic won't enhance the overall voice quality. RTP ports are decided dynamically during SIP handshake. To filter RTP protocol from packet pattern will delay the traffic. So using port number is easier way, BUT, you need to find out these ports from the SIP handshake messages. How to prioritize depends on your setup's capabilities.
