[LARTC] Filtering RTP/SIP protocol (Voip)?

[Salim S I]

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.
