Hi,

Both RTP and SIP based on UDP (sometimes TCP) protocols. So we are
already using TCP/UDP to carry audio. Why we need a high-level protocol?
Because:

1. we need to format data (RTP)
2. we need to control data. (SIP)

Why we mostly prefer UDP and not TCP? Because of efficienty. Low
protocol overhead, low bandwidth.
