VoIP (Voice over Internet Protocol) allows voice calls to travel over the internet instead of traditional phone lines.
- SIP – Starts, manages, and ends the call
- RTP – Carries the actual voice packets
- RTCP – Monitors call quality (delay, loss, jitter)
- UDP – Delivers voice data fast with low latency
Together, these protocols make VoIP calls fast, reliable, and cost-effective for businesses and individuals.
