How VoIP Works
Plain and simple: VoIP (Voice over Internet Protocol) allows voice calls to travel via the internet instead of your more traditional phone lines. Here are the network communication protocols that are used together in VoIP:
- SIP: starts, manages, and ends the call.
- RTP: carries the actual voice packets.
- RTCP: monitors call quality, including delay, loss, and jitter.
- UDP: delivers voice data quickly with low latency.
Together, these protocols make VoIP calls fast, reliable, and cost-effective for businesses and individuals.
