VoIP (Voice over Internet Protocol)
Voice communication over internet is called as VoIP (Voice over Internet Protocol) or internet telephony.
- Real time voice communication is performed through telephones, but this is done with the help of internet.
- Phone-to-Phone communication is created using this technology; the internet is used for long distance data and voice transmission.
- VoIP service is cheaper than conventional telephone services.
PSTN:
- PSTN stands for Public Switched Telephone Network is a world collection of interconnected voice-oriented telephone networks.
- It consists of cellular networks, microwave transmission links, undersea telephone cables, fiber optic cables, communication satellites, and telephone lines all interconnected by switching centers, therefore it allowing many of the phones to communicate with each other.
