What is VoIP? VoIP is a method of transmitting voice calls over the internet instead of traditional telephone lines. This technology converts the voice signals into digital packets and transmits them over the internet. It allows for a more cost-effective and efficient way of communication, especially for long-distance or international calls.

VoIP has become increasingly popular in recent years due to its ability to provide additional features such as call forwarding, conference calling, and voicemail at a lower cost than traditional phone systems. Additionally, VoIP can be easily integrated with other communication tools such as instant messaging and email.
