VoIP or Voice over Internet Protocol is a phone service that connects via the internet through an internet modem instead of a traditional landline. Most VoIP services work with cable or DSL modems. To establish the connection, connect an adapter from the VoIP provider to your modem, which translates your voice into data packets sent over the internet. An internet connection is necessary, and most VoIP plans require a touchtone phone.

Cost-effective: VoIP utilises existing internet infrastructure, eliminating the need for separate phone lines. This reduces setup costs. 

Advanced Features: VoIP offers features like Call Forwarding, Caller ID on your TV, voicemail transcription and more.
