Voice over Internet Protocol (VoIP) is a technology that allows users to make telephone calls using the internet instead of traditional telephone lines. VoIP converts the analog audio signal of a telephone call into a digital signal that can be transmitted over the internet. This allows users to make and receive telephone calls using a computer, smartphone, or another internet-enabled device.
There are several different types of VoIP services available, including:
- Hosted VoIP: This is a service provided by a third-party company where the service provider maintains and manages the VoIP system.
- Cloud-based VoIP: This is a service where the VoIP system is hosted on a remote server and accessed through the internet.
- On-premises VoIP: This is a system where the hardware and software for the VoIP system is maintained and managed by the user.
Some of the advantages of using VoIP include cost savings on long-distance and international calls, the ability to use a single phone number for multiple devices, and access to advanced call-handling features such as voicemail, call forwarding, and caller ID.
However, depending on the quality of the internet connection, VoIP calls may not be as reliable as traditional telephone calls.
