Voice over Internet Protocol (VoIP) is a technology that allows voice calls to be made over the internet instead of traditional analog systems. Some key features of VoIP include:
-
Broadband Connection: A broadband internet connection is required to use VoIP. This can be through a cable modem, DSL, or a local area network.
-
Digital Signal: VoIP services convert your voice into a digital signal that travels over the internet. If you are calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination.
-
Equipment: A computer, adapter, or specialized phone is required to use VoIP. Some VoIP services only work over your computer or a special VoIP phone, while other services allow you to use a traditional phone connected to a VoIP adapter.
-
Protocols: VoIP has been implemented with proprietary protocols and protocols based on open standards in applications such as VoIP phones, mobile applications, and web-based communications. Some of the protocols used include Session Initiation Protocol (SIP), Transmission Control Protocol (TCP), and Real-Time Transport Protocol (RTP) .
-
Security: VoIP protocols include security measures such as implementing access control, verifying the identity of other participants, and encrypting data to protect the privacy and integrity of the media contents and/or the control messages.
VoIP has several advantages over traditional phone systems, including lower costs, greater flexibility, and more features. However, it also has some disadvantages, such as the need for a reliable internet connection and potential issues with call quality.
