Voice over Internet Protocol, or VoIP, is a technology that allows phone calls to take place over the internet. IP phones, also known as VoIP phones, come in a number of varieties, depending on an organization’s particular needs.Among a broad spectrum of VoIP office phones, there are both corded and cordless varieties for businesses to choose from depending on whether extra mobility will be useful. There are also VoIP phones that are specifically designed for conference calls, have speakerphone functionality, some that offer video calling, and others that work best in call centers. IP phones have a number of benefits over traditional phones: they are easier to use because they allow you to make and receive calls from any Internet-connected device, and reduce your phone bills because you only have one line to pay for. They also offer greater security than regular residential telephone lines because all calls go through the Internet rather than being routed through third party carriers.
