Voice over Internet Protocol (VoIP) is a method of transmitting voice calls over the internet. It has grown in popularity for personal and commercial purposes and is a direct alternative to a public switched telephone network (PSTN). At its core, VoIP offers a simple solution to telephony using an established online network. So, how does VoIP work?
How do VoIP phone systems work?
VoIP sends and receives voice calls over an internet connection. This is different to traditional telephony, which uses landlines or a mobile network to make voice calls. VoIP calls are converted from an analogue voice signal into a digital one, compressed, and then sent through the internet. VoIP calls work seamlessly with other telephone networks including traditional PSTN or ISDN landlines and mobile networks.
As video calls, instant messaging and web conferencing are all available, VoIP greatly benefits from steady, high-speed, broadband.
VoIP Hardware Options
VoIP is usually set up using a normal desk telephone handset and a session initiation protocol (SIP) server. The result of this is that businesses that have already invested in analogue phone equipment can use their existing hardware with the VoIP system.
Using a desk telephone for VoIP can be beneficial to users as it offers the same range of functionality that existing landline phones provide. However, one of the advantages of VoIP is users can make and receive calls through a headset connected to their computer or even through an app on their existing mobile phone. The range of different hardware choices that VoIP supports is one of the key benefits for organisations.
As VoIP uses the internet to transfer voice call information, some VoIP software (such as 3CX) allows call information to be viewed and managed by an online dashboard. This allows for contact creation and editing, call forwarding, voicemail, and a range of other features.
Most people have a reasonable internet connection at home or at work. This makes VoIP a simple integration into current setups. Better yet, organisations switching to VoIP can save as much as 40% on their existing solution.
