What is VoIP? (Voice Over Internet Protocol)
Traditionally, legacy phone systems carry voice signals using analog phone lines so it requires the setup of circuit wiring to make and receive calls. Under this circumstance, a piece of specialized hardware equipment called Private Branch Exchange (PBX) is used to connect internal phone extensions to the public telephone network.

Rather than sending data packets over a traditional circuit-switched network, VoIP, the abbreviation for Voice over Internet Protocol, sometimes also referred to as IP telephony, is a technology that converts voice into digital signals that can be transmitted over internet digital data packets via your local area network/WAN/other infrastructure to enable phone calls. VoIP uses RTP (real-time protocol) to ensure that these packets get delivered timely. You can use either an ethernet cable or a high-speed WiFi connection for VoIP.

How Does VoIP Work?

As mentioned above, VoIP basically works by converting analog telephone signals into digital signals to facilitate telephony over the Internet. Now let’s dive a little deeper into detail into the process.

SIP Protocol and SIP Trunking
Voice over IP works by using protocol technologies and SIP is one protocol that enables VoIP. Session Initiation Protocol (SIP) is a communication protocol for VoIP calls and other text and multimedia sessions, such as instant messaging and video. SIP trunking, based on the SIP protocol, is basically a service established virtually over your internet connections and provided by Internet Telephony Service Providers (ITSP), eliminating the physical connection to a phone company.

Terms and Conditions
General terms
VoIP technology uses the Internet to make phone calls. You need an existing internet connection, such as Fibre or LTE to make VoIP calls.
The Pure VoIP service is entirely dependent on the quality of the Internet connection you are using when making or receiving a phone call.
We only recommend connections that do not generally suffer from congestion or high latency, such as Fibre or Fixed LTE.
Other connectivity types, such as DSL, 3G, Wi-Fi or Mobile Data will work. However, we do NOT recommend relying on these connectivity types as they are prone to congestion and high latency which result in poor call quality unless you have a dedicated internet service for your VoIP system.
