In this case, the SIP works as an extension of your current phone system. Instead of going through a traditional phone line, a SIP trunk uses your Internet connection to transmit voice and data. Here is how SIP trunking can be used: Scenario 1 A recent report from Software Advice showed that 69% of organizations use SIP trunking in some form. SIP trunking is everywhere, and more common than you might think. Instead of ripping out and replacing the entire phone system, which can be expensive, they may choose to add a SIP trunk, which allows them scale and save money without having to write off their previous investment. As organizations grow, they often come across this capacity barrier. A PBX has a maximum number of calls that can be going on simultaneously on the same network. One of the biggest flaws of this type of phone system is capacity. The voice data travels through either a copper analog line or an ISDN (Integrated Service Digital Network) line. With that infrastructure, users dial a phone number, and it goes through a PBX (Private Branch Exchange), which routes the call to your number you dialed. This model is vastly different from the traditional phone system. The way that billing works is that companies can pay per minute or they can pay based on how many concurrent lines they want to be able to access at any one time. Now, companies can buy SIP trunks to accommodate the entire organization. How SIP Trunking Worksīefore the days of SIP, companies had to purchase lines to support the number of concurrent users expected to be on the phone at the same time. Therefore, if you have a VoIP phone that needs to communicate with a landline, you’ll need SIP to make it happen. Unlike a VoIP phone, a SIP phone can communicate with other protocols. For this reason, SIP phones are seen as more traditional phones, while a VoIP phone can encompass a variety of devices, including desktop computers and tablets. However, a SIP phone only needs a modem to function, and it operates independently of a computer. A VoIP phone or handset must be connected to a computer to work. It’s also worth clarifying what the difference is between a SIP phone and a VoIP phone. This negates the requirement for dedicated voice circuits and can lead to significant cost savings for an organization. In the past, companies used to have to purchase dedicated circuits for voice calls, but now companies can use their existing Internet connection and purchase SIP services directly. So, what does SIP trunking actually mean? In simple terms, SIP trunking is the ability to make and receive voice calls over your existing data or Internet connection. A trunk is a line that carries the signals. SIP trunks are used in conjunction with IP-PBX systems to replace traditional PRI and analog circuits. SIP trunking uses a data connection that combines session initiation protocol (SIP) and real-time transport protocol (RTP). Now that you know what SIP is let’s define SIP trunking. To sum up the difference, VoIP encompasses a wide array of technologies to function, and SIP is one of them. So, you can think of SIP as the protocol that makes VoIP possible. It relates to making and receiving calls using an Internet connection. In reality, VoIP is a broad term that refers to any Internet-based phone service. Though you’ll often hear VoIP (Voice over Internet Protocol) and SIP used interchangeably, this is an inaccurate oversimplification. SIP is the protocol that enables VoIP, the technology that allows voice calls to be transmitted over the Internet. The secret is SIP, aka Session Initiation Protocol. Have you ever wondered how companies like Skype and Facebook are able to provide users the capability to communicate with people all over the world for free?
