What is SIP calling?

SIP calling is also known as Session Initiation Protocol calling. Session Initiation Protocol is a signaling protocol used for initiating, maintaining and terminating communication sessions over VoIP and other Internet and cloud-based communication platforms. SIP calling is often interchanged with VoIP calling, however, that isn’t exactly correct. VoIP (Voice over Internet Protocol) is a broader term that refers to a group of technologies used for sending and receiving phone calls made over the internet rather than traditional phone lines. While SIP is one individual technology that supports VoIP. In addition to voice calls, SIP protocol is used to transmit various data, including video chats and video calls, video conferencing, instant messaging and other multimedia communications.

Apart from initiating telephone calls, a SIP phone system is capable of performing other VoIP functions, such as identifying user location, determining their availability to respond and whether the recipient’s device is compatible with the initiated call type, transferring and terminating calls, etc.

How does SIP calling work?

A traditional phone system consists of three core parts:

Private Branch Exchange (PBX), an on-premises telephone system that manages calls.
Primary Rate Interface (PRI) lines that connect calls to the PSTN.
Public Switched Telephone Network (PSTN) that routes calls to their destination.

SIP calling basically allows omitting PRI lines as it uses a SIP trunk (which is a virtual connection) that directly connects PBX with PSTN over the Internet. SIP calling also removes the need for multiple phone lines which allows for easier and cheaper scalability as compared to using traditional business phone lines.

Since each SIP trunk can hold an unlimited number of channels (a channel is equivalent to one incoming or outgoing call), a business would require a single SIP trunk regardless of the number of concurrent calls. Instead of purchasing additional phone lines that usually come in clusters of 23 (which is typically more than actually used), with SIP calling you can buy one channel at a time only when it’s needed. Besides, SIP calling provides significant cost-savings in business communications as local, long-distance and international calls can be made by simply using the internet connection.
