What is SIP Calling?

SIP (Session Initiation Protocol) calling is the process of transmitting voice calls over a SIP trunk or a SIP channel, and it works with VoIP systems. SIP calling actually uses VoIP to move your analog call traffic over an internet connection.

How does a SIP call work?

A traditional phone system consists of three parts:

  • PBX (Private Branch Exchange): your on-premises system that manages your calls
  • PRI (Primary Rate Interface) lines: lines that connect calls to the PSTN
  • PSTN (Public Switched Telephone Network): the network that routes calls to their destination

SIP calling eliminates the need for PRI lines. A SIP trunk, a phone line that uses the SIP protocol, is virtually installed over your internet connection. It then uses this internet connection to connect your PBX to the PSTN, bypassing the PRI lines. SIP can use call management features like auto attendants, call forwarding, voicemail, and much more.

Here are some of the benefits of SIP calling:


You can save up to 80% on your phone bills.


All calls and video conferencing occur over the internet which means you don’t need to purchase more lines if your company grows.

High Quality Calls

SIP ensures reliable, high-quality calls.


Since your system won’t drop calls, productivity can only go up.

User Experience

You can take full control of your entire business phone system with an easy-to-use computer interface.

SIP allows you to work, remotely

SIP service is the answer to outrageously high phone bills, and SIP trunking can eliminate a wired connection, giving you the freedom to work away from the office. It allows you to do all of your business online.
