SIP Trunking (Session Initiation Protocol) is a hot topic in unified communication and among businesses that strive to keep up with technology advances. Let’s talk numbers. In North America, 45% of businesses are using SIP Trunking with an increase of 67% predicted by the year’s end. There is no doubt this is an important topic to explore thoroughly. This blog post will give you valuable insights on what SIP Trunking is, how it works, its benefits, etc.


SIP Trunking is a method by which business phone systems can operate using an Internet connection instead of a traditional phone line. It facilitates the connection of a private branch exchange (PBX) to the Internet with the use of voice over IP. To put it another way, SIP trunk connects your internal phone system with ITSP (Internet Telephony service provider). You will be able to use VoIP telephone outside of your company’s firewall without setting up IP-PSTN gateway. SIP Trunking is provided by SIP providers, which are similar to traditional phone companies, except the fact SIP providers give access to phone lines over the Internet, not analog lines.


SIP Trunking works hand-in-hand with VoIP phone system that understands the data provided by the trunk.  Traditional phone systems carrying analog lines require a SIP gateway to connect. However, the businesses will not reap all the benefits of SIP Trunking. SIP gateways transform the data in a way traditional PSTN understands. SIP Trunking enables getting real-time data information, such as video, images, Caller ID, call waiting ID, etc. However, you can’t take advantage of this benefit if connecting via the analog phone system. The best bet for businesses is using a router to prioritize the information presented by SIP. Think of it this way. You are receiving email while having a conference call with your employees abroad. SIP Trunking prioritizes the received data and allocates it so your call stays consistent.


Sip trunk is used to carry a set of real-time communication services. Using SIP Trunking you will be able to: - Initiate and receive local calls - Initiate and receive long-distance calls - Access directory assistance - Conduct multimedia conferences (video, images, etc.) - Get user presence information (Caller ID, call waiting ID) - Make E911 emergency calling - Use fixed and mobile telephone sets - Employ e-mail and texting - Browse the Internet


We are always being asked whether large businesses take advantage of SIP Trunking more than small ones. The main point is SIP Trunking is beneficial for all businesses regardless of their size and industry. SIP Trunking enables large businesses to easily maintain their local presence in different corners of the world. Small businesses, on the other hand, take huge advantages by looking more professional and larger than they actually are. But, one benefit is general to all of the businesses. It’s cost-effectiveness; the biggest benefit of SIP Trunking. This is true especially for SIP Trunking and VoIP gateway solutions designed for your business success.  Costs less - Saves money on your business phone, it’s less expensive to set up, maintain, and upgrade. Besides ITSP like VoIP providers deliver telephony service at a low price in comparison to traditional phone service providers. So you will make substantial savings on your monthly phone bill.

It’s also easier to configure, which makes the scaling process painless. This level of scalability makes SIP Trunking future-proof.

Flexible - It's a fantastic choice for any business that has an international location. Why? Because you can easily take your phone number with you while moving offices and traveling. Network outages are much less impactful because incoming calls can easily be routed to other locations.
