What is SIP and Why Your Business Needs It

SIP trunking is a telephony protocol that makes calls over the internet by controlling and establishing the transfer of data. 

Instead of the traditional standard Public Switched Telephone Network (PSTN), SIP has revolutionized the way companies handle voice calls, video calls, and text messages, among others, which is why it’s an essential step if you are looking to invest in unified communications. But since it’s a complex system, we broke down what SIP is and how it can benefit your business. So, read on.

          1. Let’s Start Here: What is SIP Trunking?

To put it merely, Session Initiation Protocol (SIP) is a technology standard that is used for performing multimedia communication sessions over the internet. SIP trunks can also be described as virtual phone lines that allow you to make and receive calls over the internet to anyone in the world with a phone number. According to verified reviews submitted on, many businesses have attributed that SIP trunking helped them save up to 60% of their communication costs and helped to increase flexibility in their business operations. A “trunk” in this case, is a line or link that carries a signal and helps to connect nodes in a communication channel between two locations. SIP trunks have the capability of hosting an unlimited number of channels with the bandwidth your business wants. 

          2. The Benefits: Lower Operational Costs

There are many ways through which SIP trunking contributes to cutting down expenses. Most notably, this is through the elimination of expensive PRI lines and associated long distance calls. Although this sounds like the bottom line, you will realize that the advantages of SIP trunking are immense in comparison to traditional methods like analog lines and ISDN. SIP trunking requires minimum onsite infrastructure beyond efficient connectivity since its cloud-based. This helps to save online rentals and other maintenance expenses.

          3. Offers Flexibility

The design of Session Initiation Protocol (SIP) is highly flexible since it allows your business to have as many lines as it can. What this means is that small business can pay lower rates for just a few lines. However, this is not the same case with larger organizations. Large organizations only need to pay a little more for their rates to get as many lines as they like, especially if your company is a call center or a large sales department.

          4. Easy to Manage

You don’t need to have the technical expertise skills of a telecommunications expert to install and use SIP trunking. Many of the solutions available in the market provide a control panel that is easy to use, which has simple instructions for installing and configuring your existing PBX.
