Understanding the Basics and Benefits of SIP Trunks

It is not uncommon for users – corporations and enterprises to be precise – to switch to an IP-based telephony service. The technology is certainly more mature and there are solutions that will take the old ISDN lines to a whole new level. Session Initiation Protocol (SIP) trunks and channels are among those technologies, offering more telephone and data volume at a lower operational cost.

Of course, SIP trunks bridge the gap between your PBX system with the internet. How does SIP trunking work? And what are the benefits offered by this system? We are going to answer these questions in this article.

Getting to Know SIP Trunking

As mentioned before, Session Initiation Protocol or SIP is one of the ways to create end connections for data and voice transfers over the internet. Trunking itself comes from an old term that refers to phone lines bundled together; SIP trunks serve a similar purpose and allows multiple users to share the same internet connection to route data and voice.

Business phone networks that used to rely on ISDN lines are now using SIP trunks. The system itself is widely compatible with existing PBX systems, which means you don’t have to make big changes to transition from ISDN to SIP. The only real change that you need to make is adapting the on-premise PBX system to work with an IP-based central terminal.

Of course, SIP also opens up the possibilities of combining PBX systems with other IP-based solutions. Creating a hybrid PBX system of both on-premise devices and cloud endpoints is certainly possible. The same is true for adding suitable hardware that further reduces the cost of using SIP PBX in the long run.

Why Use SIP-Based Telecoms

There are multiple solutions for routine business data and voice, so why should your business go with SIP? Other solutions such as Over-the-Top or OTT are just as appealing, but there are some key advantages that make SIP the more appealing choice in certain situations.

For starters, SIP puts more emphasis on investing in the right hardware. The initial investment then allows for the entire system to run in a very cost-efficient manner. Rather than paying high monthly fees, you will end up with a lower telecommunications cost.

The system itself is also maintenance-free. More importantly, it does not require complex administration. Once it is set up, maintaining a SIP-based system is not only affordable but also very easy.

Of course, SIP also covers the disadvantages of OTT, such as the need to drop your existing carriers or having to shop for a better price. With SIP, you can choose to work with a single reliable provider and have your telecommunications system available at all times.

A Developing Technology

The combination of the advantages we discussed previously makes SIP very attractive as a solution for enterprises. The technology behind SIP trunks and channels are also being developed rapidly due to the higher demand, which means you can expect new features and expansions to be added in the near future.

Is going with SIP the way to go for your company? The answer to this question depends highly on your specific telecommunications needs. However, SIP offers the right balance between flexibility and cost-effectiveness, making it an option that you must consider when you are looking for an alternative to your ISDN system.
