Join us as we delve into the 5 key advantages that make SIP trunking a game-changer for businesses this year. From cost efficiency to global connectivity and advanced features, discover how SIP trunking is reshaping the way businesses communicate, setting the stage for a more scalable, flexible, and interconnected future.

What is SIP Trunking?

SIP, or Session Initiation Protocol, is among the various protocols available for Voice over Internet Protocol (VoIP) communications, functioning much like HTTP does for web pages. It serves as the mechanism for transforming voice signals into data, enabling devices used by callers to receive the information.

 Contrary to the term “trunking” which historically referred to a bundle of shared phone lines, modern SIP trunking establishes a virtual link between a Private Branch Exchange (PBX) and the standard phone network (PSTN) via the internet. With the gradual phasing out of traditional methods like ISDN, SIP trunks have emerged as the contemporary industry standard for connecting business phone networks over the internet, especially for those with modern IP PBX systems that support SIP for data transfer.

SIP Trunking Advantages

The importance of a communication advantage in business lies in its ability to enhance productivity and innovation. When teams can communicate seamlessly, share ideas effortlessly, and receive timely feedback, it creates an environment conducive to creativity and problem-solving. This agility is especially crucial in industries where rapid adaptation to market changes is imperative.

Reduced setup costs

Purchasing SIP Trunks is an extremely cost effective way of implementing hybrid VoIP working into your business. However, you have to be careful of the SIP resellers out there! Many telecom companies resell SIP Trunks which they purchase from a larger entity with their own network.

This often leads to higher trunk prices due to them having to add their own margin. For industries such as healthcare, education and call centres these small margins evidently add up due to the amount of SIP Trunks they need. This is why it is beneficial to do your research and find an independent network provider such as Fuse 2, as there will be no extra margin added on top – meaning more cost effective and efficient communications!

Flexible sip trunk upgrades

SIP technology is one of the most flexible communication methods in the market. Whether you want to increase or decrease the amount of SIP Trunks your business has, or even expand your communications into different countries – SIP can do all this effortlessly.

As well as the effortless implementation of changes, these upgrades also come at a fraction of the price that would typically come with upgrading a traditional phone line in such ways. This is a perfect solution for the ever evolving landscape of hybrid working and modernised communications! 

Increase value of your existing infrastructure

By investing in SIP Trunks for your business, you are not only guaranteeing increased call quality and more reliability for your communications, but you are also ensuring that you are investing into your existing infrastructure.

SIP Trunks can greatly increase the value of your infrastructure by modernising the existing elements, therefore ensuring that your systems are fit for the future. SIP Trunks are also compatible with most hardware (desk phones) therefore there is no need to upgrade any existing hardware you may have as these can be seamlessly integrated with each other – therefore saving you money!

Secure phone calls

The security of a SIP Trunk is all dependent on the security of the network in which the SIP Trunks are being distributed from. Each SIP trunking platform provides different levels of protection features and it is essential to research these features before making your final decision.

SIP Trunking requires an internet connection which therefore leaves systems vulnerable to internet attacks. This could include hackers attempting to overload your system by placing costly international calls on your trunks – this is known as a DDoS attack. It is crucial that you find a network provider, like Fuse 2, who is ready for these threats and ensure that they have mitigation strategies in-place to stop this before it escalates.

SIP Trunk advantages you may not know about

Your business communication goes beyond the conventional methods, and one powerful tool that might be flying under your radar is Session Initiation Protocol (SIP) trunks. While many are familiar with SIP trunks for their cost-effective and scalable nature, there are several hidden advantages that often go unnoticed

24/7 Backups

Theoretically, you can’t have backups on a SIP trunk as they are a service of the network. The backup aspect has to be implemented within the network’s integral infrastructure. At Fuse 2, we have  24/7 monitoring on the network which includes always-on failovers and in depth call reporting deep within its core. These allow our technical team to have full visibility on what enters and leaves the network and also allows the team to see unusual occurrences in call traffic and volumes.

We offer automatic failovers which means in the event of a sudden outage all of our SIP trunks, call traffic and other services will be seamlessly transferred over to another of our data centres ensuring no calls are dropped. 

Faster ROI

Traditional phone systems are costly and hard to manage which could result in an increase in investment to ensure they are working as intended. As the traditional infrastructures become more outdated, the solutions and manpower needed to fix any issues can come at a big price. This also means that businesses may have to hire additional staff who manage the integral workings of their phone system.

In short, keeping a traditional phone system can cost more money in management and up-keep than it’s worth! The additional money could be used for many different areas within your business, therefore enhancing the way your business operates! A SIP enabled phone system also comes with many additional features that ensure a better customer experience – which is great for your ROI. 

Global Scalability

SIP Trunks can be provisioned anywhere in the world, as long as you have chosen a globally diverse provider! Global scalability is essential for any businesses operating in the post-COVID world as we have seen a rapid growth in flexible, global working.

If your business is planning to expand globally, whether that be for your staff or your customers, provisioning a traditional phone line to handle all of these calls will be costly and hard to manage. Whereas, with SIP Trunking your business can continue to scale globally with the peace of mind that you will not be met with a heft phone bill at the end of the month! 

Increased Redundancy

At Fuse 2, we have multiple data centres that accommodate for increased redundancy. Security, Reliability and Redundancy where the building blocks for our network and we have intelligent failover mechanisms that will automatically switch to alternate data centres / paths in the event of an outage. This redundancy technology significantly reduces the chance of complete communication outages. Redundancy is one of the most crucial factors to look for when looking for a service provider, as it is essential to know that your communications will remain untouched in the unfortunate event of an outage.

 Fully managed service

A fully managed solution by Fuse 2 is the simplest way to effectively enhance your communications. Telecoms can be confusing at the best of times and if you add cloud communications into the mix, it can be a minefield! That’s why you leave it to the experts! 

Typically, if you choose to host and manage your VoIP communications yourself, you will be met with many different suppliers offering many different services. This therefore results in multiple invoices at the end of the month, which can be hard to keep track of. Whereas, with a fully managed service from Fuse 2 you will receive one invoice at the end of the month with all cost’s included.

You will also receive a dedicated account manager and the support of a highly skilled team of technical engineers at no additional cost. Your system will be configured, set-up and tested by our technical engineers to ensure everything is working as it should be and will be closely monitored throughout your contract to avoid any issues/outages.

What businesses are using SIP Trunking?

Due to the flexibility and scalability of SIP Trunks, there are no limits to what business can use this technology. Companies big and small around the globe have adopted the SIP technology and see many benefits with their internal and external communications.

SIP enables businesses to benefit from a number of features to improve communications, including advanced call forwarding and re-routing services. This is great for businesses such as schools, medical centres and financial companies who have multiple departments and need to allocate and route their calls accordingly. 

How SIP Trunking works

SIP (Session Initiation Protocol) Trunking is a digital way of making and receiving phone calls and other communications over an internet connection. The term trunking refers to the method of consolidating multiple communication channels into one singular connection.

SIP Trunks work as a connection between your business phone system and the Internet Telephony Provider (ITSP). This works by using the SIP Trunk to route communications over data networks via a SIP-compatible PBX (Private Branch Exchange). This process may sound complicated however, this will all be handled and managed by your chosen provider.
