Still using ISDN lines at work? Why now is the time to upgrade your systems

SIP trunks

To be successful in business, you need a telecommunications solution that is going to help you achieve your goals and improve your productivity. Telecommunication enables companies to communicate effectively, deliver the best possible customer service, and collaborate easily between colleagues.

Over the last few years, there’s been a noticeable drop in companies choosing ISDN (the Integrated Services Digital Network), perhaps owing to BT’s announcement that the service will stop being ordered in 2020, and will be completely deactivated by 2025.Many companies are opting to switch to ISDN’s replacement, SIP trunks, to avoid having their phone lines cut when ISDN terminates.

Let’s explore what ISDN and SIP trunks are, and why now is the time to upgrade your telecommunication systems:

What is ISDN?

Introduced by BT in 1986, ISDN is a circuit-switched telephone network system which allows voice and data services to be delivered simultaneously over digital lines. ISDN was designed to migrate outdated landline technology to digital, which was great news for businesses. At the time, companies were excited about ISDN’s potential to support both an analogue phone line and a video-conferencing system, as well as provide the fastest internet available. However, the infrastructure that underpins ISDN has been significantly changed and upgraded since 1986, so BT are now unwilling to invest any further into it. This has been a decision driven by cost, profit, and technological change.

What is SIP trunking?

SIP trunking is the modern alternative to ISDN and is set to majorly overtake it in terms of usage. SIP trunking is a standards-based replacement, connecting your PBX to the PSTN via ethernet, broadband, or private circuit. It works in a similar way to ISDN by combining voice and data traffic. However, instead of utilising traditional phone lines, SIP trunking transmits data over the internet. The service can support connections both large and small, depending on the size of your company and your business need.

Why should I switch my system?

Simply put, SIP trunks are more flexible and lower cost for inbound and outbound voice calls. Call costs are lower, meaning you can approve your efficiency as well as increase your profits. SIP trunking is also quicker to install and is incredibly robust and reliable in terms of its provision to business.

As SIP trunking is based in the cloud, it is easy for features to be installed, upgraded, and adapted according to your company needs.

SIP trunking is also ideal if you are moving, scaling up, or scaling down your company and you’re looking to keep your existing numbers. The advanced technology means that you can add or take away lines with ease.

With SIP trunks, emergencies are handed easily; they provide built-in business continuity. In the event of disaster, business calls can be quickly rerouted to an alternative location.
