How to make the PSTN/ISDN switch-off work for you

Posted 07 Mar, 2019

Big telephone networks around the world are rapidly phasing out traditional analogue and ISDN lines in favour of delivering voice calls over the Internet (VoIP). When BT switch off their old PSTN telephone network in 2025, all customers will be migrated to SIP (Session Internet Protocol) Trunks, the tech alternative to telephone lines.

Many telecoms providers, including BT will no longer offer ISDN products from next year. Indeed it is impossible to get new ISDN services in some telephone exchanges already, so it’s wise to start planning a transition to SIP Trunks now by understanding the opportunities that SIP technology brings.

If it’s not broken!

If your business calls are handled by an onsite phone system, a physical box on the wall, chances are that you’ll probably be connected to the telephone network using ISDN lines that deliver voice to your premises.

It’s something that you rarely think about as long as your system works reliably. When the monthly telephone bill drops you might ponder on the alternatives but then the moment passes, and you get busy again!

If you are planning to expand your business, move to new premises, rationalise office space or are allowing workers to use their own devices or to work from home then a transition away from ISDN to SIP Trunks will bring real value and efficiency into your voice solution. It may even be possible to keep that box on the wall if your current office system is SIP compatible.

Expanding, Moving or Rationalising?

SIP lines or ‘Trunks’ as they are known enable you to easily scale up or reduce the number of channels to the exact number that are required, for example, in response to spikes in business. With ISDN you often had to choose a set number of lines, wasting money on capacity that you might never use.

With SIP Trunks, you’ll no longer be bound to fixed telephone numbers that are location dependent making it easy to move offices without having to incur the costs of call forwarding, new stationery or informing your customers. There will be little or no waiting time for additional lines or upgrades with SIP making on-site engineering a thing of the past.

Why the modern workplace loves VoIP?

Workers have become increasingly mobile and expect to be able to connect seamlessly at home, in the office and at times whilst travelling. Unified Communications (UC) is the integration of telephony with PC, smartphone or tablet to offer internal messaging, web, video and audio conferencing, presence of colleagues and much more. Using only the smallest number of devices, for example just a wireless headset and laptop, even the smallest of enterprises can look bigger by building a unified communications network with video, voice and data all routed over one IP connection.

Add the key benefits of line rental savings of up to70%, and further saving on calls leading to streamlined billing, resilience in case of disaster and 99.95% reliability and it’s easy to see why millions of UK business have already chosen Voice over IP telephony to future proof their businesses.
