That’s the response we often get when talking to businesses still reliant on ISDN2e and ISDN30. And, to be honest, who can blame you? ISDN networks are ultra-reliable and deliver excellent voice quality.

Unfortunately, with BT Openreach due to switch off ISDN lines in 2025, they’re also running on borrowed time. And there are other downfalls:

– Limited flexibility.
– Expensive real estate, taking up far more space than IP communications.
– Engineering costs for maintaining equipment are huge and increasing as demand declines.

So, what should your approach to ISDN be? What are the alternatives? And should you be making a change now?

Look to the future with SIP trunks…

Many businesses have already made the switch to SIP (Session Initiation Protocol) trunks. But what are they?

Simply put, they’re telephone lines on your broadband which leverage network data connectivity instead of dedicated fixed line technology. In order for them to be effective, you need decent internet connectivity as well as a secure and reliable network. However, with that in place, they offer a number of benefits:

They’re typically a cheaper option – though you need to factor in the cost of internet connectivity.
Call charges are lower – in fact calls placed to any 01, 02 and 03 number – and mobiles on a 3-year term – are free, as it’s just data travelling over the internet.
You can keep your telephone numbers – for example if you’re moving or merging offices.
They deliver greater flexibility on cloud services – call centre applications, call queuing and call recording are all straightforward.

…or supercharge your business with Anywhere

If you’re contemplating a switch from your PBX telephone system now, it’s likely that you’re going through a period of change. Perhaps you’re expanding, scaling back or moving offices. Or perhaps you’re looking for a feature that ISDN doesn’t deliver.
