ISDN Telephony is holding your business back

Is your business still using ISDN?

In similarity to PSTN, (Analogue Lines), that are usually used at home for your phone & broadband line, ISDN, (Integrated Services Digital Network), merges several pairs of copper cables, permitting businesses to operate with several telephone calls at once. Following the pattern with all legacy forms of communication, ISDN is pricey and constricting; often seeing businesses spend several hundreds of pounds per quarter for telephone lines & calls alone.

ISDN is the still the leader of voice communications for most businesses, but the end-of-life is already in the distance for this 30 plus year old equipment. BT have broadcasted their intentions to ‘switch off’ all these services by 2025, and therefore drive forward the implementation of VoIP (Voice-over-IP) telephony by trades up and down the country.


Now is most definitely the time to change.

There has certainly not been a better time to evaluate your communications by choosing to cut your use of ISDN whenever your contract permits. You can benefit from the instantaneous cost savings, while increasing your flexibility by moving to VoIP technology.

Using VoIP shouldn’t be a painful & costly experience – there are multiple services and options available these days, with such a competitive marketplace ensuring costs are kept to a bare minimum. Switching from older forms of telephony doesn’t mean you have to leave your numbers behind; you can promptly & simply port these crossways onto VoIP, enabling you to carry on making & receiving calls as you always have done.


What happens to my internet connection?

Switching from ISDN to VoIP means that your calls will no longer be operating scared over those sets of copper cables, but instead across your broadband connection. Reasonably, this means you’ll require a relatively fast & steady internet connection to handle your volume of voice traffic, in addition to the data usage for browsing websites, sending/receiving emails and using cloud tools.

In some areas this isn’t an instant possibility – if your business suffers from slow ADSL speeds and has yet to advance to a fibre connection of some form, you may be apprehensive about the prospect of doing away with the solidity of ISDN.

However! In many cases we’ve seen the savings made from switching from ISDN to VOIP aid in the justification and funding of a dedicated fibre, (known as a Leased Line), connection. By modernizing to a Leased Line, you’ll benefit from a superfast fibre connection directly from your premises to the BT Exchange and attain a much faster connection, which is stable and supported by the network operator on a contractual service level agreement.

As Leased Lines are run on a dispersed basis to each premises, you are not restricted to the limitations of the current Openreach fibre rollout plans – which sees fibre run only from the Exchange to the local cabinets, (with copper still being used between your building & the cabinet as before). Leased Lines, among several other connectivity options, are open to businesses wherever you may be positioned.

With the extra speed & data capacity brought with the installation of a Leased Line, any pain of switching to VoIP is eliminated. Your Leased Line would be more than suitable to carry your voice traffic over VoIP, meanwhile supplying your team with a much faster & reliable connection to the internet than ever before.
