# BT 2025 Switch off likely to affect 2 million UK Businesses

*Come 2025, BT will conduct major changes to its services, permanently switching off important communications networks like PSTN and ISDN. It is estimated that the switch off is likely to impact nearly 2 million UK businesses. Find out what will happen and how will it impact your business.*

**What is happening with the BT 2025 switch off?**

National telecoms provider BT has announced they will shut off their ISDN and PSTN services.

The move ends the use of analogue phone lines and moves communications technology into an entirely new online space.

BT will no longer offer businesses the ability to acquire ISDN and PSTN after 2020, with the total switch off occurring in 2025. After the switch off, there will be no maintenance or recovery of phone lines, and any data sent will no longer be carried through ISDN and PSTN.

**How does it Impact business communication?**

Industry experts say that this is a part of cost-saving efforts by BT. It is estimated that over 2 million UK businesses will be affected by the switch off. This will primarily include the smaller companies.

Businesses will need to look for alternative methods of data transmission to maintain communication coverage. VoIP is emerging as the sole runner for replacing the traditional phone systems.

**Where do you go from here?**

BT is pushing customers towards its VoIP solutions, enabling them to keep their old technology that currently operates over ISDN and PSTN.

Savincom would suggest that instead of just updating transmission methods to VoIP, businesses should consider improving their entire system.

**Who will be affected?**

The BT 2025 switch-off will impact all businesses currently operating ISDN or PSTN.

The switch-off will affect a large volume of small businesses, as these organisations are less reliant on more advanced and diverse communication platforms than larger companies, meaning they haven’t needed to upgrade their systems.

42% of SMEs still use analogue lines to transmit data. That’s around 2.4 million businesses. And, while many bigger companies and national brands have already updated their data transmission systems, not all have made the switch. Roughly 33% of larger firms still operate on ISDN or PSTN. Essentially, there are still a lot of British companies reliant on fixed landlines for communication.

**How will your business be affected?**

To find out if your business will be impacted by this switch off and to what extent, you will have to analyse the number of traditional phone lines are you currently using.

**What are the alternatives after the BT 2025 switch off?**

When it comes to adapting business technology following the BT 2025, the big push is towards VoIP.

VoIP — or Voice Over Internet Protocol — is a method of data transmission that allows for voice messages and images to be sent over the internet using your current hardware. But how? Didn’t we just say you can’t plug your fax machine into your computer and expect it to work?

Traditionally, information from the telephones travelled down a hard-line to your copper-wire landline. Data then transmitted — via ISDN or PSTN — through this wire. With the wire no longer operational following the BT 2025 switch off, the data must go elsewhere. How VoIP works for your phones is simple. Using an adaptor device, you can turn your landline-reliant fax machines and phones into hardware with internet connectivity.

In essence, VoIP means you can use your current hard-line devices to send information to other hard-line devices, but through the internet. The result is minimal change to your systems while maintaining communication coverage, even after the BT 2025 switch off.

**Better business communications solution for businesses**

With the BT 2025 switch off looming, businesses will be considering making changes to their data transmission systems to avoid potential disruption. While VoIP may appear to be the easiest solution, it does not offer you the best opportunities. During this period of transition from legacy systems to newer services, why not take advantage of the ultimate in fax sending solutions, instead of continuing to rely on hardware just as dated as the technology removed in the first place? 

Looking to make the big switch to VoIP? Get in touch with Savincom today. We work with major VoIP providers like One net by Vodafone, Gamma by Horizon, Call switch by Telco switch and 8x8. We will be able to provide you with quality service and the best rates. For order and enquiries please visit us on [www.savincom.co.uk](http://www.savincom.co.uk)

I would like to thank savincom for the hard work that they have done, they have managed to meet all our requirements and have delivered it in a timely fashion. They have reduced our monthly outgoings for our mobiles by a 1/5 of which we are very happy about.

 Maintenance Manager, Luxury Hotel Group

Since moving to Savincom, we have received excellent and responsive customer service, the small number of issues we have experienced have been resolved in an efficient and expert manner. We have significantly reduced our running costs, with the proactive account management, currently running a reduction of c.40% on costs, the cost reduction has been most prevalent around roaming and international calling. The transfer from Vodafone Direct to Savincom Vodafone was smooth and seamless, with onsite support offered during the days of the transfer. If I was to score them out of 10, it would be 10 as the have excelled as a service partner.

 Office Manager, Leading Global Commodity Merchant

We have worked with Savin Communications for four years now and we are delighted with the work carried out so far.  We have 300+ connections, so service needs to be of the highest quality, which is what we get with Savin Communications. We have a rapid staff turnover and Savin assist us when utilising connections. We used to be on a plan where we were constantly going over minutes and data allowances. Savin Communications has helped us source a much better quality plan and they understand the high standards that our organisation have and are most efficient in delivering well within time limits…. The account manager is always easy to contact and help is really appreciated, meetings with him are regular. The assistance and support we receive is always   
 responsive, proactive and excellent at all times. The advice given is easy to understand along with their online portal which is easy to use too, communicated in a friendly accessible manner. I would highly recommend Savin Communications.

 ICT Manager, National Charity

Having paid overly expensive mobile phone bills for several years, we switched to Savincom who assured us of substantial savings, especially for our mobile phone usage abroad. They were not wrong! Our bills have practically halved since the switch and furthermore Savincom provide a great support service, with any queries or problems being acknowledged and dealt with swiftly and professionally.

 Finance Manager, Global Shipping Company

I can confirm that we switched over our account from a direct one held with one of the Networks, to one under Savincom’s control and have been more than happy with the service thus far. As a Canadian Investment Bank with frequent overseas travellers, I found doing business direct with the Network over the past few years and my numerous dedicated account managers very frustrating indeed. Wrong price plans, outdated tariffs, changes of Account Managers, limited cover on the weekend support desk, and bolt -on’s not being applied to our overseas travellers etc. We are seeing benefits in not having to deal with the Network directly. I would be happy to recommend them in terms of the mobile contract that they proposed and especially their customer service.

 Operations Manager, Investment Bank

Since using Savincom our bills have noticeably decreased and every possible bundle is being added and removed when necessary. The service levels are a world away from what we experienced previously; I get a response back from their support team in at least 5 minutes, and everyone is extremely helpful. The account management is makes a big difference as well. Everything is straightforward and I can request information on our account and be sent a detailed report. I would highly recommend Savincom.

 Office Manager, Investment Company

I have used Savin for the last 4 years and their customer service, support, timescale to response and resolve any queries etc. has been first class! I am the IT Manager for a large construction based Group and as you can appreciate we have a large number of guys based on construction sites who break their phone frequently (and lose them!) so I require a swift service to replace phones and sims, bar phone lines and order new lines (either phone or 4G dongles) ASAP, all of which Savin deliver! So I would recommend Savin without hesitating!

 IT Manager, Construction Group

The highlight for me is being able to shoot an email to Savincom support and almost   
 immediately getting an engaging response, they want to solve my problems rather   
 than assign blame to someone. Overall we are very pleased to be working with a great team.

 IT Manager, Private Equity

Savincom are my righthand. I just phone and everything gets dealt with – no more long maddening calls to mobile providers. Thank you Savincom. You guys rock!

 Andrea Sequeira

Not only have our monthly bills been cut by more than half, savincom saved hours of my time spent on the phone to network direct customer support lines.

 Sujin Bailey

Having had our mobile phone contracts managed by savincom has saved the company considerable time and administrative effort.
