Segmentation Group, the authority in data analytics and telecoms management, discuss the ever-present need for control and cost reduction, alongside preparations leading up to the ISDN / PSTN Switch-Off

Established in 2005, Segmentation Group is a dynamic, independent, data analytics and telecoms management company, dedicated to translating complex, legacy networks into transparent, future-proof solutions, by bringing all the strands of your equipment, network and costs together to provide insight, analysis and recommendations.

We are the authority in data analytics and telecoms management and our dinosaur to astronaut approach enables us to accompany you on a journey of discovery, to carefully develop innovative solutions for your outdated voice, mobile and data infrastructures. Understanding the past as well as being pensive about the future are as equally important as one another to achieve clarity, gain control and increase the potential for cost savings.

We have a versatile and adaptive team of telecom specialists with over 40 years of voice, data and mobile telecoms experience, which enables us to see things that others don’t see. We study your organisation, its telecoms estate and communication patterns, make sense of it all and give it meaning. We are also a Crown Commercial Service approved supplier, Cyber Essentials certified and a member of the Digital Policy Alliance.

In the Public Sector, we have assisted Local Authorities and Central Government Departments, NHS Trusts, Housing Associations, Educational establishments and the Emergency Services to move away from traditional methodologies and propel them towards more innovative applications, which are far more cost-effective, rationalised, fit for purpose and future-proofed. Conducting forensic analysis of over 200 medium to large public and private sector organisations, we have been able to achieve critical insight, clarity and cost savings in excess of £17 million per annum.

“Our dinosaur to astronaut approach enables us to accompany you on a journey of discovery.”

To quote a Chinese proverb, “a journey of a thousand miles begins with a single step.”

Gaining back control of telecoms estates that have grown exponentially over many years and no doubt inherited from a long line of administrators, can be problematic in itself. This problem has been exacerbated in recent years with COVID-19 resulting in changes to how we work, adding extra pressures for those responsible for controlling budgets and reducing costs in these new environments such as working from home, flexible working, etc. According to The Cloud Industry Forum, 70% of the workforce are now working remotely, for at least one day per week, increasing the use of video and collaborative communications and making this form of communication more important than ever as part of a Unified Communications deployment.

Segmentation Group can help you regain control of the costs incurred as these technologies evolve, identifying opportunities and independently guiding you towards the right solutions and suppliers. We can also study your communication patterns before, during and after the pandemic, to examine what effect, if any, these changes have had on your organisation.

Our independent and objective Discovery Analysis can equip you with a summary of your telecoms estate and spend, highlighting areas of concern or potential opportunity. This analysis also provides an overview of the existing legacy estate and any potential risks to your organisation of the ISDN / PSTN Switch-Off and can offer recommendations, highlighting why careful planning now for this inevitable event can mitigate exposure, whilst at the same time maximising cost savings during the digital transformation.

We fully understand that you need a baseline that you have confidence in, upon which to make business decisions for individual projects through to full digital transformation. We are also aware of all potential pitfalls that your organisation may encounter during the transition from ISDN / PSTN. According to The Cloud Industry Forum, 90% of organisations have experienced difficulties migrating to a cloud solution. We have discovered that many incumbent suppliers only advocate the move towards hosted services and IP telephony as part of a digital transformation journey, without acknowledging or helping you determine and understand legacy systems. In many cases, this may result in unnecessary and expensive solutions being proposed, which fail to encompass what is already in situ, resulting in a continuation of the lack of clarity and control that many organisations are already experiencing, even before the ISDN / PSTN networks are switched off. Segmentation Group can be the guiding light, ensuring that the past is seamlessly integrated with the future, executing an informed and successful transition, with limited cost and disruption for your organisation, both during and after this historic event.

As well as being able to assist you with the ISDN / PSTN Switch-Off, we also offer a more in-depth analysis, which is a highly detailed investigation of your entire telecoms estate and spend, including supplier contracts review and comprehensive advice on any potential improvements and cost savings. This can be further expanded to include an ongoing managed service, which provides continuous reporting on the estate inventory and costs for all current suppliers, tender support services and strategic advice, which includes detailed asset management, cost control and any other relevant observations considered necessary by our experts.

In conclusion, Segmentation Group can assist you with the ever-present need to command and control budgets and reduce costs across the whole of your telecoms estate, whether this is new and emerging technologies, for example, unified communications, or purely understanding your legacy infrastructures, to prepare for the transition from ISDN / PSTN to hosted services and IP telephony. Our ability to see things that others don’t enables us to perfectly encapsulate your needs with our knowledge, galvanising a technology infrastructure that is not only fit for purpose, but has clarity and cost control at its centre, allowing you to focus on the needs of your organisation, instead of your attention being needlessly diverted elsewhere.
