Gamma’s suite of solutions, perfectly suited for the public sector

As budgets shrink and demands rise, public sector organisations are under pressure to deliver critical services required by the public, with less resource. It’s now more important than ever for these organisations to provide a seamless experience for both employees and citizens.

Gamma is in a prime position to deliver these solutions, and ensure that staff can operate more efficiently at a much lower cost. Our products are designed to support organisations in their move to cloud-based services, helping to enable hybrid working, remove the burden of on-site legacy equipment, and future-proof operations.

There’s a good reason why over 2000 public sector organisations trust Gamma as their chosen communications partner.

Prepare for the PSTN switch off

Are you ready for the biggest change impacting the public sector?

We’re all familiar with the copper wire telephone network. Having been patented by Alexander Graham Bell in 1876, it’s kept business communications going for years. But that’s all about to change…

In 2025, the Public Switched Telephone Network (PSTN) will be switched off by BT Openreach, meaning that everyone, including businesses and organisations, will have to find alternatives to PSTN-based services and find new ways to communicate.

The alternative? Voice over Internet Protocol (VoIP), a solution that transmits voice calls over an internet connection.

Why should the public sector switch to VoIP?

In 2013, the UK government adopted a ‘Cloud First’ policy, which urged organisations in the public sector to evaluate cloud-based solutions before any other solution. As the government works hard to digitally transform the public sector, cloud-based VoIP systems are standing by to make this a reality.

VoIP is far more cost-effective compared to traditional phone lines. They are easy to scale, meaning that its capabilities grow as your organisation expands, while seamlessly enabling the widespread adoption of hybrid and remote working models. The versatility of VoIP solutions means that users can multitask, increasing the daily efficiency and productivity of employees.

Let Gamma help your organisation to embrace the future of telephony by replacing your landline with VoIP before PSTN is switched off in 2025.

  • Guidance to Direct Award (Network Services 2 RM3808)

    The Network Services 2 (RM3808) framework agreement offers organisations a range of Telecommunication and ancillary services across 13 lots. This framework allows organisations to select services by Direct Award or Further Competition. 

    Direct award is available on all 13 lots, where supplier Service Offers are shown in the Government eMarketplace catalogue, and offers a quick and flexible way to procure services from an approved supplier on the framework.

  • Is Direct Award compliant?

    Yes, purchasing services via Direct Award is fully OJEU compliant, without the need to run a Further Competition. All suppliers who list services on the Government eMarketplace for Direct Award are fully approved by the CCS, so organisations considering Direct Award can purchase in confidence.

  • When is Direct Award suitable?

    If you know the services you require, the Direct Award route offers organisations the ability to identify, evaluate and select suitable service offers in a catalogue format. This is a CCS approved procurement route and can help organisations purchase services more quickly and without the need for a lengthy Further Competition process.

  • When may Direct Award not be suitable?

    For more complex requirements, or when you require bespoke requirements or Special Terms, the Further Competition route should be used.

    Our specialist consultants can offer additional guidance on when the Further Competition route may be more suitable.

  • How do I use Direct Award?

    Live Service Offers from approved suppliers can be found in the technology catalogue in the Government eMarketplace, where you can search, evaluate and select the Services required. Your organisation will need to register as a Buyer to be able to access the catalogues. More information on registering can be found here.

    Once you have completed your evaluation of the relevant Service Offers, you can place an order for your chosen offer by completing the Call-Off Order Form. More guidance here

  • What if I cannot find a suitable Service Offer?

    If after searching the catalogue you are unable to find a suitable Service Offer for your organisation’s requirements, you can issue a Request for Information (RFI) to all the Suppliers on the chosen lot. Approved Suppliers then have the opportunity to respond with an existing Service Offer, or can upload a new Service Offer to the catalogue to meet your requirements.

  • What are the reasons citied by customers for using Gamma?

    When we introduce our offerings – such as Horizon, SIP or Unified Comms – into public sector organisations, it drives out huge amounts of costs and turns highly complex organisations into easy-to-manage infrastructures.

  • Why should we choose Gamma?

    Because we know that public sector procurements are now all about achieving specific outcomes; it is not about the technologies, products and solutions used to achieve them. This approach does not suit entrenched legacy suppliers who are unable to match the agility of vendors like Gamma.

  • How can you help us achieve the outcomes we need?

    We seek to engage with your long-term ICT strategy and provide a transparent route to procurement, delivery and ongoing management. We understand the budget pressures you are facing and will work with you to increase the impact of every pound you spend, making your budgets go further.

  • How can you help with flexible working?

    Gamma’s solutions offer intelligent call routing, fixed/mobile integration and unified communications. These can be integrated with Microsoft Skype® for Business and leading CRM tools such as Salesforce to help your staff work and collaborate more effectively.

  • What customer services do you offer?

    Support is provided by our friendly, UK-based team and is available 24×7. Also bear in mind that more than 98% of our customers remain with us after the first year of service, one of the highest retention rates in the industry.
