Digital Workplace & Collaboration

Digital Workplace & Collaboration

Collaboration your teams can rely on, wherever they work

When collaboration works, people do their best work from anywhere. Calls connect, meetings simply run, and the customer never feels the seam between front and back office.

FourNet designs and runs enterprise voice and collaboration for organisations where availability, compliance and migration safety can’t be compromised. From large-scale Microsoft Teams Voice to our UC3 platform, we deliver digital workplace solutions that perform under pressure - secure by design, on a network and security foundation we manage as one.

When collaboration is business-critical

Hybrid working is no longer experimental. It underpins frontline services, academic delivery, field operations and customer contact. Voice remains mission-critical - even as messaging and video increase.  Yet many organisations still rely on fragmented telephony estates, legacy SIP contracts, ageing PBXs and inconsistent meeting experiences. PSTN replacement introduces risk. Teams Voice promises simplicity but exposes governance, compliance and resilience gaps if deployed without proper architecture.  For regulated and public-facing organisations, failure is visible. Dropped calls, unstable migrations or weak audit controls create operational and reputational impact. Collaboration must be engineered as a controlled platform - not layered on as an upgrade.

Enterprise Teams Voice transformation delivered safely at scale for a leading university

  • Multi-site enterprise deployment across complex estates

  • Public sector and blue-light environments supported

  • Structured migration with governance, fallback and optimisation built in

A controlled, platform-led approach

Treat collaboration as a platform and it becomes something to build on – voice, video, contact and AI working together and improving year on year, rather than a fixed estate that ages. FourNet designs and runs digital workplace and collaboration as a core operational platform, not a bolt-on service.

We begin with evidence. Call flows, SIP estates, number ranges, regulatory obligations and user behaviour are mapped before any change is introduced. This creates a safe migration baseline and a clear performance benchmark.  We then design the right architecture for your context. That may include UC3 cloud communications, Microsoft Teams Voice with Direct Routing, integration with CX platforms including CXone, or optimisation of existing investments. Hosting can sit in Agile Cloud, ANTENNA, public cloud, or remain partially on-premise where required.  After go-live, our Service Delivery and Customer Success teams monitor adoption, availability, governance and optimisation opportunities - ensuring performance improves year on year, not just at launch. 

Proven performance in collaboration and migration programmes

We manage large-scale telephony transformation programmes with structured governance, ensuring continuity across complex estates while modernising core infrastructure.

  • Built on a Secure Foundation

    The platforms here run on the same secure foundation as the rest of your estate. cyber, network and AI under one accountable partner, with no seam between the network, the security and the services on top.

  • Where collaboration meets customer experience

    When service teams work in one connected environment, responses are faster and hand-offs feel seamless. We connect platforms like Microsoft Teams and UC3 with contact centre environments such as CXone, allowing agents to bring in subject-matter experts instantly during live interactions.

    For HMCTS Probate and Divorce, connecting front-office contact with back-office casework helped frontline and specialist teams work as one across high-volume, sensitive services.

FAQs

  • How is FourNet different from a typical UC reseller?

    We design and operate platforms rather than simply resell licences. That includes governance, resilience architecture, migration control and ongoing optimisation. Where appropriate, we provide FourNet-owned hosting environments alongside vendor solutions – creating accountability beyond installation.

  • Can Microsoft Teams replace our legacy PBX entirely?

    Yes, when deployed correctly. We implement Direct Routing, compliant recording, structured number management and resilience models that allow Teams to operate as a full enterprise voice platform – not just a collaboration overlay.

  • How do you reduce PSTN migration risk?

    We baseline existing estates, sequence migrations carefully, use parallel running where required and implement fallback planning. Governance around number porting and regulatory compliance is built into the delivery model.

  • Do all solutions run on Agile Cloud or ANTENNA?

    No. Hosting is selected based on your risk profile, regulatory requirements and commercial objectives. Public cloud and hybrid models remain viable options.

  • What happens after go-live?

    Structured service reviews, adoption monitoring and optimisation workshops ensure the platform continues to improve. Customer Success classification aligns effort to operational complexity and renewal timelines.

  • How does collaboration integrate with contact centre platforms?

    We integrate Teams and UC3 with CX environments such as CXone, enabling expert escalation, presence visibility and shared governance – improving resolution times and customer experience.
