6 Priorities for a Stronger Unified Communications Strategy
*Updated 15 September 2026*
Unified communications should do more than bring voice, messaging, video and meetings into one platform. A strong UC strategy should make communication simpler for employees, protect existing technology investments and provide the resilience, security and flexibility the organisation needs as requirements change.
This is particularly important as working patterns remain distributed. ONS research published in June 2025 found that 28% of working adults in Great Britain hybrid worked, making consistent communication across locations and devices an established business requirement.
At the same time, the UK is approaching the final stage of the PSTN retirement. Openreach confirmed in July 2026 that around 350,000 business premises were still using the legacy network, ahead of its retirement on 31 January 2027.
For organisations reviewing unified communications, six priorities can help determine the right approach.
1. Start With Users And Business Outcomes
A UC project should not begin by asking which platform to buy.
It should start by understanding how people communicate, where existing technology creates friction and which business outcomes need to improve.
Consider:
- Where employees work
- Which devices they use
- How teams communicate internally and externally
- Which applications sit alongside communications
- Where users switch unnecessarily between tools
- Which processes still depend on legacy telephony
- What needs to improve around productivity, resilience or customer experience
Microsoft's 2025 Work Trend research found that almost half of employees said their work felt chaotic and fragmented, highlighting why simply adding more communication tools does not necessarily improve productivity.
The objective should be to simplify how people communicate rather than add another application.
2. Choose The Right UC Deployment Model
Not every organisation needs the same route to unified communications.
Depending on existing infrastructure, security requirements, investment cycles and data requirements, the right model could be:
- Public cloud UCaaS
- Private cloud
- On-premise communications
- Hybrid UC
- Sovereign communications
Platforms including 8x8 Work, Zoom Phone & Collaboration Tools and Mitel MiCollab provide different approaches to voice, collaboration and cloud communications.
For organisations with greater requirements around UK hosting, operational control and data sovereignty, Britannic's Sovaris combines Mitel enterprise communications, Britannic's UK infrastructure, NetX SIP connectivity and managed services within a UK-hosted private-instance environment.
The right strategy is therefore not automatically cloud-first.
It should be outcome-first.
3. Protect Existing Investments Through Integration
A UC strategy does not always require replacing every existing communications platform.
Large organisations often operate a mixture of Microsoft Teams, Mitel, Zoom, contact centres, existing PBXs and specialist applications.
Interoperability can allow organisations to modernise in stages while retaining technology that still provides value.
Britannic's NetX Direct Routing connects platforms including Microsoft Teams and Zoom with PSTN services through the NetX SIP platform, while supporting integration with existing telephony and contact centre environments.
This gives organisations greater flexibility to change platforms or migrate users at different speeds rather than forcing a complete replacement.
4. Build Resilience And Security Into The Design
Voice remains a critical business service.
UC strategies should therefore consider what happens when a platform, connection, location or carrier becomes unavailable.
A resilience review should cover:
- Connectivity
- SIP routing
- Automatic failover
- Disaster recovery
- Fraud controls
- Role-based access
- Encryption
- Call quality monitoring
- Alternative destinations
- Business continuity testing
Britannic's NetX SIP platform provides dynamic routing, business continuity, fraud monitoring and integration across platforms including Microsoft Teams, Zoom, Mitel, Avaya and Cisco. It is backed by a 99.999% SLA.
Resilience should be designed into UC architecture from the beginning rather than added after an outage exposes a weakness.
5. Use The PSTN Retirement To Review The Wider Estate
The retirement of the analogue PSTN on 31 January 2027 is more than a line replacement exercise.
Organisations should use the migration to identify everything that still relies on legacy connectivity, including
- Telephone lines
- Lift alarms
- Payment terminals
- Fax services
- Door entry systems
- Telecare
- Security systems
- Analogue devices
Not every service will be ready for immediate migration to an IP-based alternative.
Britannic's PSTN Assure provides a managed continuity option for supported PSTN-dependent services. Using Metallic Path Facility technology, it can maintain the underlying copper connection for critical services while organisations assess, prioritise and complete their longer-term migration plans.
This can be particularly valuable across large or multi-site estates where hidden PSTN dependencies may not be identified until services are at risk.
The wider UC strategy should therefore separate two questions.
What can be modernised now?
What needs to remain operational while a longer-term migration is planned?
PSTN retirement creates an opportunity to review number management, SIP, Direct Routing, resilience and the wider communications estate while protecting critical services that cannot yet be replaced.
6. Plan For Adoption And Continuous Improvement
A UC strategy does not finish when users are migrated.
New capabilities only create value when employees understand them and the environment continues to adapt to business requirements.
Organisations should plan for:
- Pilot groups
- User training
- Adoption measurement
- Service reviews
- Call quality monitoring
- Usage analytics
- Licence optimisation
- New integrations
- AI capabilities
- Ongoing platform development
Britannic's Intelligent Managed Services and Customer Success approach focus on maintaining, reviewing and continually improving communications environments rather than simply supporting them when something goes wrong.
This becomes increasingly important as UC platforms introduce more AI, automation and workflow capabilities.
A Practical UC Strategy Framework
Britannic recommends reviewing six areas before making a platform decision.
| Priority | Key Question |
| User | How do employees actually need to communicate? |
| Platform | Which deployment model best fits the organisation? |
| Integration | What technology should be retained or connected? |
| Resilience |
|
| Migration | What legacy services still need replacing? |
| Optimisation |
|
A UC strategy should answer all six before technology selection is finalised.
Unified Communications Strategy Checklist
Before moving forward, organisations should:
- Map existing communications platforms and contracts
- Identify employee communication requirements
- Review hybrid and remote working needs
- Assess public cloud, private cloud, hybrid and on-premise options
- Identify systems that need to integrate
- Review Microsoft Teams or Zoom calling requirements
- Identify remaining PSTN services
- Assess SIP and Direct Routing options
- Test resilience and failover requirements
- Review security and fraud controls
- Consider data residency and sovereignty requirements
- Establish adoption and training plans
- Define measurable business outcomes
- Plan ongoing service reviews and optimisation
The best UC strategy is not necessarily the one that replaces the most technology. It is the one that creates a simpler, more resilient and better connected communications environment while protecting investments that still deliver value.
Britannic designs, integrates and manages unified communications environments across public cloud, private cloud, on-premise and hybrid architectures using technologies from partners including Mitel, 8x8, Zoom and Microsoft alongside Britannic's own NetX platform.
Organisations reviewing their communications strategy can book a complimentary meeting with Britannic to assess their current environment, identify migration priorities and determine the most appropriate UC approach.
