Why it matters

Most large organisations run legacy telephony. They have on-premises PBX systems, ISDN lines, extensions managed through legacy databases. These systems work, they’ve worked for 15 years. But they don’t integrate well with modern collaboration. A message arrives in email. A follow-up conversation happens in Teams. A decision is made in a video call. Then someone picks up the phone to leave a voicemail on the PBX. The conversation fragments.

This fragmentation costs organisations time. Teams spend hours pulling together information from disparate systems. Clients get confused when they can’t tell which communication channel has the latest information. Decisions get delayed because communication is spread across platforms. The cost is invisible, it’s lost productivity, but it’s real.

Cloud-based unified communications solve this by treating communication as a single platform. Voice, video, meetings, chat, and email integrate into a single experience. A user can join a meeting and see chat history, previous emails, and participant information in one place. They can escalate a chat conversation to a video call without switching applications. They can record conversations for compliance. Everything lives in a single system with unified search, compliance, and analytics.

But moving from legacy telephony to cloud UCaaS can be complex. You need to understand your current phone system, who has extensions, what’s the current cost, what features are being used. You need to handle ISDN decommissioning and number portability. You need to migrate users and retrain them on new platforms. You need to ensure the cloud system is secure and compliant. You need to manage the transition so business users don’t lose service.

of employees say poor communication directly hurts productivity, costing them 4 hours per week in rework and repetition (Grammarly and Asana, 2024). This quantifies the cost of communication fragmentation. Every hour of lost productivity across your organisation adds up to significant cost.

Cloud telephony deployments show cost savings of up to 42 per cent compared to legacy on-premises PBX systems over five years, even before accounting for productivity gains (Forrester, 2023). This quantifies the direct financial benefit of moving to cloud UCaaS.

 Key features 

Cloud UCaaS platform deployment

We deploy cloud-based unified communications across Microsoft Teams, Cisco Webex, or RingCentral. We help you choose the right platform based on your existing infrastructure, user requirements, and integration needs. We configure the platform for your organisation, user accounts, security, compliance, integrations. We migrate users from legacy systems. We provide training so teams understand the new communication experience.

Legacy telephony modernisation

We help organisations transition from on-premises PBX to cloud telephony. This includes ISDN decommissioning, number portability, extension migration, and voicemail integration. We plan the transition to minimise service disruption. We coordinate with your telephony provider for ISDN removal and ensure continuity of service during the transition. We handle configuration of cloud phone numbers and auto-attendants so calls route correctly.

Multi-platform integration and enablement

Many organisations use multiple UCaaS platforms. We ensure consistent experience across platforms. We integrate Teams, Webex, and RingCentral with email, calendar, and business systems. We enable advanced capabilities like presence awareness so users know when colleagues are available. We establish calling policies and voicemail management so communication is consistent and compliant.

Converged Communications Managed Services

Once UCaaS is deployed, we provide ongoing managed services. We monitor voice quality and call routing. We manage user provisioning and de-provisioning. We provide automated tooling to manage number management and routing changes. We provide technical support. We help you adopt advanced features, recording for compliance, call queues for customer service, analytics for communication effectiveness. We continuously optimise so communication quality stays high.

How it works

Step 1

Current state assessment and modernisation planning

We start by understanding your current telephony environment. We audit your legacy PBX, how many extensions, what features are in use, what’s your current cost. We understand your organisation’s communication patterns and requirements. We assess your compliance and security needs. We evaluate your options, which cloud platform matches your requirements. Based on this, we build a modernisation roadmap.

Step 2

Design cloud UCaaS environment

We design your cloud UCaaS environment. We plan phone number allocation and auto-attendant configuration. We design calling policies and security. We design integration with your calendar and email so presence is automatically shared. We design for compliance, recording policies, retention, audit logging. We produce specifications so you understand exactly what’s being deployed.

Step 3

Migrate users and decommission legacy systems

We execute the migration. We migrate users from legacy extensions to cloud phone numbers. We handle ISDN decommissioning and number portability. We migrate voicemail to cloud-based voicemail. We test thoroughly to ensure call routing works correctly. We train users on new phone features, video calling, chat, presence, call recording. We provide support during the transition period so users get help when they need it.

Step 4

Establish analytics and optimisation

Once live, we offer tooling and analytics solutions so you can understand communication patterns. We track call quality, user adoption, feature usage. We identify where communication is broken, high call volumes with long wait times, features that aren’t being used, quality issues. We work with your teams to optimise, adjust call queues, enable features that drive productivity, improve routing logic.

Step 5

Ongoing managed services and continuous improvement

We provide ongoing managed services and automated tooling to monitor call quality and network performance, provision and de-provision users as your organisation changes and manage phone numbers and routing. We provide technical support. We help you adopt new features as the platform evolves. We use analytics to continuously improve communication effectiveness.

Next steps

Legacy telephony works, but it fragments communication and costs more than cloud alternatives. Cloud UCaaS isn’t just about voice – it’s about enabling communication that actually works for how your teams work today. If you’re running legacy PBX systems, the first step is understanding your current state and what modernisation could deliver.

Let’s understand your communication patterns, design a cloud UCaaS environment that matches your needs, and plan a migration that minimises disruption.

FAQs

How do we choose between Teams, Webex, and RingCentral?

Teams is the right choice for organisations already using Microsoft 365, it integrates seamlessly with email and calendar. Webex is the right choice for organisations prioritising video quality or with existing Cisco infrastructure. RingCentral is the right choice for organisations with high-volume calling requirements or contact centre operations. The right platform depends on your current technology, integration needs, and specific requirements. We help you evaluate based on your situation.

Can we migrate users gradually, or does it have to be a big bang?

Gradual migration is better when possible. You migrate some users, they get trained and comfortable, then you migrate more. This spreads disruption and allows support teams to focus. Big bang migration is sometimes necessary for technical reasons or urgent timelines. We plan the approach based on your organisation and requirements.

What happens to our current phone numbers during migration?

Phone numbers can be ported from legacy systems to cloud UCaaS. This process takes time and requires coordination with your phone service provider. In most cases, you can port your existing numbers so continuity isn’t disrupted. Some countries have regulatory requirements for number porting that take longer. We handle the coordination so the process is as smooth as possible.

How do we handle ISDN decommissioning?

ISDN decommissioning is often the most complex part of telephony modernisation. Your existing ISDN lines need to be removed, which requires coordination with your service provider. Any traffic currently routing through ISDN needs to be migrated to cloud connectivity (usually Internet). We coordinate this process to ensure service isn’t disrupted. We ensure redundancy during the transition so if the cloud connection fails, you still have service.

What about compliance and call recording?

Cloud UCaaS platforms support call recording for compliance purposes. You can configure policies so calls to certain numbers are automatically recorded, or users can manually record calls. Recordings are stored securely with access controls. Retention policies automatically delete old recordings. We help you design recording and retention policies that match your compliance requirements.

How do we measure whether UCaaS is improving communication?

We provide analytics on communication patterns and usage. You can see how frequently teams communicate, which channels they use, call quality metrics, and feature adoption. You can measure before and after, how communication patterns changed after UCaaS deployment. You can also measure business outcomes, faster decision-making, higher customer satisfaction, reduced time on meetings. These metrics help you understand whether UCaaS is delivering value.

What about phone systems for customer-facing teams?

Cloud UCaaS platforms support advanced voice features like call queues, auto-attendants, and IVR systems (interactive voice response). If you have customer-facing teams, we can design call routing that distributes calls to the right people, manages overflow, and provides professional customer experience. We can integrate with CRM systems so agents see customer information when answering calls.

Can we keep some people on legacy phones whilst others move to cloud?

Yes, hybrid telephony is common during transitions. Some people use cloud phones, others continue on legacy PBX. They can call each other normally, the systems bridge calls between cloud and legacy. This is how gradual migrations typically work. However, hybrid systems add complexity, so the goal is to move everyone to cloud over time.

How secure is cloud telephony?

Cloud telephony is highly secure. Calls are encrypted end-to-end. Access is controlled through strong authentication. Audit logs track who accessed call records. The cloud platforms invest heavily in security. In most cases, cloud telephony is more secure than on-premises PBX systems because the vendors dedicate security teams to monitoring and updating the platforms constantly.

What’s the timeline from assessment to live?

Simple deployments might be 8 to 12 weeks from assessment to live. Complex deployments with legacy decommissioning and multi-region rollout might be 6 to 12 months. The timeline depends on your organisation’s complexity, ISDN decommissioning timeline (which varies by country), and how quickly you want to migrate users. We build realistic timelines based on your specific situation.
