Unified Communications
Keep Your Communications Data Where It Belongs.
Unified communications systems that give you full control over data location, access, and retention - without routing sensitive traffic through external cloud services you didn't approve.

Take Back Control of Business Communications Before It Costs You More
When communications spread across too many tools and unmanaged routes, something breaks: calls drop, context disappears, and accountability gets blurred. The hidden cost shows up fast - slower decisions, duplicated admin, inconsistent customer experiences, and growing exposure to data and compliance risk.
The fix is not another off-the-shelf platform bolted on top. What's needed is a bespoke communications foundation that integrates with existing identity, workflows, and systems - keeping data where it should be, enforcing policy by design, and making day-to-day communication reliable again. The longer fragmentation is left in place, the more expensive it becomes to untangle.
Here's what that looks like in practice:
- Consolidate voice, video, messaging, and collaboration into a single governed platform
- Keep data residency, retention, and access policies under direct control
- Integrate with CRM/ERP/helpdesk and existing identity providers to reduce manual handoffs
- Build resilient routing and capacity planning that scales with demand
- Apply encryption, least-privilege access, and audit-ready logging from day one
- Design for real-world exceptions, not perfect inputs, with clear operational ownership
If communication is now a business-critical dependency, the next step is to map the architecture and agree the controls, integrations, and outcomes - then build towards them. Schedule a Consultation.

Corporate Enterprises
Centralise internal collaboration and client communication with tools that integrate into CRM, ERP, and project management systems.
From Fragmentation to Control: How We Deliver
We create Unified Communications platforms that match how your teams work. Our approach combines structured planning, open-source expertise, and careful integration to deliver reliable, scalable systems.
-
Current-State Discovery
We begin by reviewing how your teams communicate today - including user groups, call paths, collaboration habits, security requirements, and any links to platforms such as CRM or ERP. This step highlights constraints, improvement opportunities, and the capabilities the solution must deliver in day-to-day use.
-
Blueprint & Technical Design
From the discovery findings, we create a clear architecture that maps out how calling, messaging, video, and file services will work together. Component choices are made with longevity in mind - keeping the design modular, reducing unnecessary vendor lock-in, and allowing the platform to scale as your needs grow.
-
Build, Configure & Integrate
Our team implements and connects the chosen components into a single, cohesive platform aligned with your workflows. We configure routing logic, messaging structures, conferencing behaviour, identity integration, and access controls, adding tailored features where needed so the system supports how your users actually operate.
-
Roll-Out & Continuous Support
We roll out in controlled phases to keep disruption low, validating performance and user experience at every step. You receive practical documentation and onboarding support to drive adoption, backed by SLA-Based Technical Support and Dedicated Support Hours resources to ensure reliability.
Why Choose Onyxsis?
Proven Results You Can Point To
Evidence-backed outcomes, made visible.
We back our engineering with evidence, not promises, and we make the outcomes visible so you can justify the investment internally. Our case studies show what happens when complex communications challenges are tackled properly, end to end.
In our Contact Centre Operations Hub work for a leading UK telecoms provider, we helped deliver a 42% increase in first-call resolution and an 11% rise in NPS within 12 months. Those results came from turning fragmented operational insight into clear, actionable workflows that teams could rely on day after day.
What that demonstrates is a communications foundation built for accountability, reliability, and real operational ownership.
A Partner That Puts You in Control
We are an open-source business at heart, and we bring that independence into every relationship. You get straight answers, transparent options, and a partner that designs for long-term control rather than short-term dependency.
