We are pleased to share that Cisilion has achieved the Calling for Microsoft Teams Specialization, further strengthening our credentials as a trusted partner for modern, cloud-based communications.
This specialisation recognises partners with proven expertise in delivering Microsoft Teams Calling at scale. It validates not just technical capability, but real-world customer outcomes, operational excellence and a consistent track record of successful deployments.
Why the Calling for Microsoft Teams Specialization matters
Microsoft Teams has become the hub for collaboration across organisations of all sizes. As businesses increasingly retire legacy telephony and PBX platforms, Teams Calling plays a critical role in enabling secure, flexible and resilient voice services.
The Calling for Microsoft Teams Specialization demonstrates that a partner can:
- Design and deploy enterprise-grade Teams Calling solutions
- Migrate complex voice environments with minimal disruption
- Integrate PSTN, contact centre and advanced calling capabilities
- Deliver secure, compliant and reliable services across hybrid and cloud estates
- Support customers through adoption, optimisation and ongoing management
Achieving this status requires rigorous assessment by Microsoft including customer references and evidence of successful, repeatable delivery.
What this means for our clients
For our clients, this specialisation provides independent assurance that Cisilion has the experience and capability to support voice transformation with confidence.
Whether organisations are:
- Replacing legacy telephony
- Consolidating collaboration tools
- Supporting hybrid and remote working
- Improving resilience and call quality
- Integrating Teams Calling with wider Microsoft 365 and security strategies
Our team can design solutions that align with both technical requirements and business outcomes.
Built on real-world delivery experience
Cisilion has been delivering Microsoft Teams Voice and Calling solutions for years across a range of industries including regulated sectors and complex enterprise environments.
This specialisation reflects the depth of our engineering expertise, our structured delivery approach and our focus on long-term customer value rather than short-term implementation.
Looking ahead
As voice continues to converge with collaboration, security and AI capabilities within Microsoft Teams, the importance of getting the foundations right has never been greater. This achievement reinforces our commitment to helping organisations modernise communications safely, securely and at scale.
