Embrace Modern Voice Solutions Integrated with Microsoft Teams
Say Goodbye to Legacy Phone Systems
Simplify communications, cut costs, and unlock advanced features with Otto IT’s future-ready voice and contact centre solutions.

Why Make The Switch?
Legacy platforms like Mitel or high-cost UCaaS providers such as RingCentral are holding businesses back. Common pain points include:
Rising maintenance costs and ageing hardware, complex dial plans and fragmented versions across sites, limited integration with Microsoft 365 and collaboration tools, premium pricing models that spiral as you scale, poor support for hybrid work and modern CX features. If this sounds familiar, it’s time for a smarter alternative.

- Leverages your existing Microsoft 365 investment
Option 2: Advanced UCaaS & Contact Centre Integrated with Teams
- Rich voice and omni-channel customer engagement
- AI-powered routing, analytics, and reporting
- Ideal for businesses with complex call handling or formal contact centres
