Why Move from On-Premise Telephony to Microsoft Teams Phone? 

Many organisations are still running on-premise phone systems that were never designed for today’s hybrid, cloud-first world. At bzb IT, we’re increasingly seeing these systems become costly to maintain, hard to secure, and restrictive for modern working. 

Microsoft Teams Phone offers a simpler, more flexible alternative that brings voice into the collaboration platform your users already rely on.

Key Benefits

  • Lower cost and complexity – No PBX hardware, maintenance contracts, or specialist telephony skills required.
  • Built into Microsoft 365 – Calling, chat, meetings, and collaboration all in one place.
  • Designed for hybrid working – Make and receive calls anywhere, on any device, using the same number.
  • Scalable and resilient – Add or remove users easily, with built-in cloud resilience.
  • Modern security – Benefits from Microsoft Entra ID, MFA, and Conditional Access.

At bzb IT, we’ve already migrated several clients to Teams Phone, helping them simplify their estates, reduce legacy costs, and improve the day-to-day experience for users. 

Why Now? 

  • On-premise systems are ageing and increasingly expensive to support. 
  • Hybrid working is no longer optional, and desk-based telephony can’t keep up. 
  • Microsoft is investing heavily in Teams Phone, while traditional PBX platforms are stagnating. 
  • Clients are looking to consolidate suppliers and reduce technical debt. 

Migrating to Teams Phone isn’t just a telephony refresh; it’s a move towards a more resilient, future-ready communications platform.
