How to modernise your business phone system

A practical migration framework for moving off legacy telephony.

Modern cloud IP handsets replacing legacy PBX hardware in a UK office

Modernising a business phone system isn't just swapping handsets. It's an opportunity to remove operational friction, consolidate vendors and prepare for AI - without disrupting live services.

A practical migration framework

  • Audit current numbers, DDIs, call flows and integrations
  • Map who actually answers which calls today
  • Choose a target platform - cloud PBX, Teams-native, or hybrid
  • Port numbers in phased groups to reduce risk
  • Retire legacy lines and ISDN once traffic has moved

Common pitfalls to avoid

  • Under-scoping CRM and helpdesk integrations
  • Skipping call-quality testing on the new circuit
  • Leaving analogue devices (fax, alarms, lifts) unplanned
  • Not training front-of-house users before go-live
