How We Work

From legacy PBX to Teams Phone.

Phone System Audit

We review your existing phone system, number inventory, call flows, and telephony costs. Direct Routing versus Calling Plans assessed based on your requirements and existing contracts.

02

Call Flow Design

Auto-attendant menus, call queues, and hunt groups designed with your team. Business hours, out-of-hours routing, and voicemail configured. Number porting plan produced.

03

Teams Phone Configuration

Teams Phone System licences assigned. Direct Routing or Calling Plans configured. Auto-attendants and call queues built. Desk phones provisioned where required.

04

Number Porting

Porting requests submitted to your current provider. Porting dates agreed. Temporary numbers provided during the transition window. All numbers validated post-port.

05

Testing and Validation

All call flows tested end to end. Inbound and outbound calls validated. Auto-attendant menus tested. Call quality assessed. Issues resolved before go-live.

06

Legacy Decommission

Old phone system decommissioned once Teams Phone is confirmed stable. Contracts cancelled. Hardware removed. Cost savings from legacy system elimination documented.

Real Results

Phone system migrations across Lancashire.

Professional Services Firm, Preston

A 40-person firm had an ageing on-premise PBX approaching end of support. Maintenance costs were rising and the system could not support remote workers reliably.

Teams Phone deployed with Direct Routing. All 40 DDI numbers ported. Auto-attendant and call queues configured. Legacy PBX decommissioned. Annual saving of over 12,000 pounds.

Retail Business, Blackburn

A multi-site retailer needed a single phone system across three locations with a central reception number and site-specific lines. Their existing system could not handle the complexity.

Teams Phone deployed across all three sites. Central auto-attendant routes calls to the correct site. Staff take calls on Teams on any device. Single monthly bill replacing three separate contracts.

Healthcare Provider, Burnley

A private healthcare provider needed to replace an end-of-life phone system while maintaining compliance with CQC requirements for call handling and patient communication.

Teams Phone deployed with compliant call recording. Auto-attendant configured with CQC-compliant messaging. Number porting completed without service interruption. CQC audit passed.
