Replace your phone system. Keep your numbers.
Teams Phone replaces your traditional PBX with a cloud-based phone system built into Microsoft Teams. IP Four handles the configuration, number porting, and migration so you do not miss a single call.
Everything your phone system needs, built into Teams.
Direct Routing, Calling Plans, auto-attendants, call queues, number porting, and desk phones. Everything your business needs from a phone system, delivered through Microsoft Teams.
Direct Routing Configuration
Direct Routing connects your existing SIP trunk or telephony provider to Teams Phone. Your current numbers stay in place. Calls route through Teams on any device, anywhere.
Microsoft Calling Plans
Microsoft Calling Plans provide PSTN connectivity directly through Microsoft. Ideal for businesses without an existing SIP trunk. Numbers assigned and managed through the Microsoft 365 admin centre.
Auto-Attendants and Call Queues
Auto-attendants configured with your menu options, business hours, and out-of-hours messages. Call queues set up for reception, sales, and support lines. Hunt groups configured.
Number Porting
Your existing DDI numbers ported to Teams Phone. Porting project managed end to end. Temporary numbers provided during the porting window. No calls missed during the transition.
Teams Desk Phones and Devices
Certified Teams desk phones deployed where required. Softphone configuration for laptop and mobile users. Common area phones set up for reception and shared spaces.
Call Analytics and Reporting
Teams call analytics configured so you can monitor call quality, identify issues, and report on call volumes. Real User Monitoring enabled for proactive quality management.
From legacy PBX to Teams Phone.

Phone system migrations across Lancashire.
