Microsoft Teams Phone for Miami Businesses: A Plain-English Setup Guide

Miami's business community runs on relationships — and relationships run on reliable phone communication. Microsoft Teams Phone brings enterprise-grade calling into the Teams platform most businesses already use for chat and video meetings, eliminating the separate phone system your IT team has to maintain.

What Is Microsoft Teams Phone?

Teams Phone is a cloud PBX (private branch exchange) that adds PSTN (public switched telephone network) calling to Microsoft Teams. Users make and receive real phone calls — including calls from external landlines and mobile numbers — directly in the Teams desktop app, mobile app, or via a physical desk phone.

Licensing Options for Miami Businesses

Teams Phone with Calling Plan (all-Microsoft)

Microsoft provides both the phone system software and the PSTN calling capacity. You pay per user per month for a bundle that includes a phone number, voicemail, and a pool of calling minutes. This is the simplest option with one vendor handling everything — ideal for businesses that want minimal IT overhead.

Direct Routing (bring your own carrier)

Your business keeps its existing SIP trunk or carrier relationship, connecting it to Teams Phone via a Session Border Controller (SBC). This works well for businesses with existing carrier contracts, international calling needs, or specific number porting requirements. It requires more technical setup but offers greater flexibility and often lower per-minute costs.

What the Migration Process Looks Like

• Audit existing phone numbers and extensions — document who uses what
• Choose licensing model (Calling Plan vs. Direct Routing)
• Port existing phone numbers to Microsoft or your SIP provider (2–4 weeks for porting)
• Configure auto-attendants, call queues, and voicemail in Teams Admin Center
• Deploy and test with a pilot group of 5–10 users
• Train all staff on Teams Phone features and mobile app
• Cut over remaining users and decommission old phone system

Common Miami Business Use Cases

Professional services firms (law, accounting, real estate) benefit from call recording and compliance features. Healthcare practices use Teams Phone for patient scheduling while maintaining HIPAA-compliant messaging. Hospitality businesses appreciate the mobile app that lets staff stay reachable away from their desks.
