As the managing partner of a law firm, you're always balancing efficiency, compliance, and client service. Your phone system plays a surprisingly central role in all three—but if you're still relying on traditional phone systems or cobbled-together VoIP platforms, you're likely missing out on better options.

One solution many firms are exploring today is Microsoft Teams Phone—an integrated voice calling system built into Microsoft 365. If your firm already uses Teams for messaging, meetings, or file sharing, extending it to include phone service might seem like the next logical step.

But is it the right move for your firm? Let’s break down the pros and cons—and explain how a partner like Big Water Technologies can make all the difference with our BigVoice Direct Routing for Microsoft Teams.

✅ Pros of Using Microsoft Teams Phone for Your Law Firm

1. Everything in One Place
Your attorneys and staff are already using Teams to chat, meet, and collaborate. Adding phone capabilities means they can make and receive calls from the same app—on desktop, mobile, or browser—without switching tools.

2. Flexibility for Hybrid Work
Whether you're in the office, working remotely, or at a client site, Teams Phone gives your team full access to firm communications with just an internet connection.

3. Professionalism with Simplicity
Features like auto-attendants, call queues, voicemail transcription, and call recording can help your small firm present like a large, well-oiled operation—without the complexity.

4. Built-in Security & Compliance
With Microsoft’s built-in compliance capabilities (including data loss prevention, encryption, and eDiscovery), you're in a strong position to meet regulatory and ethical obligations.

5. Integration with Outlook and Calendars
Call scheduling, contact syncing, and call history all work seamlessly with your existing Microsoft 365 apps.

⚠️ Cons to Consider

1. Licensing Complexity
Microsoft’s voice licensing isn’t exactly intuitive. You’ll need Teams Phone licenses and either Microsoft Calling Plans or a Direct Routing setup (more on that below). Picking the wrong setup could mean paying too much—or missing critical features.

2. Setup and Configuration Isn’t Plug-and-Play
Voice is mission-critical, especially in a legal environment. Configuring Teams Phone for call quality, call flow, voicemail, and compliance requires a level of expertise that goes beyond just assigning licenses.

3. Support Gaps
If you go it alone, support can be slow or fragmented. You’re responsible for troubleshooting issues that impact your practice's availability and client communications.
