Zoom Phone + Microsoft Teams

Smarter Communication for Modern Indian Workplaces

Empower your hybrid workforce with a unified, modern platform that works across desktops, mobiles, and locations—tailored for Indian enterprise needs.

Imagine This…

What if your team could chat, meet, and collaborate all in Microsoft Teams, and still make external business calls using a reliable, global voice platform—without switching apps?

No toggling. No delays. Just streamlined, unified communication.

Welcome to the smarter way to communicate:

Microsoft Teams + Zoom Phone Direct Routing Integration

At Operant Infotech, we don’t just keep up with change—we lead it. And this integration is a game-changer for how Indian businesses connect across states, time zones, and continents.

Why This Combo Makes Sense in India

Let’s face it—most Indian companies already rely on Microsoft Teams for meetings, chat, and collaboration. But when it comes to external calling, Microsoft Calling Plans are:

  • Expensive
  • Limited to select countries (India is not supported directly)
  • Hard to manage for businesses wanting flexibility

Enter Zoom Phone—a cloud-based voice platform that can be integrated via Direct Routing to enable business calls through Microsoft Teams, without relying on Microsoft Calling Plans.

This lets you:

  • Use Teams for everything (chat, meet, call)
  • Route calls through Zoom’s global telephony infrastructure
  • Keep your Indian numbers, SIP trunks, or cloud PBX

What Indian Businesses Love About It


One Interface. Zero Clutter.

Your users live in Microsoft Teams. Now their calling does too—no extra app required. Everything from call logs to voicemail access happens within Teams.

Use Your Existing Telephony

Already have a PRI line, SIP trunk, or cloud PBX? Keep it. We help you integrate it with Microsoft Teams using Zoom Phone as the voice layer—no need to rip and replace.

Fully Compliant & Reliable

Zoom Phone supports enterprise-grade voice features including:

  • Call queues & IVRs
  • Auto attendants
  • Call routing
  • Voicemail-to-email
  • Global PSTN breakout (for supported countries)


Note: While India phone numbers cannot be provisioned directly under Zoom Phone (as per TRAI regulations), we integrate your existing Indian SIP trunks or PBX system into Teams using Zoom's global routing engine.

Smart Scalability

From a team of 10 to an enterprise of 10,000+, this solution scales without adding on-site hardware or expensive MPLS. Perfect for companies with branches across India.

Save Big

No need for Microsoft Calling Plans (which are not available in India anyway). This hybrid setup significantly cuts licensing and hardware costs while offering full cloud telephony control.
