Frequently Asked Questions
What is PSTN calling in Microsoft Teams?
PSTN (Public Switched Telephone Network) calling in Microsoft Teams enables users to make and receive traditional phone calls directly from the Teams application. It turns Microsoft Teams into a full enterprise phone system, replacing legacy PBX hardware with cloud-based telephony.
What licensing is required for Teams Phone System?
Teams Phone System requires a Microsoft 365 E5 license (which includes Phone System) or a Microsoft 365 E1/E3 license with a Teams Phone add-on ($8/user/month). Additionally, you need either a Microsoft Calling Plan, Operator Connect, or Direct Routing to connect to the PSTN network.
What is the difference between Calling Plans and Direct Routing?
Microsoft Calling Plans are a fully cloud-based solution where Microsoft provides the phone numbers and PSTN connectivity. Direct Routing connects your own SBC (Session Border Controller) and telecom provider to Teams, offering more flexibility, potentially lower costs for large deployments, and the ability to keep existing carrier contracts.
Can I port my existing phone numbers to Microsoft Teams?
Yes, you can port existing phone numbers to Microsoft Teams whether using Calling Plans or Direct Routing. The porting process typically takes 2-4 weeks depending on your current carrier and number complexity. EPC Group manages the entire porting process to ensure zero downtime during the transition.
Does Microsoft Teams support E911 emergency calling?
Yes, Microsoft Teams supports Enhanced 911 (E911) calling with dynamic emergency calling capabilities. Teams can detect user location and route emergency calls to the appropriate Public Safety Answering Point (PSAP) with accurate location information, meeting regulatory requirements for enterprise phone systems.

Microsoft Teams Strategy: 2026 Considerations for Pstn Calling In Microsoft Teams
Microsoft Teams Phone in 2026 is the modern enterprise PSTN replacement: Teams Phone Standard ($8/user/mo) for outbound calling via Microsoft Calling Plans, Teams Phone with Calling Plan Domestic ($15/user/mo) bundles 3,000 outbound minutes/user/mo, and Operator Connect lets enterprises retain incumbent carriers (BT, Verizon, Lumen) while integrating natively with Teams. The total-cost comparison vs legacy PBX favors Teams Phone for any deployment over 500 users.
Teams Rooms (Microsoft Teams Rooms Pro license at $40/room/mo) brings governance, security, and remote management to conference-room hardware in 2026. Compared to dumb HDMI projectors, the per-room cost is offset within 12-18 months by reduced AV-support helpdesk volume, automatic firmware patching, and Microsoft Endpoint Manager-driven device compliance. Healthcare and financial services deployments typically standardize on Logitech Rally or Yealink for the room hardware.
Decision factors EPC Group evaluates
- Communication Compliance policies for executive and regulated roles
- Teams Rooms hardware standardization (Logitech Rally vs Yealink)
- Microsoft Purview information barriers for cross-business-unit segregation
- Microsoft Sentinel detections for Teams compliance recording requirements
- Teams Phone Standard vs Calling Plan vs Operator Connect TCO comparison
