The complete guide for businesses that want customer-facing toll-free numbers routed directly into Microsoft Teams.
For organizations using Microsoft Teams as their core phone system, providing customers with a frictionless, free-to-call contact method is essential.
Whether you operate a support desk, sales line, service center, or global customer operation, a Microsoft Teams toll-free number makes your business more accessible while keeping all inbound calls inside Teams.
This guide walks IT and telecom leaders through everything needed to purchase, configure, and manage Microsoft Teams toll-free numbers, including pricing models, routing options, use cases, and how to choose the right provider.
What Is a Microsoft Teams Toll-Free Number?
A Microsoft Teams toll-free number is an inbound business phone number that customers can call at no cost, with calls delivered directly into Teams via Auto Attendants, Call Queues, or individual users.
Your organization pays the inbound usage charges, while callers enjoy a seamless, professional way to contact your business.
Common toll-free prefixes include:
- 0800 / 0808 (UK)
- 1-800 / 888 / 877 (US & Canada)
- 1800 / 1300 (Australia)
- Region-specific prefixes across 70+ countries

Why Businesses Add Toll-Free Numbers to Microsoft Teams
While Microsoft Teams centralises internal communication, customers still expect fast, reliable phone access to your organization. A toll-free number integrated into Teams removes friction for callers and strengthens your customer experience. A Microsoft Teams toll-free number offers several key advantages:
1. Improve Customer Accessibility
Customers are more likely to call when the number is free—crucial for:
- Customer support
- Technical helpdesks
- Sales and enquiries
- Billing and accounts queries
Removing the cost barrier increases customer engagement and satisfaction.
2. Route All Inbound Calls into a Single Platform
With Teams as your core voice system, toll-free numbers can be routed to:
- Call Queues
- Auto Attendants

- Direct users or hunt groups
Employees stay within Teams, reducing complexity and operational overhead.
3. Expand Internationally With Local Toll-Free Numbers

- Cost allocation by number or department
- Usage across countries or services
This empowers IT and Finance teams to optimiz
e spend and performance.
Microsoft Teams Toll-Free Number Pricing
Understanding the cost of a Microsoft Teams toll-free number can be confusing because Microsoft and telecom providers follow different models. Below we break down the two typical approaches so IT leaders can choose the one that aligns with their budget and usage patterns.
Here’s what IT admins need to know:
Option 1: Microsoft’s Native Toll-Free Numbers (Limited Availability)
Microsoft offers a small range of toll-free numbers through Calling Plans. Pricing typically involves:
- Monthly fee per toll-free number
- Per-minute inbound usage charges
- Higher international access rates
- No flat-rate pricing options
There are also dialing limitations and restrictions to be aware of. For multi-country organizations, this model is usually not scalable or predictable.
Option 2: Callroute Toll-Free Number Pricing (Predictable & Global)
Callroute offers a transparent, enterprise-ready pricing model for toll-free numbers routed into Microsoft Teams:
- Flat monthly fees
- Optional bundled minutes
- Global availability across 70+ countries
- No hidden surcharges
- Real-time cost reporting
For organizations with international customers or predictable budget requirements, Callroute’s flat-rate or bundled pricing models offer far greater control than Microsoft’s limited, variable-rate toll-free options.

How to Add a Toll-Free Number to Microsoft Teams
Microsoft Teams does not natively support global toll-free number provisioning through its Calling Plans, and Microsoft’s own toll-free inventory is extremely limited. Because most organizations require numbers in multiple countries—or more flexible routing than Microsoft provides—the majority of enterprises choose to bring toll-free numbers into Teams through a carrier.
This approach requires Direct Routing, which allows inbound toll-free calls from any country to be delivered into Microsoft Teams and routed to the correct users, queues, or services.
Direct Routing (The Standard Method for Toll-Free Numbers)
Direct Routing uses a certified SBC and SIP connectivity to route calls from your carrier—such as Callroute—into your Teams environment.
Benefits of Direct Routing for toll-free numbers:
- Works with numbers from 70+ countries
- Full routing flexibility (Queues, Auto Attendants, users, mobiles, SIP endpoints)
- No reliance on Microsoft’s limited toll-free inventory
- Supports complex telephony environments or hybrid setups
- Allows mixing toll-free and geographic numbers in one solution
- Enables bulk provisioning and global management through Orto
Direct Routing is the only method that gives organizations global reach, enterprise control, and consistent numbering management for toll-free services in Microsoft Teams.

How Callroute Compares to Other Providers
Many providers can supply toll-free numbers, but far fewer can deliver them reliably into Microsoft Teams with the flexibility, global coverage, and cost transparency that enterprise organizations require.
The table below highlights how Callroute differs from both traditional carriers and Microsoft’s limited native offering.
| Feature | Callroute | Traditional Carrier | Microsoft |
| Global toll-free numbers | ✅ 70+ countries | ⚠️ Limited | ❌ Very limited |
