Including a dial-in number in your Microsoft Teams meetings ensures that participants can join via phone, regardless of their internet connection or device. This guide covers how to add dial-in numbers, the benefits of doing so, and how to choose the right options for your organization. Whether you’re an IT admin setting up large-scale meetings or a team leader looking to improve accessibility, this article provides step-by-step insights and practical tips.
1. Enable Audio Conferencing Licenses in Microsoft 365
Before you can add dial-in numbers to your Teams meetings, your organization needs to have the appropriate Audio Conferencing licenses. These licenses, such as Microsoft 365 E5 or the standalone Audio Conferencing add-on, enable the dial-in capabilities for meetings. Assigning licenses to users allows them to generate meeting invitations that include a phone number and conference ID, making it easy for participants to join by phone. Without these licenses, the dial-in option won’t be available, so ensure your admin has purchased and allocated the necessary licenses.
2. Set Up a Dial-in Number in the Microsoft Teams Admin Center
Once licenses are in place, administrators can add dial-in numbers through the Microsoft Teams Admin Center. Navigate to the ‘Voice’ section, then ‘Phone numbers,’ and select ‘Add.’ You can assign existing phone numbers or request new ones from Microsoft or your telephony provider. These numbers are associated with your organization and can be geographic or toll-free, depending on your needs. Properly configuring these numbers ensures participants from various regions can join easily without incurring international charges.
3. Assign Dial-in Numbers to Meetings
After setting up the phone numbers, you need to assign them to specific meetings or users. When scheduling a Teams meeting via Outlook or Teams, select the ‘Meeting options,’ then ensure the ‘Require dial-in’ feature is enabled. Participants will see the dial-in number and conference ID in the meeting invite. For recurring meetings, you can set default dial-in numbers for the organizer or specific teams, streamlining the process and ensuring consistency across meetings.
4. Customize Dial-in Numbers for Different Regions
If your organization operates globally, offering region-specific dial-in numbers improves accessibility and reduces costs for participants. Microsoft allows you to add multiple numbers for different countries or regions, which can be embedded automatically into meeting invites based on the participant’s location. This customization minimizes international calling charges and enhances user experience by providing local access options.
5. Use the Microsoft Teams Dial-in Conferencing Feature
The dial-in conferencing feature integrates seamlessly with Teams, providing a unified experience. When a meeting is scheduled with a dial-in number, attendees can join via the provided phone number and conference ID, even if they don’t have internet access. This feature is particularly useful for participants who are on the move or in areas with unreliable internet connectivity, ensuring inclusivity and flexibility during meetings.
6. Monitor and Manage Dial-in Usage
Administrators can track how often dial-in numbers are used through the Microsoft Teams Admin Center or PowerShell commands. Monitoring usage helps you understand the demand for phone access, manage costs, and identify any potential security issues like unauthorized access. Regular review of dial-in activity ensures your organization maintains control over meeting participation and can optimize the setup accordingly.
7. Promote Dial-in Options to Participants
To maximize participation, communicate clearly in your meeting invites that dial-in options are available. Include the phone number, conference ID, and any necessary PINs or access codes. Providing this information upfront ensures participants know how to join, especially those who may have limited internet access or prefer joining via phone. Clear instructions reduce confusion and help meetings run smoothly.
8. Integrate with Third-Party Telephony Providers
If your organization uses a third-party telephony provider like Cisco or Avaya, you can integrate their services with Microsoft Teams to offer dial-in numbers. This allows for more control over call costs, number selection, and regional coverage. Integration typically involves configuring Direct Routing within Teams, enabling your organization to leverage existing telephony infrastructure while maintaining the benefits of Teams meetings.
9. Consider Toll-Free vs. Local Numbers
Choosing between toll-free and local numbers depends on your organization’s needs and participant locations. Toll-free numbers are convenient for participants who might be concerned about call charges, but they often come with higher setup costs. Local numbers, on the other hand, reduce international calling charges for participants and can be more accessible in specific regions. Evaluate your budget and participant locations to select the most suitable option.
10. Regularly Review and Update Your Dial-in Numbers
As your organization grows or changes, so should your dial-in setup. Regularly review your assigned numbers, usage statistics, and regional needs to ensure optimal coverage. Updating or adding new numbers as needed helps maintain accessibility and control costs, ensuring your Teams meetings remain inclusive and efficient over time.
How to Choose
When selecting dial-in numbers for your Microsoft Teams meetings, consider factors like geographic coverage, call costs, and participant convenience. Determine whether toll-free or local numbers better suit your organization’s needs, and ensure the numbers are easy to remember and accessible. It’s also critical to evaluate your existing telephony infrastructure and whether integration with third-party providers is necessary. Finally, think about scalability; choose options that can grow with your organization without requiring frequent reconfiguration.
