Learn how to deploy audio conferencing in Microsoft Teams
Audio Conferencing is the ability to join a Teams meeting from a regular phone and dial out from a meeting to a phone number. Be sure you've reviewed Meetings rollout as part of rolling out Audio Conferencing in your organization.
Audio Conferencing deployment decisions
This article helps you decide whether to change any of the default Audio Conferencing settings, based on your organization's profile and business requirements, then it walks you through each change. We've split the settings into two groups, starting with the core set of changes you're more likely to make. The second group includes the additional settings you may want to configure, based on your organization's needs.
You only need to set up Audio Conferencing for people who plan to schedule or lead meetings. Meeting attendees who dial in don't need any licenses assigned to them or any other setup. Dialing in (calling in) to meetings is very useful for users who are on the road and can't attend a meeting using the Teams app on their laptops or mobile devices.
Audio Conferencing prerequisites
Before you can roll out Audio Conferencing for Teams, consider the following:
|Is Audio Conferencing available for my country/region?||To find out if Audio Conferencing is available for your country/region, see Country and region availability for Audio Conferencing and Calling Plans.|
|Do my users have the proper licensing for Teams Audio Conferencing?||Audio Conferencing licenses are available as part of a Microsoft 365 or Office 365 E5 subscription or as an add-on service for a Microsoft 365 Business Standard, E1, or E3 subscription.
|Do I need to purchase Communications Credits for the users who are assigned Audio Conferencing licenses?||To learn more, read What are Communications Credits, then check out the Communications Credits section below.|
Core deployment decisions
After you meet the Audio Conferencing prerequisites, complete the following tasks to configure Audio Conferencing for your users.
Teams provides a set of custom administrator roles that can be used to manage Teams for your organization. The roles provide various capabilities to administrators.
|Who will be assigned the Teams Communications Administrator role?||To learn more about Teams administrator roles see Use Microsoft Teams admin roles to manage Teams.|
|Who will be assigned the Teams Communications Support Engineer role?||To assign admin roles, see Assign administrator and non-administrator roles to users with Active Directory.|
|Who will be assigned the Teams Communications Support Specialist role?|
Conferencing bridges and phone numbers
Conferencing bridges let people dial into meetings using a phone. You can use the default settings for a conferencing bridge or change the phone numbers (toll and toll-free) and other settings, such as the PIN or the languages that are used.
See Audio Conferencing to learn more.
|Do I need to add new conferencing bridge numbers?||To add new numbers, see Getting service phone numbers.|
|Will I need to modify the bridge settings?||To modify the bridge settings, see Change the settings for an Audio Conferencing bridge.|
|Do I need to port numbers to use with audio conferencing?||To learn about porting phone numbers, read Transfer phone numbers to Teams.|
Default and alternate languages
Teams Audio Conferencing lets you set up default and alternate languages for a conferencing bridge.
|Which languages should I choose for auto attendant greetings?||To choose languages, see Set auto attendant languages for Audio Conferencing in Microsoft Teams.|
Conferencing bridge settings
After setting up your conferencing bridge, including default and alternate languages, you should verify that the default settings such as entry/exit notifications and PIN length are the ones you want to use. If they're not, you can change them.
|Will attendees hear a notification when a user joins or exits a meeting?||To change these settings, see Change the settings for an Audio Conferencing bridge.|
|What is the required length of the PIN that a meeting organizer uses to start the meeting?|
Dial-in phone number settings for users who lead meetings
After you create your Audio Conferencing bridge, you need to set the toll and/or toll-free numbers that users who lead meetings will use.
|Which conference bridge numbers will I assign to each user who leads meetings?||To assign a dial-in phone number to a user, see Step 7: Assign dial-in phone numbers for users who lead meetings.|
To provide toll-free conference bridge phone numbers and to support conferencing dial-out to international phone numbers, you must set up Communications Credits for your organization. To learn more about Communications Credits, see What are Communications Credits?.
|Are Communications Credits required for my Audio Conferencing implementation?||To find out if you need to set up Communications Credits, see Set up Communications Credits for your organization.|
|If they're required, how much should I purchase?||To determine the Communications Credits amount, see Recommended funding amounts.|
|Do I want to configure an auto-recharge amount?||To configure an auto-recharge amount, see Set up Communications Credits for your organization.|
Additional deployment decisions
You may want to change these settings, based on your organization's needs and configuration.
Outbound calling restriction policies
As an administrator, you can use outbound call controls to restrict the type of audio conferencing and end user PSTN calls that can be made by users in your organization.
|Will I limit the type of outbound calls that are allowed?||To restrict outbound calls, see Outbound calling restriction policies for Audio Conferencing and user PSTN calls.|
A dial plan, as part of Phone System in Microsoft 365 or Office 365, is a set of normalization rules that translate dialed phone numbers into an alternate format (typically E.164 format) for call authorization and call routing.
For more information about dial plans, see What are dial plans?
|Does my organization need a customized dial plan?||To help determine if you need a custom dial plan, see Planning for tenant dial plans.|
|Which users require a customized dial plan, and which tenant dial plan should be assigned to each user?||To add users to a customized dial plan using PowerShell, see Create and manage dial plans.|
Troubleshoot meeting and call quality
Teams gives you two ways to monitor and troubleshoot call quality problems: Call Analytics and Call Quality Dashboard. Call Analytics shows detailed information about the devices, networks, and connectivity related to the specific calls and meetings for each user. Call Analytics is designed to help admins and helpdesk agents troubleshoot call quality problems with specific calls, whereas the Call Quality Dashboard is designed to help admins and network engineers optimize a network. Call Quality Dashboard shifts focus from specific users and instead looks at aggregate information for an entire Teams organization.
|Who will be responsible for monitoring and troubleshooting call quality issues?||See Use Call Analytics to troubleshoot poor call quality for information about permission levels required to troubleshoot call quality issues.|
