    Microsoft Teams

This article describes considerations for emergency calling for Microsoft Calling Plan users. Before reading the rest of this article, make sure you've reviewed critical emergency calling concepts and definitions in Plan and manage emergency calling.

To find out if Microsoft Calling Plans are the right solution for your business, see PSTN connectivity options and Microsoft Calling Plans for Teams.

Emergency call enablement for Calling Plans

Each Calling Plan user is automatically enabled for emergency calling and is required to have a registered emergency address associated with their assigned telephone number.

When the location is associated to the telephone number depends on the country/region:

  • In the United States and Canada, for example, an emergency location is required when a number is assigned to a user.

  • For other countries/regions—such as in Europe, the Middle East, and Africa (EMEA)—an emergency location is required when you get the phone number from Microsoft 365, or when it's transferred from another service provider or carrier.

Dynamic emergency calling for Calling Plans

Dynamic emergency calling for Calling Plans provides the capability to configure and route emergency calls based on the current location of the Teams client. The ability to do automatic routing to the appropriate Public Safety Answering Point (PSAP) or to notify security desk personnel varies depending on the country/region of usage of the Teams user.

Dynamic location for routing emergency calls is supported in the United States as follows.

  • If a Teams client for a United States Calling Plan user dynamically acquires an emergency address within the United States, that address is used for emergency routing instead of the registered address, and the call will be automatically routed to the PSAP in the serving area of the address.

  • If a Teams client for a United States Calling Plan user doesn't dynamically acquire an emergency address within the United States, then the registered emergency address is used to help screen and route the call. However, the call will be screened to determine if an updated address is required before connecting the caller to the appropriate PSAP.

Dynamic location for routing emergency calls is supported in Canada the same as in the United States with the following exception: all emergency calls will be screened nationally before being transferred to the PSAP.

For more information, see Plan and configure dynamic emergency calling.

Emergency call routing for Calling Plans

When a Teams Calling Plan user dials an emergency number, how the call is routed to the PSAP depends on the following:

  • Whether the emergency address is dynamically determined by the Teams client

  • Whether the emergency address is the registered address associated with the user's phone number

  • The emergency calling network of that country/region

For example:

In the United States:

  • If a Teams client is located at a tenant-defined dynamic emergency location, emergency calls from that client are automatically routed to the PSAP serving that geographic location.

  • If a Teams client is not located at a tenant-defined dynamic emergency location, emergency calls from that client are screened by a national call center to determine the location of the caller before transferring the call to the PSAP serving that geographic location.

  • If an emergency caller is unable to update their emergency location to the screening center, the call will be transferred to the PSAP serving the caller's registered address.

In Canada, Ireland, and the United Kingdom, emergency calls are first screened to determine the current location of the user before connecting the call to the appropriate dispatch center.
