Cross-company calling

With the May release of Dynamics 365 Remote Assist, you can use the app to call an expert in another company. To search for contacts outside your company directory, just enter the contact's full email address to find them and make the call.

To set up cross-company calling, your company and the company of the person you’re calling both have to enable external access in the Teams admin center. For information, see Set up cross-company calling for Dynamics 365 Remote Assist. See also Manage external access (federation) in Teams.

There are two current limitations with cross-company calling:

  • This feature is available only for one-to-one calls (no group calls yet).
  • File sharing is disabled due to a technical constraint with Microsoft Teams.

For information on making a cross-company call, see the Dynamics 365 Remote Assist User guide.
