Whether making calls, joining meetings, or managing contacts, our step-by-step instructions will guide you through each process.

How to dial

To make a call from your MS Teams Phone:

  1. Click on the Calls icon of the left side of the application.
  2. To call a specific phone number, enter the number using the dial pad. To call a contact by name, type the person’s name into the dial pad. For group calls, enter multiple names and/or numbers in the dial pad.
    Note: As you type names or numbers, a drop-down menu will appear with potential contacts to choose from.
  3. Click Call to start the conversation.

To enter a phone number, note the following:

  • Dialing 9 before the number is no longer required

Making calls within the mainland U.S. and Canada.

All users can make calls within the mainland U.S. and Canada.

Note: Hawaii, Puerto Rico, the U.S. Virgin Islands, and similar locations are not considered part of the mainland U.S.

Dial: [Area Code] [7-digit number]

As you enter the number, Teams Phone will automatically insert the +1 prefix. This is because “1″ is the country code for the U.S. and Canada.

You can also manually add the +1 before entering the area code and number, but it is not necessary.

Making International calls

To make an International call, users must first enter the “+” (Plus).

Dial: [+] [Country Code] [Area Code] [Phone Number]

Example 1 – Calling Spain

  • Number Format: [+] [Country Code] [Area Code] [Phone Number]
  • Dial: + 34 910 58 56 48
Example 2 – Calling UK

  • Number Format: [+] [Country Code] [Area Code] [Phone Number]
  • Dial: + 44 161 425 0870

When dialing an International number, hold down the “0” key for a moment to trigger the “+” sign on the dial pad. Then, enter the rest of the numbers.
