I can’t make calls in Operator Connect

This page can help you diagnose and resolve common issues that prevent users from making outbound calls using Operator Connect.

Suggested help

User can’t make outbound calls in Teams

This often happens when the user does not have the correct licence or calling permissions.

Solution:

  • Check the user has a Teams Phone licence assigned.
    1. Go to Microsoft 365 Admin Centre
    2. Select Users > Active users
    3. Choose the user
    4. Select Licences and apps
    5. Confirm Teams Phone is assigned
  • Confirm the user has a valid Operator Connect phone number assigned.
    1. Go to Users > Active users
    2. Select the user
    3. Under Account, look for Usage location
    4. Ensure it is set to the correct region
    5. Ensure the user is not blocked by a Teams Calling Policy that restricts outbound calls.

Dial pad is missing in Teams

This usually indicates that the user is not fully enabled for calling.

Solution:

  • Assign a Teams Phone licence. See Getting and assigning a Teams Phone license.
  • Confirm the user has a phone number assigned through Operator Connect.
    1. Go to Teams Admin Centre
    2. Select Users > Manage users
    3. Choose the user
    4. Under Account, look for Phone number
    5. Confirm that a valid Operator Connect number is assigned

User receives ‘We can’t connect your call’

This can happen when the number format is incorrect or the call is being blocked by routing rules.

Solution:

  • Make sure the user is dialling in E.164 format (e.g., +44 20 1234 5678).
  • Check that the number being dialled is valid and reachable.
  • Confirm that outbound call routing is configured correctly for Operator Connect.

Outbound calls fail for all users

This may indicate that Operator Connect is not active or the tenant is not fully linked to BT.

Solution:

  • Check that Operator Connect appears as active in the Teams Admin Centre.
  • Make sure all steps in the Setting up Operator Connect process are complete.
  • If the service still does not appear, contact our support team to confirm your tenant is linked.

User has a number assigned but still can’t make calls

This can happen if the number is not fully provisioned or synced.

Solution:

  • Remove the number from the user and reassign it.
  • Wait a few minutes for Teams to sync changes.
  • If the number still does not work, contact our support team to confirm provisioning.

Calls fail after porting numbers to BT

Ported numbers may take time to fully activate across all carriers.

Solution:

  • Allow time for porting to complete (typically up to 24 hours).
  • If calls still fail, contact our support team to check the porting status.

User can receive calls but cannot make calls

This often indicates an outbound routing or policy issue.

Solution:

  • Check the user’s Voice Routing Policy (if applicable).
  • Confirm the user is assigned to the correct Operator Connect calling profile.
  • Verify that outbound calling is not restricted by a Teams Calling Policy.
