Fix Teams Call Queue Does Not Ring in Teams Admin Center

When a Teams call queue stops ringing, callers hear a busy tone or get disconnected. This issue typically appears after a policy change or a resource account misconfiguration. The problem often stems from the call queue’s routing settings, agent assignment, or the associated resource account being unlicensed. This article explains the root causes and provides step-by-step fixes to restore call queue ringing.

You will learn how to verify the resource account, check call queue settings, and test the routing. We also cover common related failures, such as agents not receiving calls or the queue being paused. By the end, you can resolve most call queue ringing issues from the Teams admin center.

Why a Teams Call Queue Stops Ringing

A call queue in Teams routes incoming calls to a group of agents. When it does not ring, the cause is usually one of three things: the resource account is not properly licensed, the call queue is paused, or the routing settings are misconfigured. Each of these issues can interrupt the call flow silently, so callers may not receive an error message.

The resource account acts as the caller ID and the entity that owns the call queue. If this account lacks a Teams Phone license or a phone number, the call queue cannot accept calls. Similarly, if the call queue is paused, the system rejects incoming calls immediately. Routing settings determine how calls are distributed; if the routing method is set to “Attendant” but no agents are assigned, the queue will not ring.

Another common cause is a conflict with the calling policy. The default calling policy allows inbound calls, but a custom policy may block them. Also, if the call queue is assigned to a resource account that is also used for an auto attendant, the call flow can break. Understanding these causes helps you diagnose the issue quickly.

Steps to Diagnose and Fix the Call Queue Ringing Issue

Follow these steps in order to identify and fix the problem. You need access to the Teams admin center and the appropriate admin roles, such as Teams Administrator or Global Administrator.

1. Check if the call queue is paused
   Go to Teams admin center > Voice > Call queues. Select the call queue that is not ringing. In the pane, look for the “Call queue status” field. If it says “Paused,” click “Resume” to activate it. If it is already active, proceed to the next step.
2. Verify the resource account license
   Go to Teams admin center > Users > Resource accounts. Find the resource account associated with the call queue. Click on the account and check “Assigned licenses.” It must have a Teams Phone license. If not, assign one. Also confirm that the account has a “Phone number” assigned under “Phone numbers.” If the number is missing, add one.
3. Confirm the routing method and agents
   Back in the call queue settings, go to “Routing method.” Ensure it is set to “Attendant,” “Serial,” “Longest idle,” or “Round robin.” Then check “Agents” to see if any users are listed. If no agents are assigned, add them. Also verify that the agents are not blocked from receiving calls due to their own call forwarding or do not disturb settings.
4. Review the calling policy
   Go to Teams admin center > Voice > Calling policies. Select the policy assigned to the resource account. Under “Inbound call routing,” make sure “Allow inbound calls” is enabled. If it is set to “Disable,” change it to “Enable” and save. Also check that the policy does not have “Call forwarding” set to “Blocked.”
5. Test the call queue with a direct call
   After making changes, call the phone number of the resource account. If it rings now, the issue is resolved. If not, check the “Call queue” settings again for any red flags. Also verify that the resource account is not also assigned to an auto attendant, which can cause a conflict.

If Teams Call Queue Still Does Not Ring

If the queue still does not ring after the main fix, there are a few additional things to check. These issues are less common but can cause the same symptom.

Call queue agents are not receiving calls

Sometimes the call queue rings, but agents do not see the call. This happens when agents have their presence set to “Do not disturb” or have call forwarding enabled to another number. Instruct agents to set their presence to “Available” and disable call forwarding. Also check that agents have a Teams Phone license and are not using the free version of Teams.

Call queue is assigned to a resource account without a phone number

The resource account must have a phone number that is assigned to the call queue. If the number is missing, the call queue cannot receive calls. To fix this, go to Teams admin center > Voice > Phone numbers. Assign a number to the resource account. Then go back to the call queue and verify that the number is listed under “Resource account.”

Call queue is not saved after editing

If you make changes but forget to click “Save” at the bottom of the call queue settings, the changes are lost. Always look for the “Save” button and click it after any modification. You can also check the “Activity” log in the Teams admin center to see if your changes were recorded.

Teams Call Queue Settings: Desktop vs Admin Center

Item	Teams Admin Center	Teams Desktop App
Purpose	Configure and manage call queues	Make and receive calls
Access	Web browser, admin credentials	Installed client, user sign-in
Key settings	Routing method, agents, resource account	Presence, call forwarding
Typical user	IT admin	End user

The admin center is where you fix the call queue. The desktop app is where agents manage their own availability. Both are necessary for a smooth call queue experience.

You now know how to fix a Teams call queue that does not ring. Start by checking the call queue status and the resource account license. Then adjust the routing method and calling policy. Test the queue after each change to confirm the fix.

Next, review your call queue’s agent list to ensure all agents are active and available. Also consider setting up call queue analytics to monitor future issues. Use the Teams admin center’s “Activity” log to track changes and identify problems early.
