Fix Teams Auto Attendant Routes Calls Wrong on a Teams Rooms Android Device

When a Teams Rooms Android device receives a call, the auto attendant may route it to the wrong destination. You expect the call to ring the front desk, but it lands on a personal voicemail or a different queue. This usually happens because the device is assigned to the wrong resource account, the auto attendant call flow points to an outdated target, or the device policy blocks the correct routing. This article explains the root cause and gives step-by-step fixes for each scenario.

You will learn how to verify the resource account, correct the auto attendant configuration, and adjust Teams Rooms policies. The fixes work in the Teams admin center and the Teams Rooms Pro Management portal. After applying them, test a call to confirm the routing matches your intended flow.

Why the Auto Attendant Routes Calls to the Wrong Place on a Teams Rooms Android Device

The auto attendant routes calls based on the call flow you define in the Teams admin center. That call flow points to a destination, which can be a user, a call queue, a resource account, or another auto attendant. When a Teams Rooms Android device is involved, the call path depends on two things: the resource account linked to the device and the destination configured in the auto attendant call flow.

A misrouting happens when one of these is out of sync. The most common cause is that the resource account on the device is not the same account that the auto attendant is trying to reach. For example, the auto attendant routes to the front desk resource account, but the Teams Rooms Android device is signed in with a different resource account, such as a conference room account. The call then goes to the wrong place.

Another cause is an outdated call flow. If you moved the front desk to a new number or a new user, but the auto attendant still points to the old destination, calls will follow the old path. The device itself does not decide the routing; it only receives the call and presents it. So the fix always starts with the auto attendant configuration and the resource account assignment.

A third cause is a policy that blocks the call. The Teams calling policy assigned to the resource account may prevent incoming calls or redirect them to voicemail. If the policy has "Make private calls" or "Call forwarding" set incorrectly, the call may never reach the device.

Steps to Diagnose and Fix Auto Attendant Call Routing on Teams Rooms Android

Follow these steps in order. Start with the auto attendant configuration, then check the device resource account, and finally review the policies. After each step, place a test call to see if the routing improves.

1. Open the auto attendant in the Teams admin center
   Go to Teams admin center > Voice > Auto attendants. Select the auto attendant that handles calls for the device. Look at the "Call flow" section. Verify the destination for the "Call routing" option. If it points to a user or a queue, note the exact name and phone number.
2. Compare the destination with the device resource account
   In the same page, click "Resource accounts" to see which resource account is linked to this auto attendant. Write down that account name. Then go to Teams admin center > Teams devices > Teams Rooms. Find the Android device. Look at the "Resource account" column. If the resource account on the device does not match the one listed in the auto attendant, that is the cause.
3. Change the device resource account (if needed)
   Select the Android device in the Teams Rooms list. Click "Edit" and change the resource account to the one that the auto attendant expects. You must have the password for the new resource account. After saving, the device will sign out and sign in with the new account. Wait for the device to restart.
4. Update the auto attendant call flow destination
   If the resource account matches but calls still go wrong, edit the auto attendant. In the call flow, change the destination to the correct user, queue, or resource account. Save the change and test.
5. Check the calling policy for the resource account
   Go to Teams admin center > Voice > Calling policies. Find the policy assigned to the resource account. Make sure "Make private calls" is set to "On" and "Call forwarding and simultaneous ringing" is set to "On". If the policy blocks incoming calls, the call may go to voicemail or fail.
6. Verify the Teams Rooms policy for the device
   In the Teams Rooms Pro Management portal, go to Device settings > Calling. Ensure "Allow incoming calls" is enabled. Also check the "Call routing" option. If it is set to "Forward to voicemail", change it to "Ring the device".
7. Restart the Teams Rooms device
   After making changes, restart the device. On the Android device, go to the Teams Rooms settings and select "Restart device". This clears any cached routing data.
8. Place a test call
   Call the auto attendant number from a phone. Verify that the call rings the Teams Rooms device. If it still goes to the wrong place, repeat the checks. Confirm the resource account on the device matches the one in the auto attendant call flow.

Method 2: Use the Teams Rooms Pro Management Portal to Reassign the Resource Account

The Teams Rooms Pro Management portal gives you a centralized view of all devices. You can change the resource account from there without touching the device locally.

1. Open the Pro Management portal
   Go to Teams Rooms Pro Management > Devices. Select the Android device from the list.
2. Edit the resource account
   Click "Edit" and change the resource account to the correct one. Enter the password for the new account. Save the change.
3. Confirm the device updates
   The portal will push the change to the device. Check the device status to ensure it shows the new resource account.

If Teams Auto Attendant Still Routes Calls Wrong

Teams Rooms Android device shows "No resource account"

If the device has no resource account, it cannot receive calls. Go to Teams admin center > Teams devices > Teams Rooms, select the device, and click "Edit". Add the resource account that the auto attendant expects. The account must have a Microsoft 365 phone system license and a phone number assigned.

Auto attendant routes to a user who is no longer active

If the destination is a user who left the company, the call will fail or go to a generic mailbox. Edit the auto attendant and change the destination to the current front desk user or a call queue. Check the user’s presence in the Teams admin center to confirm they are active.

Calls go to voicemail even when the device is ringing

This happens when the resource account has a voicemail policy that answers after a few rings. Go to Teams admin center > Voice > Voicemail policies. Find the policy for the resource account and set "Voicemail is enabled" to "Off". Or increase the "Ringing duration" to 30 seconds so the device has time to answer.

Auto attendant works on desktop but not on the Android device

The desktop client may use a different account. Check the sign-in account on the Android device. The resource account must be the same one that the auto attendant targets. Also verify that the device has an internet connection and is not in a low-power state.

Teams Auto Attendant on Teams Rooms Android vs Desktop: Key Differences

Item	Teams Rooms Android	Teams Desktop
Resource account	Assigned in Teams admin center or Pro Management portal	Uses your user account, not a resource account
Call routing	Follows the auto attendant call flow, but the device must be signed in with the correct resource account	Follows the auto attendant call flow, and the user account is always the destination
Policy impact	Calling policy and voicemail policy on the resource account affect routing	User calling policy affects routing
Device restart	Required after changing resource account	Not required

Use this table to understand why the routing differs between the two environments. The key is that the Android device relies on a resource account, not a personal user account.

Conclusion

You can now fix auto attendant misrouting on a Teams Rooms Android device. Start by verifying the resource account on the device matches the one in the auto attendant call flow. Then check the calling and voicemail policies for that resource account. After each change, restart the device and place a test call. Use the Teams Rooms Pro Management portal for remote changes. For advanced control, create a dedicated call queue for the front desk and point the auto attendant to that queue instead of a single user. This gives you better reporting and overflow options.
