'Additional Call Redirected' Status to Xiaomi: Transcription and Solution

Owners of Xiaomi smartphones with a MIUI shell or HyperOS often encounter unclear statuses in the status bar or when making calls. One such message is the phrase “Additional call forwarded.” This notification can appear both during the conversation and in call logs, causing confusion for the user who has not configured any complex routing schemes.

In fact, this function is a standard element. GSM-A redirect in this context means that the network automatically redirects the second caller to a voicemail or other number because you were having a conversation. Understanding how this service works will help you better control your communications.

In this article, we will discuss in detail why the system is giving out such a message, how it is associated with the operator and whether it is worth worrying about security. GSM-Networks in conjunction with Xiaomi software.

Technical essence of the function "Additional call"

Call Waiting allows you to receive a second call without interrupting an ongoing conversation. When you're on the line and a new call arrives, the smartphone emits a characteristic beep, at which point you have a choice: answer, ignore or reject a new call.

If you don't have time to answer or deliberately ignore the second call, the redirect mechanism goes into effect. The "Additional Call Redirected" status means that your phone sent a line occupancy signal to the network, and the operator redirected the caller to a preset number (usually a Voicemail service).

It is important to understand that this is not an Android system error or a MIUI firmware bug. This is a normal network behavior that simply appears on the device screen. Xiaomi smartphone correctly reads the status codes from the base station and informs the user about the fate of the missed call.

In some cases, users confuse this feature with a “Third Call” or a conference call, but redirection works differently: it does not unite participants, namely, it redirects the call stream to another address on the network.

💡

Use the redirect function if you don’t want to be called during important meetings – just set a “if busy” redirect to a silent number or answering machine.

Why is the notification appearing on Xiaomi?

The appearance of the corresponding notification on the Xiaomi screen depends on the settings of the smartphone itself and the parameters of the SIM card. By default in many tariff plans, the Voice Mail service is activated by the operator, and it is to it that the redirect is sent.

Notifications can be hung in a curtain or displayed briefly, depending on the version of the shell. In new versions of HyperOS, the logic of displaying system events has been changed, which can make the status more visible to the user.

The main reasons for the emergence of status:

• 📞 Line occupancy: You talk and a second call arrives, which is reset to the answering machine.
• 📵 Network Inaccessibility: If the phone is off or out of range, the call is also forwarded (Unavailable status»).
• ⏱ Expired waiting time: You don’t pick up the phone and the call goes to redirect after a certain timeout.

Often, users will only notice this message after the call is over, when they check the call log, and it can indicate that the call has been forwarded, which is useful information for understanding why the caller was unable to reach you.

Configure forwarding through the engineering menu

To manage these functions, you do not need to get into the jungle of operator settings. Xiaomi, like most Android smartphones, allows you to manage redirects through special devices. USSD-This gives you complete control over where your "additional calls" go».

To check the current status of all redirects, you can use a universal code. Open the Phone app and type *#002#. This code is a GSM standard and works on most SIM cards.

After you dial the code, you'll see a system window that shows the status of forwarding voice calls, data and faxes, and if you have voice call forwarding disabled, you'll see that the service is deactivated globally, and if it's on, you'll see the number that's being reset.

To disable all types of redirects (when busy, unavailable, unanswered), use the code ##002#. This action will instantly reset all routing settings on the operator side.

Management through the standard MIUI menu

If you prefer a graphical interface over codes, Xiaomi provides convenient settings in the call menu.The path to these may vary slightly depending on the version of MIUI, but the general logic remains.

Go to the Phone app, click three dots in the corner and select Settings. Next, look for Accounts or «SIM-If there are two cards, this menu will either have the option “Additional settings” or “Redirection».

Here you will see four main types of redirects:

• 📞 Always: All incoming immediately go to another room.
• ⏳ If busy: Activates when you speak on the phone (this creates the status of "Additional call forwarded»).
• ⌛ If no response: It works after a few horns.
• 🚫 If not available: When the phone is off or offline.

By clicking on each item, you can see the current redirect number or turn off the feature.Please note that changing these settings requires a network signal, so make sure the SIM card is active.

The influence of the operator on the status of the call

Remember that the redirect brain is not just your Xiaomi, but also the carrier’s equipment, and it is the MTS, Beeline, Megafon, or Tele2 servers that decide to redirect the call.

Sometimes the phone displays a forwarding status even though you didn't turn it on, which means that the service is activated by default at the plan level. Operators often turn on voicemail automatically when they issue a SIM card.

The table below shows the standard codes for status verification with the main operators (may change, are relevant for the Russian Federation):

Using ##002# is a one-stop solution that works on 99% of networks worldwide, regardless of the brand of the operator, and it is the fastest way to reset to factory settings.

💡

Universal code ##002# disables all types of forwarding on the operator side, ignoring the settings of the phone.

Problems with dual SIM (Dual SIM)

Xiaomi owners often use two SIM cards.This creates additional confusion.The status of "Additional Call Redirected" may refer to one of the SIM cards, while the user thinks the problem is global.

When one SIM card is busy talking, the second one may not be available to incoming ones unless the Call Forwarding on Busy feature for the first SIM is configured to the second number (although this is a rare scheme).

It is recommended to check the settings for each SIM card separately. Go to the call settings, select SIM 1, check the forwarding. Then switch to SIM 2 and repeat the procedure.

It is also worth noting that when using the “4G preferably” mode on some older Xiaomi models, the second SIM card may temporarily become unavailable during a conversation on the first one, which causes instant redirection of incoming to the second SIM.

💡

If you rarely use a second SIM card, it’s easier to temporarily disable it in the settings to avoid confusion with forwarding notifications.

⚠️ Attention: Redirecting to paid numbers or other carrier numbers can cost money. Make sure that the redirect box does not specify a paid service unless you want to bear the cost of incoming calls redirected to another number.

⚠️ Note: When you reset your network settings or reflash Xiaomi, your redirect settings may be reset to standard (operator) settings. Always check them after major system updates.
