How to dial an extra number on a Xiaomi smartphone: 5 working ways

You try to call the customer service, the company’s office or the medical facility, but after connecting to the main number, you hear the voice of the answering machine: “Dial an additional number...” On Xiaomi smartphones (including Redmi and POCO), this procedure is not always intuitive – especially if you are used to old button phones, where the additional was entered automatically. In this article, we will analyze all the current methods of dialing, including hidden MIUI chips, and also explain why sometimes the system “does not see” your extra one.

Complicating the problem is that different versions of the firmware (MIUI 12, 13 or 14) may have different interfaces for the call, and some operators (such as MTS or Beeline) handle the extra numbers in their own way, which leads to failures. We have tested all methods on Xiaomi 13 Pro, Redmi Note 12 and POCO X5 models — and are ready to provide clear instructions with nuanced information.

Method 1: Standard dialing through a Xiaomi call

The most obvious method is to use the built-in Phone app, but there are pitfalls: if you just dial the main number and then manually add the extra one, the system can interrupt the dial or send it as if it were a phone. DTMF-You can use a latency signal. To avoid this, follow the algorithm:

1. Open the phone application (icon with a handset).
2. Dial the main subscriber number (for example, +7 495 123-45-67).
3. Don't press the call button. Instead, tap three dots (⋮) in the upper right corner and select Add pause.
4. Enter an additional number (e.g. 105). A symbol will automatically appear between the main number and the additional number; this is the pause.
5. Now, click on the green phone to call, and when you connect, the system will wait for the voice of the answering machine to dial the extra one.

⚠️ Note: If after the symbol; the additional number is not dialed, check the settings DTMF (Also, some operators (e.g. Tele2) block automatic dialing - in this case, use the manual method.

Make sure the number is entered in an international format (+7 or 8)

Check the presence of the symbol; between the main number and the additional

Method 2: Manual input of the supplementary after the connection

If the automatic dialing doesn't work, you can manually type the dialing option after the subscriber responds, which is universal, but requires a speed of reaction:

1. Call the main number and wait for the connection.
2. As soon as you hear the request to dial an additional, click on the keyboard in the call interface (it will appear automatically).
3. Enter the numbers of the extra number. These will be transmitted as tone signals (DTMF).
4. If the keyboard does not appear, tap the screen during the call - it should surface.

🔹 Problem: On some models (for example, Xiaomi Mi 11 Lite), the keyboard may not appear due to a bug in the device. MIUI 13.0.4 Solution - Update firmware or use a third-party call.

Method 3: Configure DTMF to correctly transfer the additional

If the extra number is not automatically or manually passed, the problem may lie in the DTMF (Dual-tone multi-frequency) settings. In MIUI, these parameters are hidden deep, but they can be changed:

1. Open Settings → Applications → Application Management.
2. Find your phone in the list and tap it.
3. Select Permissions → Additional → Call settings.
4. Activate the Tone Set option (if it is disabled).
5. In the Tone Length section, set the Long value (this will increase the chances that the subscriber's PBX will recognize the signal).

⚠️ Note: On some firmware (for example, MIUI 12.5 Enhanced) the call settings may not be available. In this case, use the engineering menu.

Method 4: Engineering menu for advanced users

If standard settings don't work, you can go to the Engineering Mode, which is a hidden section where you can manually configure communication settings, including DTMF. Careful: improper changes can disrupt the network!

Instructions:

1. Open the phone app and dial the combination: ##4636##
2. In the menu that opens, select Phone Information.
3. Scroll down to the DTMF Settings block.
4. Set: Tone type → Normal tone duration → 200 ms pause between tones → 50 ms

Save the settings and restart the phone.

🔹 Note: In some models (e.g, POCO F4) The engineering menu can be blocked. In this case, use the app. MTK Engineering Mode from Google Play (MediaTek-based devices only).

💡

If the engineering menu doesn't open, try entering code through the Secret Codes app (available on Google Play), which supports alternative ways to access hidden settings.

Method 5: Third-party applications for a set of additional

If the built-in Xiaomi call stubbornly ignores your attempts to dial an extra, third-party apps will come to the rescue, offering flexible pause and DTMF settings, and also support saving numbers with additional contacts.

Top.-3 supplementary:

• 📞 Truecaller - automatically recognizes corporate numbers and suggests you enter an additional number. Supports pauses (;) and waiting (,).
• 📱 ExDialer – has a separate field for the additional number and a configurable duration DTMF.
• 🔢 DTMF Dialer – a specialized application for tone dialing, useful for old PBX.

🔹 How to save a number with additional contacts:

1. Open the Truecaller or ExDialer app.
2. Make a new contact.
3. In the number field enter: +74951234567;105 (where 105 is additional).
4. Now, when you call, you'll be dialing the extra automatically.

💡

The side of the call (like Truecaller) often handles extra numbers better than the standard Xiaomi app, thanks to flexible DTMF settings and pause support.

Manually editing the number before the call (for experienced users)

If you often have to call numbers with additional ones, you can pre-prepared a template in Notepad or Google Keep, and then copy it to the call. This will save time and eliminate errors in typing.

Examples of proper formatting:

• 📋 For automatic pause: 88001234567;105 (symbol; - pause 2 seconds).
• 📋 For manual input: 88001234567, 105 (comato, short pause).
• 📋 For the old PBX: 88001234567p105 (p is a forced pause).

⚠️ Note: Some operators (e.g. Rostelecom) block symbols; and, in this case, use only manual input after connection.

🔹 Lifehack: If you often call the same add-on, create a shortcut on the home screen:

1. Keep your finger in the free space of the screen → Widgets → Shortcuts.
2. Select Contacts and find the number with the additional number saved.
3. Now, drag the label on the screen.

Frequent Mistakes and How to Avoid Them

Even experienced Xiaomi users sometimes have problems with the additions, and here are the most common mistakes and solutions:

• 🚫 The pause symbol doesn't work: Make sure you use; (communal point) not, (communal). MIUI the comma is treated as a short pause, which may not be enough for the connection.
• 🚫 Addition fails: Check if the tone set is enabled in the settings (see section 3). If the problem persists, try dialing from another phone - it may be the fault of the operator.
• 🚫 Keyboard doesn't appear during the call: It's a bug MIUI 13.The solution is to update the firmware or use a swipe gesture up from the bottom edge of the screen during the call.
• 🚫 Subscriber does not hear tone signals: In the engineering menu, increase the tone duration to 300 ms and reduce the pause between tones to 30 ms.

Critical information: Some corporate PBXs (e.g. banks or government agencies) only use landline numbers, and if you've exhausted all of them, try Skype or Zoom, which emulates landline.
