Changing the standard greeting to a personalized recording is not just a matter of aesthetics, but an important image element for the owner of the Xiaomi smartphone. When a subscriber hears your own voice, it immediately creates a sense of personalized approach and professionalism, especially if the number is used for business. Unfortunately, standard Android settings often hide the ability to quickly replace an audio file through the usual menu, forcing users to look for workarounds.
Mi and Redmi device owners are faced with the fact that MIUI or HyperOS interfaces do not offer an obvious “Download your file” button in the phone’s basic application. However, the technical possibility for this exists and is implemented through system codes or hidden engineering menus. Understanding the architecture of voice mail will allow you to bypass the standard firmware constraints.
Before you start manipulating, you need to understand that the answering machine is not a local function of the phone, but a service of a telecom operator that is remotely controlled, which is why the record is stored not in the memory of your device, but on the server of the cellular company. However, modern smartphones allow you to send a command to a server using a locally recorded audio file, if you correctly activate the corresponding data protocol.
The principle of voice mail in Android
To successfully replace a standard message, it is important to understand the mechanics of the process. Voicemail in Xiaomi smartphones, as in other Android devices, works on the principle of redirecting a call. When you are not picking up the phone or busy, the network redirects the call to a special number of the voice server, which is the server that plays the greeting and records the response of the subscriber.
The standard procedure for replacing a message usually involves calling your voicemail number, listening to robot instructions, and recording a new message through a microphone in real time. However, this method has a significant drawback: recording quality often suffers from compression of the audio codec by voice communication, and background noise can spoil the impression. Using a pre-prepared high-quality audio file avoids these problems.
System system MIUI It uses a standard protocol. VMWI (Visual Voice Mail Waiting Indicator to indicate new messages, but managing the greeting content itself often requires the use of special messages. DTMF-signal USSD-The commands that the phone sends when it connects to the server, and understanding this difference is critical to choosing the right method of setting up.
⚠️ Note: Before making changes to your forwarding settings or system codes, make sure that Voicemail is activated on your carrier plan. Without an active service from the provider, any settings on your phone will not work.
Preparation of a high-quality audio file
The quality of the final result depends on the source material. To record your own greeting on Xiaomi, it is best to use an external voice recorder or a professional audio recording application installed from Google Play. A standard voice recorder built into the MIUI shell will also work if you set it to the maximum recording quality.
The optimal format for a voice message is MP3 or WAV with a bitrate of at least 128 kbit/s. Higher values can be redundant, since the telephone network will still cut frequencies above 3.4 kHz, and too low quality will make your voice illegible and metallic. The duration of the message also plays a role: most operators limit the greeting time to 30-60 seconds.
When writing text, try to speak clearly, calmly and at a moderate speed. Avoid sudden volume drops and background noises. The finished file is stored in the phone's memory, preferably in the root folder or a specially created directory of Recordings, so that it is easy to find when sending.
- 🎙️ Write down the text of the greeting in a quiet room without echoes and extraneous sounds.
- 📁 Save the file in format MP3 or WAV for maximum compatibility with processing systems.
- ⏱️ Check the recording time – it should not exceed your operator’s limits (usually 30-60 seconds).
- 🔊 Listen to the recording through regular speakers to make sure the speech is legible.
💡
Use sound-normalizing apps to level the volume of the recording, which will help to avoid situations where the beginning of the message is barely audible and the end is "screaming."
Replacement method through engineering menus and codes
The most common way to change a greeting without calling the server is to use special system codes. There are a set of commands in the MIUI shell that allow accessing voicemail settings. First, you need to open the Phone application and go to dial mode.
Enter the ##002# code to reset all redirects if they were previously configured with errors, and then the voicemail activation code. The standard code for setting a greeting is often operator-dependent sequence, but the universal method for Android is to use the code **61*[voice mail number]#. However, it often requires a more complex algorithm to download your file.
Some versions of MIUI allow you to send an audio file as an MMS attachment to a service voicemail number, after which the system automatically recognizes it as a new greeting. To do this, open the file in the Explorer, select Share, and send via MMS to your operator number specified in the voicemail settings.
##4636##Entering this code in the dialer opens the hidden test menu. Go to Phone Information. You can find advanced redirect settings here. Find Call Forwarding and check for forwarding status when busy or unavailable. Make sure the forwarding number matches your carrier's voice server number.
☑️ Check before changing the settings
Configure through the system application "Voice mail"
In new versions of HyperOS and new MIUI builds, Google is rolling out the native Google Phone app, which has a built-in visual voicemail feature. If your Xiaomi has this app installed (rather than the standard MIUI Dialer), the process is simplified. Open the app, go to settings (three dots or gears) and select Voicemail.
In the settings menu, find "Hello" or "Greeting." The system will tell you to choose between a standard greeting (name of subscriber) and a custom one. Click on "User greeting" and follow the instructions. Unlike the old method, there can be a button "Download file" or "Select from memory" that allows you to immediately use the prepared audio file.
If there is no direct file download, the application will suggest recording the message through a microphone, in which case, play your prepared file on another device (tablet, computer) and hold it to the microphone of the phone while recording, which will preserve the high quality of the original recording, bypassing the limitations of the built-in voice recorder.
| Parameter | Standard greeting. | User recording | File download |
|---|---|---|---|
| Sound quality | Low (synthesis) | Medium (microphone) | High (original) |
| Duration | Fixed | Time-limited. | Limited in size |
| Difficulty | Automatically. | Requires a record. | Requires preparation |
| Uniqueness | Absent. | Tall. | Maximum |
Use of third-party applications for management
If Xiaomi’s regular tools do not allow you to download a file directly, specialized applications from the Play Market store come to the rescue. Programs like Visual Voicemail or solutions from specific carriers (for example, My MTS, My Beeline) often have advanced voicemail management functionality.
Install your carrier's app, log in, and find Voicemail. Most modern client apps have a My Greeting feature that allows you to either record a voice or, in rare cases, download a finished file from the device's memory. The interface of such programs is usually more friendly than the hidden Android menus.
There are also universal autoresponder applications that run on top of standard telephony, which intercept incoming calls if you haven't answered them, and play back the file you've chosen, but they require constant background work and appropriate Android resolutions, which can affect power consumption.
⚠️ Note: When installing third-party voicemail apps, carefully read the list of permissions requested. SMS applications with dubious reputations to avoid leakage of personal data.
Solving Typical Problems and Errors
Often, users are faced with a situation where after all the manipulations, subscribers still hear a standard message, this can be due to caching of data on the operator's side. After changing the settings on the Xiaomi phone, you need to wait 5 to 15 minutes for the servers to update the information.
Another common problem is the wrong audio file format: If the system does not accept the file, try converting it to a simpler format, such as a mono MP3 with a sampling rate of 44.1 kHz. Complex codecs or stereo sound may not be supported by the telephone network.
If you use two of them SIM-maps, make sure that the settings apply to the card that the voicemail is configured to. MIUI forwarding and voicemail settings for each SIM card can be stored in different profiles, and changing the settings for each SIM card SIM 1 won't touch SIM 2.

The subtleties of working in HyperOS mode
With the release of the HyperOS operating system in Xiaomi smartphones, the structure of some system applications has changed. The call settings menu could be moved. Now the path to settings often looks like Settings → Apps → App settings → Phone → Voicemail.
The new system also tightens the control of the background activity of applications. If you use a third-party answering machine, be sure to add it to the battery exception list (“No restrictions”), otherwise the system will force the process to close, and the answering machine will not work at the right time.
Owners of Xiaomi’s latest flagships should pay attention to the artificial intelligence features in calls. In some regions, the “AI Call Assistant” feature is available, which can answer calls by text or voice itself, in which case setting up a classic answering machine may not be relevant, since the smart assistant will intercept the call sooner.
💡
The main secret to success in HyperOS is to properly configure permissions and power saving exceptions for applications that handle phone calls.
