Xiaomi and Redmi smartphone owners often face a situation where the caller hears short beeps and then resets, even though the caller has not yet had time to pick up the phone. This is standard network behavior, but it is not always convenient. Call duration is a parameter that determines how long the system will wait for a response before an automatic shutdown or redirect.
You can change this spacing directly from the device, but the process is not always obvious due to the features of the MIUI or HyperOS shell. In this article, we will discuss where the desired settings are hidden, how they affect incoming and outgoing calls, and why standard methods may not work in your region.
It’s worth noting that timeout management often depends not only on your phone, but also on your carrier’s settings, but adjusting the settings in your smartphone’s menu allows you to force the network to request a new timer value, which solves the problem of too short beeps in most cases.
Impact of the operator on waiting time for response
Before you go into the depths of settings, it's important to understand the mechanics of the process. Call Forwarding Timer is a network service. The operator sets a time limit for the phone to call, which usually ranges from 15 to 30 seconds.
If you change the settings on your phone, you are actually sending USSD-A command or a request through a menu that the operator is required to execute, but not all operators allow this parameter to be changed arbitrarily, some of them fix the time rigidly, for example, at 25 seconds, ignoring the user's attempts to set 60 seconds.
In addition, there are different redirect scenarios, each of which has its own timer:
- 📞 Busy: If the line is busy with another conversation.
- 📵 Unavailable: if the phone is off or out of range.
- ⏳ Unanswered: The main parameter we are trying to change.
- 🔄 Always: Immediate forwarding of all calls.
Understanding these differences is critical. If you set up a forwarding to voicemail, but the "no response" timer is minimal, the Caller ID may not even have time to show up on the screen before the call goes to the answering machine.
Configure through the standard menu "Phone"
The easiest and safest way to change the settings is to use the built-in dialer interface. In Xiaomi smartphones, the Phone app is responsible for this, which can be both stock from Google and proprietary development of MIUI.
To start, open the app and find the menu button. Depending on the firmware version, it could be a three-point in the corner or a settings button. We need a section that's linked to accounts or additional settings.
The sequence of actions is as follows:
- Launch the Phone app.
- Click on the settings icon (cog) or three dots.
- Select Call Settings or Additional Settings.
- Find the Redirect or Incoming Calls section.
Here, the system will try to download the current settings from the SIM card, which can take a few seconds to do, and if the menu loads, you'll see a list of forwarding options, and we're interested in the "If it doesn't respond" option.
☑️ Checking the redirection settings
Use of the USSD-timer-control
If the graphical interface does not give the desired result or looks stripped down, help come. USSD-These are direct commands that go to the operator's server, and they even work on push-button phones, and they don't require Internet.
The primary code for managing redirects is *#61#. When you type it and press the call button, you will see the information box, which will indicate the number to which the redirect is going, and most importantly, the delay time in seconds.
To change this time, a more complex command is used. The syntax looks like this.
**61*[redirect number]11[time]#Where [time] is the desired duration in seconds. The available values are usually multiples. 5: 5, 10, 15, 20, 25, 30. For example, to set the timer in 30 second 79990000000, team: **61*79990000000*11*30#.
⚠️ Note: Not all operators support arbitrary timer changes through USSD. If you receive an error message after entering the command, then this function is blocked on the provider side.
It's also worth remembering that when you use codes, you need to specify the voicemail number or another phone number where the call will be transferred, and if you just want to increase the time of the beeps without redirecting, this method may not work, since the network requires a routing endpoint.
Specifics of work in MIUI and HyperOS
Xiaomi’s shells are known for their aggressive optimization and unique menu structure. In recent versions of HyperOS, the path to customization may be different from classic Android.
Often users can't find the right item because they're looking for it in the general settings of the system. MIUI If you have a dual-sim phone, make sure you change the settings for the one that you want. SIM-maps that have problems.
In some regions (such as India or China’s firmware), functionality may be stripped or expanded with additional recording and anti-spam features that intercept call management, and in such cases, it is recommended to switch the region in the phone settings to Russia or Global to unlock standard GSM protocols.
What to do if the settings menu is empty?
Popular table USSD-code-setting
For convenience, we’ve put together basic commands to help you manage your call settings on Xiaomi devices, which are universal and work on most GSM networks.
| Action. | USSD-code | Description |
|---|---|---|
| Status check | *#61# | Shows the number and delay time for "Unavailable" |
| Change of timer | **61*[number]11[sec]# | Setting a new waiting time (5-30 seconds) |
| Disabling redirection | ##61# | Resets settings for "no response" calls |
| Total reset | ##002# | Cancels all types of voice/data/fax forwarding |
Use these codes carefully. Incorrectly entering the recipient number can lead to your calls going to an outsider or to a paid service.
⚠️ Note: Before changing settings, make sure you have a positive balance.Some carriers may charge you to activate forwarding services, even if the call itself is forwarded for free.
Solving challenges with challenge resetting
There are situations where the settings seem to be correct, but calls are still reset instantly, which can be a sign of a deeper problem: network login failure or coverage issues are often interpreted by the system as "phone busy" or "unavailable," which triggers redirects ahead of time.
Try the following steps to diagnose:
- 🔍 Check the network mode: switch manually from 5G/LTE on 3G/2G Settings menu → SIM-maps and mobile networks, sometimes in areas of unstable reception 5G The phone loses its signal for a split second and the call goes to forwarding.
- 🔄 Re-registration: Turn on and off flight mode, which will force the phone to re-register and update its service profile.
- 📱 Network reset: In extreme cases, you can reset mobile network settings. This will delete the saved points. APN Bluetooth settings, but often solves voice problems.
It’s also worth checking if you have any spam blocking software installed. Apps like GetContact or Xiaomi’s built-in antivirus can aggressively filter calls by resetting them if a number isn’t found in the database, creating the illusion of a short timer.
💡
If none of the methods helped to change the duration of the beeps, the problem is guaranteed on the side of the operator, and it can only be solved by contacting technical support.
