How to organize a conference call on a Xiaomi mobile phone

Xiaomi’s mobile devices have long since ceased to be just a means for voice calls, becoming powerful tools for business communication and personal communication. The functionality of a standard phone application in the shell of MIUI or HyperOS allows you to combine several interlocutors into one line, which is critical for promptly solving work issues without using third-party software. However, many users are still unaware of the hidden capabilities of their gadget or face difficulties when trying to create a group conversation.

Modern cellular and Internet protocol technologies offer a great opportunity for users of Redmi and Poco smartphones. You can easily switch between a regular call and a conference, add new members on the fly and manage access rights to the microphone. Understanding how this feature works will help you stay in touch with your team or family, using only built-in system capabilities.

In this article, we will take a look at all aspects of group calling, from basic settings to troubleshooting, how to use conferencing properly, what are the limitations of mobile operators, and how to optimize sound quality during important conversations.

Principles of working group calls in MIUI

Multiple call organization on Xiaomi smartphones is based on VoLTE (Voice over LTE) or classic GSM/3G standards, depending on your operator’s settings. The standard Phone app, which is pre-installed on the brand’s devices by default, has a built-in call merging algorithm. This means that technically you create multiple separate connections that your smartphone and the operator’s network combine into a single audio session.

It is important to understand that the quality of communication and the number of subscribers connected directly depend on the tariff plan and the technical capabilities of the cell tower. Some operators allow you to combine up to 5 people in one group, others limit the number of participants to three.

The MIUI Call Management interface is designed to minimize user activity, the main control buttons are on the screen during a conversation, allowing you to quickly respond to changes in the conversation dynamics, and automatically tracks the status of each participant and informs you about joining or leaving the conference.

⚠️ Warning: Make sure you have enough funds on your balance sheet as each line added is charged as a separate minute of talk according to your plan.

Step-by-step instructions: Creating a conference

The process of creating a group call on Xiaomi devices looks logical and consistent, although it requires several actions in strict order. First, you need to initiate the call of the first subscriber from your phone book or dial the number manually. Wait for the connection and make sure that the interlocutor hears you well before moving to the next step.

Once you've made contact with the first person, you'll have an additional control panel on the screen, and that's where the key button for adding the second person is located, and you'll click on it, and you'll put the first hold call, and you'll be able to dial the second number, and this mechanism allows you to personally control who you're connecting to the conversation.

When the second person responds, the display display displays information about the two active lines. To complete the procedure, press the Combine or Merger button. After that, all the people in the same audio environment can hear each other. If you want to add a third person, the procedure is repeated in the same way.

• 📞 Call the first participant of the conference and wait for the answer.
• ➕ Click the Add Call button on the control screen.
• 🔢 Enter the third party number or select from the contacts.
• 🔗 Press the “Unite” button so that all the interlocutors hear each other.

Managing participants and tuning the sound

When the conference is already active, you have to manage the participants effectively. The call screen on Xiaomi smartphones allows you to see the list of all connected subscribers and their status in real time. You can individually turn off the microphone of a particular person if there is an outside noise in the line, or temporarily turn off the sound on your device to talk to people nearby.

Special attention should be paid to the sound settings, because in conference mode, the speaker of the phone works with increased load. It is recommended to use a headset or put the smartphone into hands-free mode, putting it on a stable surface, this will ensure a uniform distribution of sound and allow you to hear all participants without distortion.

Some versions of HyperOS firmware have voice prioritization, so if one participant is too quiet, the system can automatically amplify the signal, but you don't need to rely on automation, you should ask everyone to speak clearly and in turn.

💡

Use a wired headset for conferencing: this will reduce audio latency and eliminate battery drain during lengthy negotiations.

If you need to discuss details with one of the participants in private, without interrupting the general conference, use the private conversation function. Choose the right subscriber in the list and press the isolation button or (private), at which point the rest of the participants will hear waiting music or silence while you solve the question.

Using Internet Protocols for Communication

Apart from the classic cellular service, Xiaomi phone owners can organize a conference over the Internet using VoIP technologies. Apps built into the ecosystem or installed additionally (for example, Google Meet, Zoom or Telegram) often provide broader capabilities, such as video calls and screen demonstration. However, the built-in Mi Talk messenger (where available) or the standard Google feature set allows you to do this natively.

The main advantage of Internet calls is that there is no per-minute charging if you are in Wi-Fi coverage. This is especially true for international conferences, where the cost of a minute of cellular communication can be prohibitively high.

To set up high-quality Wi-Fi connectivity on Xiaomi’s device, it’s recommended to go to network settings and make sure that 5GHz is used, which is less busy, and it’s also worth turning off power saving for the application through which the call is being made so that the system does not interrupt the background optimization process.

⚠️ Note: When using video conferencing via mobile Internet, make sure you have an unlimited tariff or a large packet of traffic connected, otherwise the bill for communication may be unpleasantly surprising.

Typical problems and ways to solve them

Despite the system’s fine-tuning, users sometimes face technical difficulties when arranging group calls on Xiaomi, the most common problem being the inability to combine calls, which may be because your carrier does not support conferencing at your current rate or in your region.

Another common cause of failure is software configuration conflicts, for example, if the Call Record feature is enabled, the system may block the addition of a third party because it cannot record multiple lines at the same time or mix them correctly, in which case try to turn off the recording before the conference begins.

If the sound in the conference is intermittent or echoes are heard, try switching network type.Switching from Preferably 5G to 4G LTE often stabilizes the connection, as fifth-generation coverage can still be unstable in some buildings.Seeing the cache of the Phone application through system settings can eliminate software glitches.

• 📉 Check the signal level: at least the conference 2-3 division.
• 🔄 Reboot your smartphone: it will reset temporary network errors.
• 🚫 Turn it off. VPN: virtual_private_Networks may conflict with VoLTE.
• 🔊 Turn down the volume: at maximum volume, the speaker can be distorted.
