The main advantage for Redmi owners, POCO flagship Mi/Xiaomi — It's possible to call even when there's a weak signal on the cellular network, if you have access to Wi-Fi or mobile Internet, for example, in basements, country houses or when traveling abroad, where roaming costs a lot.

What Xiaomi smartphones support SIP-call-up
Theoretically, any Xiaomi smartphone based on Android 8.0+ can work with SIP, But in practice there are limitations:
- 📵 Without root rights, you can’t use the built-in SIP-client MIUI (It is hidden in the firmware, but is disabled by default).
- 🔄 On older models (before the Redmi Note 8) there may be problems with the Opus codec - the voice will be interrupted.
- 📶 For stable operation, you need Wi-Fi 5 (802.11ac) or 4G/5G ping < 100 miss.
We tested it. SIP on the following devices (results in the table):
| Model | Support for SIP | Best app | Notes |
|---|---|---|---|
| Xiaomi 13 Pro | ✅ Yes. | Zoiper or Linphone | Works without lag on MIUI 14 |
| Redmi Note 12 | ✅ Yes. | Groundwire | Requires to disable battery optimization for SIP-applications |
| POCO X5 | ✅ Yes. | Bria Mobile | Best sound quality among public sector employees |
| Redmi 10A | ⚠️ Partially. | CsipSimple | Sometimes stops calls when switching between Wi-Fi and 4G |
Important: on smartphones with a Snapdragon processor 4xx (Like Redmi. 9A) SIP It can consume up to 15 percent of the battery per hour because of poor core optimization. POCO M5 or newer.
⚠️ Attention: On devices with MIUI Globally, some SIP-applications (e.g., applications, 3CX) To avoid this, install the app from APKMirror, not from Google Play.
How to choose SIP-Provider: Comparison of tariffs and coverage
The provider depends on the quality of communication, the cost of minutes and available numbers. We selected 5 proven services that work with Xiaomi without additional settings:
- 🏢 Mango Office is the best choice for business (virtual PBX, recording conversations). Start rate - 300₽/russia.
- 🌍 Sipnet – suitable for international calls (calling in the US – 1.5)₽/Min: no mobile application.
- 📞 Zadarma gives you a 3-month free number, perfect for tests, but the quality of the connection depends on the time of day.
- 💼 Telfin - Integration with CRM (for example, Bitrix24). The Profi fare is 500.₽/call analytics.
- 🔗 VoIP.ms – for advanced users (routing settings, IVR). You only pay for outgoings (0.5)₽/mine).
If you need a Moscow number, look for Mango Office or Telfin – they provide numbers with a code. +7 (495) at no additional charge for calls to Ukraine, Kazakhstan or Belarus is more profitable than Sipnet (tariff "International").
Before paying, check:
- Does the provider have a mobile app (simplifies setting up)
- Does he support SRTP (encryption).
- What codecs are available (optimally: Opus, G.729, G.722).
⚠️ Note: Some providers (e.g. Zadarma) block dynamic registrations IP-If you have mobile Internet, use Cloudflare. WARP stable-connection.

How to check if the built-in work SIP?
Solving the Problems: Why SIP It doesn't work for Xiaomi.
If after setting up the calls do not pass or the application gives errors, check these points:
| Mistake. | Reason. | Decision |
|---|---|---|
| 403 Forbidden | Incorrect login/password or IP blocked | Check the data in the personal account of the provider. If the lock is, write in support. |
| 408 Request Timeout | The server of the provider is not responding | Try another server (for example, sip2.provider.ru instead of sip.provider.ru). |
| No incoming calls. | Push notifications disabled | In Android Settings: Apps → Zoiper → Notifications → Permission. |
| Sound cliffs | Problems with codec or network | In Zoiper, select a codec. G.711 If it doesn't work, connect to another Wi-Fi network. |
If the problem persists, try:
- 🔄 Change the app (for example, from Zoiper to Linphone).

If SIP It does not register on the mobile Internet, but it works through Wi-Fi, the problem is that the ports are blocked by your operator (MTS, Beeline, Tele2). TLS instead UDP or connect through VPN.
How to call through SIP from a computer and sync with Xiaomi
If you need to take calls on both a smartphone and a PC, set up multi-registration - simultaneous connection of one SIP-I'm using multiple devices for this:
- Install Zoiper or MicroSIP on your computer (Windows/macOS/Linux).
- Enter the same account details as you did on Xiaomi.
- In the provider settings (personal account), enable the option Multi-registration or Additional devices.
Now incoming calls will be calling both devices to avoid echoes:
- 🎧 Use headphones on a PC or smartphone.
- 🔇 In Zoiper settings, turn off acoustic echo suppression (sometimes it works worse than the built-in one). MIUI).
To sync your call history between devices, connect Google Contacts or use CRM-system, for example, Bitrix24 telephony-module).
