modu.PBX Phone app — FAQ
How do I register the app?
modu.PBX Phone is for employees of companies using modu.PBX. Tap the SMS link sent by your company's administrator, or scan the QR code they give you in the app. Then enter the verification code sent to your phone, and you can use your office extension right away.
Calls don't ring when the app is closed.
Make sure notifications are allowed for modu.PBX Phone in your device settings. On Android, excluding the app from battery optimization and allowing full-screen notifications makes incoming calls more reliable.
The call connects but there is no audio.
Check that the microphone permission is allowed. If the problem happens on office or public Wi-Fi, try mobile data, and let us know at support@modupbx.com with details of your network.
I changed my phone.
Register the new phone the same way (SMS link or QR code). Your administrator can remove the old device in the portal.
Can I use the service abroad?
For security, the modu.PBX service accepts connections from within the Republic of Korea only. The app will not connect from other countries.
Are imported contacts stored on your servers?
No. Contacts imported from your phone are stored only on the device where the app is installed and are never sent to our servers.
Can I make emergency calls?
Please use your phone's built-in dialer for emergency calls. Depending on your internet connection, emergency calls may not connect through modu.PBX Phone.
