internal calls not ringing

[Nathan.Chabloz]

One of my clients has the following problem:

When he receives an internal call, his phone doesn't ring. It only vibrates at the beginning and end of the call. External calls work perfectly.

He has an OPPO Find X5 Pro, the latest version of 3cx and its operating system. All vibration and ringtone settings are enabled, battery optimization mode is disabled, and he isn't in do not disturb mode or anything else.

We have already tried to re-provision his application.

Do you have any idea to solve the problem ?

Hi,

Did you try to remove and add the app again?

No i only tried to log out and then log in.

After removing et adding the app again, there is still the same problem.

Could you provision the extension on another phone and see if it's the phone or the config causing the problem?

Here are the things I tested:

- Logging into the account on another phone: Works fine.
- Uninstalling the app, restarting the phone, and reinstalling it: Still the same problem.

After talking with the customer, the ringtone works fine, but it's the vibrate mode that isn't working properly. This happened about three weeks ago, but it didn't happen directly after the OS update.
I tried calling from the central administrator, and the vibrate mode worked fine.

This seems to be a very specific issue with that phone. Other than suggesting trying out the beta app, not much else that can be traced/done.
