Solved One Way Audio a couple of days after installing the app

[David Schumann]

Hello,
I am seeing strange behavior with the 3CX App on an android device.
When I install the app and configure the extension, it all seems to work fine. I can place calls without a problem and have no complaints about audio or anything really. After a day or two, there is no outgoing audio when on any call on this mobile device. The same extension configured on another device works fine. All other devices work too. We checked the security settings for the 3cx app. All seemed to be set correctly. Removing the configuration for the extension and reconfiguring it made no difference. Reinstalling the app works. After reinstallation, all problems are resolved. However, a couple of days later, the problem reappeared. Again, the only solution was to reinstall the app.
I presume this will happen again in a couple of days. Therefore, I wanted to ask if anyone else has had such issues and knows of a solution.

Any help would be much appreciated.

Also, I checked the Android version. The device is running android 9. Not the newest, but should still work for the 3CX app.

Hi @David Schumann,

Can you test by turning off the Car/Bluetooth Support (Telecom API) option from the Settings >> Advanced menu?

When you have this issue, can you try the following:

1. Dial *777, do you hear any audio coming back when you speak to the Echo Test?
2. If you dial an internal extension, do you also have no audio?

Thank you for the response. I will test this should it happen again.
Ill report back

I have found the cause of the problem. However, I haven't gotten the chance to test the Echo service and an internal extension yet.
This behavior occurs when the Bluetooth compatibility mode is activated. However, it only seems to happen with this phone, a Samsung S8.

When I have the phone in my hands, I will test the echo service.

Thanks again for your help.
Regards
David
