V18.0 Android App One Way Audio

[imCalebM]

• Phone Model: Samsung SM-A515F/DSN
• Android Version: Android 12
• App Version: 18.1.2.69
• 3CX PBX Version: 18.0 (Build 418) / Debian Hosted in Azure
• Network Connection: Wifi and/or LTE, IPv4
• Client is on a different network than the PBX which is hosted in Azure.

This phone doesn't seem to be sending any audio, i.e. caller cannot hear any audio but I can hear them fine. The issue is present on both Wifi and 4G/LTE.

I found some other forum posts mentioning the Telecom API and the Audio subsystem API so I have tried changing these settings to no avail.

I have uninstalled and re-installed the 3CX app as well as re-provisioning the account. I have also tried other extensions on this phone. After this I was beginning to suspect the phone's microphone was dodgy but other apps using the microphone and native calling all works fine.

The one-way audio seems to affect all calls from the 3cx app inbound or outbound, these are the scenarios I have tested:

• Internal call to another extension
• external call
• echo test *777
• *888

Fortunately I have multiple 3CX instances in Azure so have been able to test with extensions on another PBX and the issue is still there.

Thanks for your feedback.

Could you provide me in PM the app's verbose logs in order to understand what's going on and help you out with your issue?

1. Enable Verbose Logs: “Android App Settings (top left hamburger menu) > Settings > Advanced > Troubleshooting > Enable verbose logging”.
2. Reproduce the issue and “Send log report”: Android App Settings (top left hamburger menu) > Settings > Advanced > Troubleshooting > Send Log Report

Thanks
