3CX Mobile Android App - Echoes for caller

[Wesley v.d. Berg]

Anyone else experiencing issues with the Android app? E.g. callers can hear themselves like an echo when I call them, or they call me. I cannot hear any echo.

Have tried unchecking/checking echo cancellation, etc. in the Advanced Options, as well as the microphone gain. Have tried reinstalling app, clearing cache etc. Nothing works. This is happening over Wi-Fi and on speaker/handset. App is up to date. This started with the new android update.

Hi!

Could you try experimenting with the option in your App under Settings --> Advanced --> Audio Subsystem API?
There are 2 options there, after switching, try killing the app and re-launching.

Also some extra useful info:

• What version of the App do you currently have installed? (Menu --> About)
• Does this happen only when you are talking to External Callers, or also with other extensions?
• Do you have the Mobile App on speakerphone when this happens or do you have any Bluetooth headsets paired at the time?

Goodday Nick,

I Tried both options without succes.
The version is: 16.7.8.121
This happens with External and Internal calls
This happens when the phone is at speaker. It also happens when the phone is connected with Bluetooth.

Thanks!

This happens when the phone is at speaker. It also happens when the phone is connected with Bluetooth.

Does it happen also when you are not talking on speaker and not talking via a BT device?

So just talkting through the app? Yes this also happens on normal volume.

Hi @Wesley v.d. Berg,

Can you create 2 new extension, and PM me the attached config file for both and also a screenshot including the QR and login details for each so that we can log in from this side and test a call between the two extensions (upload them to a site that can share the file for me to download)?

I'm sure you probably already fixed this but I just wanted to chime in and share what fixed this for me in case anyone else comes here looking for a possible solution.
Turning off Car/Bluetooth support (Telecom API) fixed this for me. (Settings > Advanced under Audio options.)

The user I was helping has a Samsung Galaxy S7 on Android 8.0.
We are on 3cx version 16, cloud hosted.
Callers were hearing their voices echoing and her audio was very low.

@steszb

Thank you very much for sharing your solution!

Could you perhaps also provide us with the exact model id this as seen in the device's "Settings >> About Phone/device" section.
