Background Noise

[andypzx]

I am trialling 3CX hosted on Amazon Lightsail. Everything is going well apart from the background noises. When I am using the web client there are no issues.

If someone calls me internally or externally and I answer with the 3CX Client for Windows 16.0.1.81 or Android client then there is significant background noise (hear attached). However the background noise can only be heard one side. For example - if someone calls me externally and I answer on the Windows Client the noise is heard on the callers side and I hear nothing on the windows client - even when I mute my microphone the caller still hears the noise. When I call internally from the windows client to another windows client, the person I am calling, can hear the same background noise but I can't.

Any help with this would be appreciated as I would like to also use the window and android clients.

Problem is just on Android and windows client ? deskphones are not affected at all?

I'm not using any deskphones at the moment. Yes just the Android and Windows client.
The web client works fine, no noise.

Check audio codecs used on your trunk, should be the same your sip provider needs, in extensions check codec order too, should be the same as sip provider in first choice.

Does the Activity log show that Transcoding it happening?
