3CX app for Android calling iOS bad quality

[jamesnb]

Hi everyone,
So I managed to get an Android phone, running Android 8.0 (I know, latest is 10). I installed the 3CX app on it, provisioning and all good to go.
The codecs I setup in the system as well as the extension are G711.U/G711.A - G729 - G722 / GSM-FR
From iOS to iOS: ok quality, listening/speaking both sides can hear
From Android to iOS and vice-versa: too much distort up to the point one cannot be heared and the other cannot hear anything. So both sides cannot communicate. The sounds seems "breaking". Strange things is that, although the devices are in the same WIFI network, the signal displaying a "red-orange" bar on the Android and the call finally dropped or went silent...
Any trick on the Android app to make it goes better?
Thank you very much
