It is not possible to be on Audio Call and regular phone call at the same time as the built-in microphone on device can only be used for one function at a time. If a regular phone call is answered during Audio Call, Audio Call will terminate automatically.

The quality of your call may be affected when the network connection (eg. Mobile Data connection, Wi-Fi connection, Bluetooth connection, etc) is weak or when you are moving.  When the network connectivity is poor, the call may also drop.

To address issues with your Audio Call, you may also try the following:

Move to a location to that provides your device a stronger network signal for the respective network connection that you are using (eg. Mobile data connection, Wi-Fi connection, Bluetooth connection, etc)

Check that your Network Router Firewall settings are not blocking connections for Audio Voice Calls.

Close any applications that could be affecting your call. These include battery saving apps, open web browsers, video streaming, audio streaming, file sharing apps; which are using up network bandwidth and device memory. Older devices and older operating systems may not optimize bandwidth across apps and device memory as efficiently as the newer devices and newer operating systems.

Update to the latest version. We are always working to improve on the Audio Call quality, both you and the person that you are connecting with, should be using the latest version. The latest version can be found on the Apple Store and on the Google Play Store.
