Not all phones support call recording. Remove any other call recording
apps, disable noise cancellation features of your phone,reboot your
phone and re-install ACR, set recording delay to 5 seconds and try
again. Also please try all recording formats.
If nothing works, set Audio Source to MIC in ACR settings and use call
recording with speaker
