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
