Dear Apanas,
Thanks for your inquiry in Quectel forum.
Please check why it will return “+QAUDRD:0” which means that Module is not in recording when you check it. Whether there have check the call state, the caller and receiver can hear the voice normally ?
And if you want to stop recording, it is better to use the command AT+QAUDRD=0 to stop it. But i can not see such command in your test log. Please double check it. And the following test example just for your reference. Please confirm it. Thanks!

I don`t know why return “+QAUDRD:0”. And i force stop recording by ATH command accordingly note 6 in

During the call caller and receiver hear the voice normally.
Thanks.

Dear Apanas,
As far as i know you use EC25 module right ? But why you will refer to GSM Audio Player Application Note ?


Please check the following right document and refer to the example in it. Thanks!
