Hi, PJSIP endpoint uses PCMU codec to receive audio from the remote endpoint. I then use the wav writer to record audio. When I play the recorded audio, the volume is very low. Should I amplify the audio before recording the audio into wav file? If yes, how do I do it? I have attached sample audio.
