Is it possible to record Voip calls in Android? I tried using the below options for MediaRecorder.AudioSource
VOICE_DOWNLINK
VOICE_UPLINK
VOICE_CALL[ UPLINK + DOWNLINK]
VOICE_COMMUNICATION
Case 1: If I start recording before making the Voip call, then the recipient is not able to hear my voice. Also after recording I can hear only my voice. This suggests that the microphone is blocked by my app.
Case 2: If I try to record during Voip session then I get E/MediaRecorder﹕ start failed: -38 error.
I don't have any problem recording phone calls. Another thing which I observed is in Kitkat the error doesn't occur during Voip session and recording is successful but I am unable to hear recipient voice. The problem arises in Lollipop. I haven't tested on prior Kitkat versions.

VoIP calls cannot be recorded in android as the microphone will be in use as you have gathered in your testing. For normal Phone calls microphone is not in use. – Srihari Karanth Jan 11 '19 at 07:02
