I compiled and ran the voiceCallApp program available in the Legato 76xx package. I built the app with mysys -t wp76xx voiceCallApp.sdef and uploaded the voiceCallApp.wp76xx.update app onto the Mango Red board. I could run the program successfully and make a voice call. The other party is able to hear my voice clearly but I was not hear back what they are speaking. I am using the MAIRDI headset with the mango red board. The have attached the logs.[VoiceCallApp\_20201103\_130153.rtf](https://mangoh.discourse.group/uploads/short-url/xKR3ToqgyCBuHWFb9bOcySnRhdp.rtf) (52.7 KB)

I don’t see problem to hear voice on mangoh board when voice call.  
How about using at!avaudio to check if you can do audio playback first?
