VOIP Example no Audio through ESP after call answer

Postby Captainavi » Thu Feb 27, 2020 6:08 pm

Hi,
I have an ESP32 set up with MAX9860 audio codec. A Yate server is running on a local IP that I am using to register the ESP to. I have a softphone Android app that I am using to call the ESP. The softphone app is able to call other softphones on the network and play audio through fine. I am running the most recent VOIP example from ESP-ADF with an output sampling rate of 48Khz. The ESP registers on the network properly as far as I can tell. It will answer calls from the network but no audio plays through once it picks up. It starts the audio codec when the call picks up and plays low frequency noise from the speaker. The noise does not change or react at all to audio from the phone.

Does anyone know what these errors mean or what I am doing wrong? The codec is working fine with the other demos so I do not think that it is the problem.

Any thoughts are appreciated.
