ESP32 Forum

Hello Everyone,

I recently bought ESP32-S3-Korvo-2 Board version 3.1, i have successfully built the code with ESP-IDF version 4.4.8 along with
ESP-ADF master brach of VoIP Example.

The VoIP Example can flash and run on the mentioned board. I can register it onto SIP Server. However, there is no audio both
incoming and outgoing.

On close observation of SIP Server Logs it is found that there is no common codec between two end points. I am sure the VoIP
SoftPhone which i am having has the CODEC ulaw and alaw. But, VoIP application has an issue with the CODEC.

Does anyone face the similar problem or does know how to enable the CODEC in ESP32-S3-Korvo-2 board ?

It would be great if someone help or suggest reagrding the same.

Best Regards,
Anand

Hello Ghanand:

I had exactly the same issue last week when I got my board.

In order to make it work I had to go back to ADF V2.6 instead of using Master. I'm using ESP-IDF V5.1.1. I didn't test with newer versions of IDF so probably anoter combination might work.

I'm using Asterisks in a Raspberry PI as PBX.

Kind regards,
Luis

Hi Luis,

Thank you so much for the details. I will try with ADF V2.6 and test it.

Thanks & Regards,
