ESP32 Forum

I am currently working on a time-sensitive project using the ESP32-S3-Korvo-2 board, and I am trying to build the ESP-ADF VoIP example. However, I have encountered consistent build issues across multiple versions of ESP-IDF, including:

ESP-IDF v6.0

ESP-IDF v5.4.1

ESP-IDF v5.3.3

Despite following the official documentation and ensuring compatibility between ESP-IDF and ESP-ADF (including release v2.7), I am unable to successfully build the VoIP example. I have tried multiple environments and setups, but the build always fails with various errors.

This issue is blocking progress on my project, and I would greatly appreciate your support in one or more of the following ways:

Guidance on the correct ESP-IDF and ESP-ADF version combination for the VoIP example (particularly for ESP32-S3-Korvo-2).

Any patches, updated examples, or fixes to make the VoIP demo buildable.

Suggestions on alternative working examples for VoIP functionality using the ADF or ESP-IDF.

Clarification if the VoIP functionality is currently broken or deprecated in the latest releases.

I am happy to provide build logs, configuration details, or any other information required to help debug this issue.

This is quite urgent as we are approaching a project deadline. Your assistance will be immensely appreciated.

Best regards,
Ajaysinh.
