方式1 ：如果是官方的板子可以用这个封装的很好，

https://github.com/espressif/esp-adf/blob/master/examples/protocols/voip/README_CN.md

内存消耗还行，可以加lvgl的界面

方式2：baresip 改造，自己试了下还有些bug 不过内存只剩5万多的字节了不优化很难在运行lvgl 。在esp32s3 450kb的内存:cmake 可以参考下面的

剩下的改造下i2s 、re/queue和、pthread参数即可运行效果:

方式3：用简单的改造还剩22万多字节可以运行lvgl界面

GitHub - GeorgeBregman/ESP32-SIP-Voice: ESP32-based SIP VoIP client (ESP-IDF + FreeRTOS). Tasks, queues, and core SIP call flow logic. Uses G.711 µ-law and I2S codec (e.g., ES8388).

提供的例子用于非注册的需要改动的很多 ken也很多，个人感觉这个比较好些
