You can try add pjproject as a component of your project, 
 you need write a cmake file to help build.

Newbie trying to use external library esp-idf-lib

Here is an useful project, you can start from it. pjlib for esp32 pjlib is a base module of pjproject, you need add other modules (other modules: pjlib-util, pjmedia, pjnath, pjsip .... )

if build all ok, you can start write your own sip client directly call pjsua/pjsip api.

Maybe more code need write in pjmedia module (Access media device use ESP32 platform api interface):

• audio capture/playback
• video capture/render

You also can write sip client not use pjsip library. (stun/turn support, you can ask below these github projects)

• ESP32-ADF official voip sample There is a video on youtube. video
• SIP client for ESP32 to initiate a phone call from a door bell
