For my project I’d like to implement an auth mechanism for authorizing incoming calls/SIP messages.\ I found some building blocks for implementing digest auth via\ `pjsip_auth_srv_init `/` pjsip_auth_srv_challenge` /` pjsip_auth_srv_verify`\ and corresponding methods - which looks like it needs quite some code to get it working. Is there any implementation or example available using those framework methods?\ For now I only found it used inside the Asterisk framework.\ Especially interesting would be some PjSua / higher level API.\ \ Thanks and best regards,\ Flix
