Hi Folks! At first let me say, that this project is great and the only help putting a sip framework onto headless systems. I was very happy having found it! While I am rather not experienced coding C in userspace applications I managed to adapt simple_pjsua to interact with a java daemon kind of remote controlling it. Now I need to add more gain to our microphone input, it is too silent out of the box. Since my alsa driver offers no "mic boost" button I investigated the pjsip API and discovered pjsua_conf_adjust_rx_level() should fullfill my needs. Even more because I can change this from application side while running. Is it sufficient simply to add "pjsua_conf_adjust_rx_level(0, 3);" into simple_pjsua.c after "/* Init pjsua */" to achieve this? Of course I am trying this out by myself now and I will see if sufficient or not, but whatever success I have or not, is there a more canonical way how this is done? I wan't to avoid "dirty hacks" when it is done right in another way!
