Ashwin, I'm using the unmodified pjsua_app.c reference application that is included with version 1.12 and located in the distro at: <pjproject-1.12>/pjsip-apps/src/pjsua/pjsua_app.c I see in the reference application on line 4662 where callbacks are initialized as: pjsua_app.c ------------------- /* Initialize application callbacks */ app_config.cfg.cb.on_call_state = &on_call_state; app_config.cfg.cb.on_call_media_state = &on_call_media_state; app_config.cfg.cb.on_incoming_call = &on_incoming_call; app_config.cfg.cb.on_call_tsx_state = &on_call_tsx_state; <more initialization follows> However I see nothing that initializes callbacks for catching 5xx SIP responses. So this is when I started digging into the pjsip User Agent Library and found the pjsip_inv_callback structure which defines on_state_changed - and that seems to me like it would do the trick. I just don't see how to get that callback wired in to the higher-level pjsua reference application (which leads me to believe that I'm missing something trivial). You mentioned that there are many ways to get notified of 5xx SIP responses, so how could the pjsua_app.c reference application be modified to catch such responses?
