Ah yes, good point about AfxDaoTerm(), I missed that.

In this case, the only clean solution probably is to disable pjsua's 
SIP worker thread altogether (pjsua_config.thread_cnt=0), and create 
your own worker thread(s). Worker thread implementation should be 
very simple; it just needs to call pjsua_handle_events() 
periodically (see worker_thread() in pjsua_core.c). This worker 
thread should be created after pjsua_start(), and it should be 
stopped before calling pjsua_destroy().
