Hello, In my app I've decided to start and destroy pjsua in the separate thread to untie the UI. Is it okay if I do that in the new socondary thread every time as long as I call pj_thread_register? Or should I have one secondary thread hanging around, register it once, and make such calls from it? I mean, is it something wrong with registering short-lived threads that just make a call to pjsua and exit? Alexei
