If you use pjsua then by default it will instantiate the sound device. The sound device is then connected to the bridge, and it's actually the one that triggers the get_frame()/put_frame() calls. So if the sound device gets stucked, then no get_frame()/put_frame() will happen. Yes you can just give pjsua --null-audio option to disable sound device. pjsua then will use thread rather than sound device to push/pull frames. You will not hear audio in your speaker of course.
