Hello. ?I wrote a simple app using python and pjsua. Which way one must hangup a call? Do i have to wait after " status = py_pjsua.call_hangup(call_id, 0, None, None) " call until callback on_call_state return that call is in py_pjsua.PJSIP_INV_STATE_DISCONNECTED state ? I have a debug listing of my app where call to ? ?status = py_pjsua.call_hangup(call_id, 0, None, None) returned status => 0 but a call still alive and in active state. In my app right after ? py_pjsua.call_hangup(...), approx 100 lines of python code later app start a new call with call_make_call without waiting a callback to return that previous call is disconnected. From time to time it happens that call_hangup returns 0 but a call keeps living in active state .. state text EARLY.. and total duration increments. i can send my app log if it needed. For now i am just checking all calls and if call in state EARLY and total duration > 50 i am trying to hang up it again. So how do i work it around? ( If i have to wait for to call which i hangup with status = py_pjsua.call_hangup and status => 0, i am afraid of getting stucked in waiting forever for some buggy call to disconnect, otherwise if not waiting i will end up with no free calls in pool, so i am now not waiting but trying to clean buggy calls, is there a better solution?) By the way, even in cleaner function py_pjsua.call_hangup returned 0 for about a 5 times and total call duration before actual disconnect callback happened is 84 seconds while first hangup_call was at total duration 50 seconds. --------------------------------------------------------------------- And also i have an annoying ????????pjsua_call.c Timed-out trying to acquire PJSUA mutex (possibly system has deadlocked) in pjsua_call_get_info() in pjsua log. What does this mean? Two threads entered pjsua_call_get_info simultaneously? Looking at the time i suspected it happens when i am calling and call is not yet confirmed. I am have on_call_state callback (where a call to ci = py_pjsua.call_get_info(call_id) is) and also i am polling pjsip from my app in while loop.. ( also ci = py_pjsua.call_get_info(call_id) ).. but i did set up Semaphore object and every call to py_pjsua.call_get_info protected with .acquire() in blocking mode. ????????(in fact the whole on_call_state callback def is inside .acquire() .release() ... and the whole snip that is polling ????????with ci = py_pjsua.call_get_info(call_id) is in .acquire() .release() ( as long as ci is used ) ?) ????????What other calls to py_pjsua i must take as critical area?
