Hi list,
I have a problem using pjsip (pjproject-2.3 release) via the pjsua2 cpp api:
Having implemented my own media port for transferring the data to and
from one of our systems (spoken dialog system), it happens that the
dialog management says to hang up a call. This of course happens in the
media callbacks (since that's where the communication with the dialog
system happens). Calling hangup() from this thread sometimes(!) leads to:
pjsua_call.c !.Timed-out trying to acquire dialog mutex (possibly
system has deadlocked) in pjsua_call_hangup().
Afterwards, the software crashes, so most likely something goes wrong
with deletion of the call object.
Is there any sort of locking I need to be doing in order to successfully
hang up from a media callback? Do I need to defer the hangup to another
thread altogether? I don't use any application mutexes, so according to
https://trac.pjsip.org/repos/wiki/PJSUA_Locks I should not need to do
anything there.
Any hints?
Regards,
Thomas
