Hello,
o Bert Fraterman [02/04/09 17:55]:
I'm making a SEMS module in C++, and when I sent my bye, I also
immediately stop the session:
this->dlg.bye();
this->setStopped();
This pattern is also used in other modules, like the voicemail.
Unfortunately, when the SIP message 200 OK is received from the client,
the AmSipDispatcher gives an error:
ERROR: [42074940] handleSipMsg (AmSipDispatcher.cpp:48): could
not dispatch reply: (Incoming 200 OK reply)
I suspect the AmSipDispatcher is trying to post an event to the already
stopped session. Clearly, I'm not
interested in this event, otherwise I would've waited for it.
Also, this is not a critical error (I believe the internal state machine
closes down the call properly), so I
would suggest to demote the error to a warning, or even to a debug
message (since it could be a very deliberate
choice not to wait for the event).
set unhandled_reply_loglevel in sems.conf (see sems.conf.sample):
# optional parameter: unhandled_reply_loglevel={error|warn|info|debug|no}
#
# the default application logic implemented in the applications is to stop
# the session right after sending BYE, without waiting for a reply. this
# leads to many log entries of the form
# ERROR: [b6fa6bb0] handleSipMsg (AmSipDispatcher.cpp:48): unhandled
# reply: [code:200;phrase:[OK];... ]
#
# This parameter sets the log lovel of unhandled positive (200 class)
replies.
#
# default: error
#
# unhandled_reply_loglevel=info
Is my statement correct, or am I closing down my session in the wrong
way?
Well, I do it the same way, and have not run into problems, even though
there is at least one case when it this is not correct: If BYE needs to
be authenticated. but it would be nice to modify the default processing
to wait until BYE is replied with FR or times out (is it on the tracker
already?).
Regards
Stefan
Thanks,
Bert
