What steps will reproduce the problem?
1. i use imsdroid, i see that when the call end ,the tsip_ssession_dtor will
destroy the session, and then destroy audio and video session, but it delay
about ten more seconds to be called, from the debug ,i learn that the stack
only destroy the session(tsip_ssession_dtor be called ) after some sip timer
come to end , finaly call tsip_transac_ict_OnTerminated.
2.
3.
What is the expected output? What do you see instead?
What version of the product are you using? On what operating system?
Please provide any additional information below.

as delay destroy time of sip session, the onplugindestroy function in java
will be delay, so if i have another call during this time , the audio and video
plugin may be destroyed at this time ,from the debug i see the destructor of
CallSession ,InviteSession, SIpsession ,MediaSessionMgr all be called at onece
after call end, but it delay to call those ctor in doubango C, so ,may it be
problem of swig jni mechanism ?
Any idear sir ?
thanks .

To be honest I don't understand the problem at all :)
The framework use reference counting mechanism which means that a C/C++ object
will be destroyed only after the "refcount" value reach zero.
When you make hangup a call the SIP "BYE" request will create a new client
transaction which has a reference on the INVITE dialog. And the dialog holds a
reference on of the SipSession.
This means that the dialog will be destroyed after the transaction object as
the later has a reference of the former.
In SIP after a client transaction receive a final response (in this case 2xx
BYE) you have raise a timer ("K") in order to absorb retransmission or
out-of-order requests. This means that or transaction object will only be
destroyed when the timer "K" timeout.
This said, InviteSession, CallSession ... are just C++ wrappers around ANSI-C
objects. The life-cycle of these object is managed by java garbage collector
which means that the dtors are only called when you no longer hold any
reference in our java code. Take care: The garbage collector will not collect
the objects immediately, it's system dependent.

the fallow is debug log .
we see mRefCount is 0 in time 10:50, but the destructor is called about 10
senconds later . so it delay to remove mediaSessionMgr plugins .

and the C++ destrouctor :
~CallSession():
~InviteSession():
:~SipSession():
called at 10:50 but the dtor in c is 20s later.

All is working as expected.
SipSession only holds a reference to "tsip_ssession_t". The ANSI-c dtor will be
called when the "refcount" value reach zero.
What is the problem?
