New issue 15 by [email protected]: Problem when delivering TC-NOTICE
event in TCAP RA
http://code.google.com/p/jain-slee/issues/detail?id=15
TC-NOTICE occures when SCCP returns SCCP message (or it's segment) if SCCP
can not deliver it.
Then TCAP tried to decode a message and extract transactionId to recognize
which dialog it refers
We can get a dialog if it is a first part of SCCP segment and a Dialog has
not been released (for example after sending TC-END a dialog is released)
Other info that TC-NOTICE carries is SCCP calling and called parties
addresses and a cause why the message has not delivered
Even if we can not obtain a dialog SCCP addresses and cause can help us to
make some administartive actions for example for rerouting messages
So it looks like that Dialog absence is an ordinary case in TC-NOTICE
But in TCAP RA layer we need a non-null Dailog for TCAPDialogWrapper
creating and if dialog==null we will have an Exception here.
We need to fix somehow this.
