Duy,
 
I make all fixes in dev.java.net, but it appears that I only fixed one
halve of the problem. Please see CVS for an update
 
Regards,
 
Jeroen

	Hi Jeroen,
	 
	In which CVS did you fix? Is it 'dev.java.net'? I have just made
a cvs update there and retest and see that the problem still exists!
Please find attached the new log file, where I find following
interesting logs:
	 
	- The callee sends the 'REFER' request and receives a '202
Accepted' response. On receiving of the response the stack sets the
local tag to the remote one:
	DEBUG -
gov.nist.javax.sip.stack.SIPTransactionStack.isDialogCreated(SIPTransact
ionStack.java:413) [isDialogCreated : REFER returning true]

	DEBUG -
gov.nist.javax.sip.stack.SIPDialog.setLocalTag(SIPDialog.java:1293) [set
Local tag test_tag_0008345318
9530701611-3879682410491611-11-78554471:32113234:test_tag_0008345318]

	- Later on the callee receives a 'BYE' request and is unable to
respond because of local tag mismatch (local tag equals to remote tag):

	ERROR -
gov.nist.javax.sip.stack.SIPDialog.checkResponseTags(SIPDialog.java:2048
) [sipResponse.getToTag() = 32113234]

	ERROR -
gov.nist.javax.sip.stack.SIPDialog.checkResponseTags(SIPDialog.java:2051
) [this.localTag() = test_tag_0008345318]

	ERROR -
gov.nist.javax.sip.stack.SIPDialog.checkResponseTags(SIPDialog.java:2053
) [sipResponse.getFromTag() = test_tag_0008345318]

	ERROR -
gov.nist.javax.sip.stack.SIPDialog.checkResponseTags(SIPDialog.java:2056
) [this.remoteTag = test_tag_0008345318]

	best regards,
	Duy

	On second try, I did manage to reproduce this. It occurs when
the callee sends REFER.
	Fix in CVS
	 
	Regards,

		Duy,
		 
		I was unable to reproduce this problem using the latest
JAIN SIP 1.2 CVS sources and a modified simplecallsetup example.
		Are you using the latest sources? Can you share the
message log?
		 
		Regards,
		 
		Jeroen

			Hi,
			 
			I found a problem within the SIP stack while
trying to blind transfer a call by sending a REFER request on an
existing dialog. On receiving of a 202 Accepted response to the REFER
request, the SIP stack sets the local tag of the dialog to the remote
one (this behavior is wrong because the REFER request was sent on the
existing dialog and therefore the SIP stack should not change the local
tag!) All other requests that are sent by the remote side later can not
be responded any longer due to dialog's tag mismatch:
