Re: Dialog's local tag wrongly replaced!

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(SIPTransactionStack.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

    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:

      javax.sip.SipException: Response tags dont match with Dialog tags
