Re: [reSIProcate] UA replied Bad evet 400 for NOTIFY

What do the resip logs say? Turn them up to DEBUG, and they usually do a pretty good job of indicating why they're rejecting a message.
That said, there are only a handful of places DUM can return a 400, and the vast majority of them have custom reason phrases (e.g., "Invalid auth header" instead of "Bad Request"). The select few that I can find that use the default phrase (ignoring ones that can't happen to a NOTIFY) are: 

  1. Missing Event header field (not the case here)
  2. Exception thrown during creation of a dialog (can't happen here,
     since the 200 response to the SUBSCRIBE created the dialog)
  3. The code you have written called "rejectUpdate()" on the
ClientSubscription without providing a reason phrase. I don't see any way the code can get to #1 or #2 under the circumstances you describe -- so I've either missed a case, or it's #3. Please make sure that your code isn't explicitly triggering the 400 by calling "rejectUpdate()".
[Related note to others: we should fix #1 and #2 so that they have explicit reason phrases indicating the error, instead of the default phrase -- "400" is a pretty frustrating error to troubleshoot; we need all the help we can get]

Hi all, I'm implemented the MWI for my UA:
mMasterProfile->addSupportedMethod(NOTIFY); mMasterProfile->addSupportedMethod(SUBSCRIBE); mMasterProfile->addSupportedMimeType(NOTIFY,Mime("message", "sipfrag")); mMasterProfile->addSupportedMimeType(NOTIFY, Mime("application", "simple-message-summary")); static const Data messageSummaryEvent("message-summary"); 
 mDum.addClientSubscriptionHandler(messageSummaryEvent, this);
mDum.addOutOfDialogHandler(OPTIONS, this); 
 mDum.addOutOfDialogHandler(NOTIFY, this);
but now, when the server send NOTIFY for MWI to UA, the UA replied 400 Bad event to server, why ?
