[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]
