Publisher 401 Unauthorized rejects SUBSCRIBE, then sends update NOTIFY
----------------------------------------------------------------------
Key: XECS-1944
URL: http://track.sipfoundry.org/browse/XECS-1944
Project: sipXecs
Issue Type: Bug
Components: sipXpublisher
Environment: main stream FC8 development environment revision 14115
Reporter: Paul Mossman
Attachments: MWI_unauthorized_NOTIFY-filtered.pcap, PolycomFiles.zip,

I have a Polycom 430 registered to user 201, and I noticed two MWI (refresh)
SUBSCRIBEs failed un-expectedly. Later there was an MWI NOTIFY with this
failed Dialog ID.
See the attached MWI_unauthorized_NOTIFY-filtered.pcap.
- Frame 14: A message-summary SUBSCRIBE refresh (there are to and from
tags), and there is a Proxy-Authorization: header
- Frame 15: A 401 Unauthorized with a Www-Authenticate: header, but no
Content-Length: header (Why wouldn't the SUBSCRIBE have been accepted?)
- Frame 16: Another message-summary SUBSCRIBE refresh with the same
Proxy-Authorization: header as Frame 14, plus a Www-Authenticate: header with
nonce corresponding to Frame 15.
- Frame 17: Another 401 Unauthorized, similar to Frame 15, the notable
exception being that there is a Content-Length: header (Why wouldn't the
SUBSCRIBE have been accepted?)
- Note that there is no first NOTIFY, as would be seen if the SUBSCRIBE was
successful.
- At this point I left a message directly into user 201's mailbox (by
dialing 8201)
- Frame 19: A message-summary NOTIFY regarding the voicemail. This is
unexpected, since the subscription failed. Note that this message has the same
Dialog ID as Frames 14-17.
- Frame 20: Indeed the phone considers the subscription dead, and therefore
returns a 481 Call Leg/Transaction Does Not Exist.
