NUTAG_URL() should work for blind NOTIFYs but not with the SUBSCRIBEd
NOTIFYs. The latter take the URL from the Contact (or Record-Route)
header. However, they are part of an existing dialog, so your security
servers should let them through. (You may need to respond to SUBSCRIBE
before sending NOTIFY, however.)
