#   value 'timer' but does not contain a Session-Expires header, it means

#   one.  The UAS may request a session timer in the 2XX response by
#   including a Session-Expires header field.  The value MUST NOT be set
#   to a duration lower than the value in the Min-SE header field in the
#   request, if it is present.
