After an emergency call is completed (either prematurely terminated
by the emergency caller or normally by the call-taker) it is possible
that the call-taker feels the need for further communication. For
example, the call may have been dropped by accident without the call-
taker having sufficient information about the current situation of a
wounded person. A call-taker may trigger a callback towards the
emergency caller using the contact information provided with the
initial emergency call. This callback could, under certain
circumstances, be treated like any other call and as a consequence it
may get blocked by authorization policies or may get forwarded to an
answering machine.
The IETF emergency services architecture offers capabilities to allow
callbask to bypass authorization policies to reach the caller without
unnecessary delays. However, the mechanism specified prior to this
document supports only limited scenarios. This document discusses
some shortcomings, presents additional scenarios where better-than-
normal call treatment behavior would be desirable, and specifies a
protocol solution.
