Title : Public Safety Answering Point (PSAP) Callbacks
Author(s) : H. Schulzrinne, et al.
Filename : draft-ietf-ecrit-psap-callback-01.txt

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 or for a
clarification. 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, then 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 addresses callbacks in a
limited fashion and thereby covers a couple of scenarios. This
document discusses some shortcomings and illustrates an extension.
