Title : A Session Initiation Protocol (SIP) Response Code for Rejected Calls
Authors : Eric W. Burger

Filename : draft-ietf-sipcore-rejected-09.txt
Pages : 25

Abstract:
This document defines the 608 (Rejected) SIP response code. This
response code enables calling parties to learn that an intermediary
rejected their call attempt. No one will deliver, and thus no one
will answer, the call. As a 6xx code, the caller will be aware that
future attempts to contact the same User Agent Server will likely
fail. The initial use case driving the need for the 608 response
code is when the intermediary is an analytics engine. In this case,
the rejection is by a machine or other process. This contrasts with
the 607 (Unwanted) SIP response code, which a human at the target
User Agent Server indicated the user did not want the call. In some
jurisdictions this distinction is important. This document also
defines the use of the Call-Info header field in 608 responses to
enable rejected callers to contact entities that blocked their calls
in error. This provides a remediation mechanism for legal callers
that find their calls blocked.
