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

Pages : 22

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. The call will not be answered. As a
6xx code, the caller will be aware that future attempts to contact
the same UAS will likely fail. The present 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 UAS indicated the call was not wanted.
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.
