Ballot Text

Technical Summary

Called parties often wish to decide whether to accept, reject or
redirect calls based on the likely nature of the call.  For example,
they may want to reject unwanted telemarketing or fraudulent calls,
but accept emergency alerts from numbers not in their address book.
This document describes SIP Call-Info parameters and a feature tag
that allow originating, intermediate and terminating SIP entities to
label calls as to their type, confidence and references to additional
information.

Working Group Summary

This document fits into the general area the stir working group has been addressing, but deal with the problem of how a user expresses their wishes to their service provider to handle incoming calls based on information mechanisms like stir would provide.  It is a simple extension to the existing Call-Info header and is a relatively uncomplicated document.  It had a relatively smooth path through the normal sipcore process and has generally been well received.

Document Quality

Several of the core sip experts have reviewed the document, but only offered relatively minor suggestions, which were incorporated in the text.

Personnel

Brian Rosen is the document shepherd.
Adam Roach is the responsible area director.
