Negotiating Human Language in Real-Time Communications
draft-ietf-slim-negotiating-human-language-03
Abstract
Users have various human (natural) language needs, abilities, and
preferences regarding spoken, written, and signed languages. When
establishing interactive communication ("calls") there needs to be a
way to negotiate (communicate and match) the caller's language and
media needs with the capabilities of the called party. This is
especially important with emergency calls, where a call can be
handled by a call taker capable of communicating with the user, or a
translator or relay operator can be bridged into the call during
setup, but this applies to non-emergency calls as well (as an
example, when calling a company call center).
This document describes the need and a solution using new SDP stream
attributes.
