Negotiating Human Language in Real-Time Communications
RFC 8373, “Negotiating Human Language in Real-Time Communications”, is a Proposed Standard document published in May 2018 by R. Gellens. It has since been updated by RFC 8865. The canonical text is published by the RFC Editor.
Abstract
Users have various human (i.e., natural) language needs, abilities, and preferences regarding spoken, written, and signed languages. This document defines new Session Description Protocol (SDP) media- level attributes so that when establishing interactive communication sessions ("calls"), it is possible to negotiate (i.e., communicate and match) the caller's language and media needs with the capabilities of the called party. This is especially important for emergency calls, because it allows for a call to be handled by a call taker capable of communicating with the user or for a translator or relay operator to be bridged into the call during setup. However, this also applies to non-emergency calls (for example, calls to a company call center).
This document describes the need as well as a solution that uses new SDP media attributes.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
