The IESG has received a request from the Real-Time Communication in WEB-browsers WG (rtcweb) to consider the following document: - 'Additional WebRTC audio codecs for interoperability.' <draft-ietf-rtcweb-audio-codecs-for-interop-05.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2016-03-09. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract To ensure a baseline level of interoperability between WebRTC endpoints, a minimum set of required codecs is specified. However, to maximize the possibility to establish the session without the need for audio transcoding, it is also recommended to include in the offer other suitable audio codecs that are available to the browser. This document provides some guidelines on the suitable codecs to be considered for WebRTC endpoints to address the most relevant interoperability use cases.
