Even though 711 quality actually sucks. I only mention 722 ..AMR WB btw since it's obvious that if you may want to interoperate with the several billion mobile endpoints that may be deploying VoLTE over the next few years. It might prove useful, unless this entire exercise is about creating N squared silos. You are still going to have to define a MUST support video codec eventually so just get on with it ..saying VP8 only is just unrealistic. -----Original Message----- From: rtcweb-bounces@ietf.org [mailto:rtcweb-bounces@ietf.org] On Behalf Of Jonathan Rosenberg Sent: Friday, August 17, 2012 1:02 PM To: Matthew Kaufman Cc: Cullen Jennings (fluffy); rtcweb@ietf.org Subject: Re: [rtcweb] Confirmation of consensus on audio codecs I'll chime in here too - it'll surprise no one that I agree Opus should be MTI. I agree on G.711 as well, as this has realistically been the lingua franca for voip since the very beginning. Its easy to put in, no IPR and will help with the many interop scenarios which the market will eventually want. Even if intermediaries are needed on the media path for other things - like ICE interop - at least we won't need transcode. -Jonathan R.

OPUS because it will be the IETF standard for wideband audio on the Internet, G.711 for maximum interoperability. G.722 is a reasonable thing to put on the "SHOULD" list... there's some other good choices for the SHOULD list, but they unfortunately come with additional IPR issues. > > Matthew Kaufman > > -----Original Message----- > From: rtcweb-bounces@ietf.org [mailto:rtcweb-bounces@ietf.org] On > Behalf Of Bernard Aboba > Sent: Thursday, August 16, 2012 5:42 PM > To: rtcweb@ietf.org > Cc: Cullen Jennings (fluffy); rtcweb@ietf.org > Subject: Re: [rtcweb] Confirmation of consensus on audio codecs > > I also support the selection of OPUS and G.711 as MTI.
