So anyone can say “I claim that this is compliant to the spec.” (as a webrtc-compatible endpoint) — and it might not interoperate. Basically, this proposal assigns different names to the devices that implement both, and those that implement only one or none, but does that really further the cause of interoperability? Video codecs weren't part of the discussion when we introduced those terms. The obvious examples were ICE-Lite for gateways that reside at public IP addresses, and datachannel and video for POTS telephone gateways - and yes, also OPUS codecs for POTS gateways. (those that have *only* g.711 on the other side - there are better codecs in that environment too, where bridging to OPUS may make sense.) The theory is that those devices will exist and do what they will do no matter what we specify here, so we might as well We'll go through terminology in an hour or so in the meeting. > > David Singer > Manager, Software Standards, Apple Inc. > > _______________________________________________ > rtcweb mailing list > rtcweb@ietf.org > https://www.ietf.org/mailman/listinfo/rtcweb -- Surveillance is pervasive.
