"... the goal of the WG is just to specify the RUE..." isn't consistent with the charter which, talks of a "a RUM-compliant provider" and the document scope which contains things like "the provider MUST". 

I don't think we will need to peer inside provider's networks except to point out - as we have - that there are some limitations on what codecs can realistically be offered at the provider's side of the RUE interface.

I think the text will need to recognise - as previous versions have done - some asymmetry between the RUE which is new and providers which are established.

Best regards

James

I agree that we need to clarify that requirements differ between the RUE
and the VRS provider. I think it is worth some discussion if the
provider should be "WebRTC-compatible" or perhaps something more
specific than that though not all the way to "WebRTC endpoint".

While the goal of the WG is just to specify the RUE, I think it may well
be helpful to specify (somewhere) more about the environment in which it
will be used, including the other pieces that play in that environment
and interact with the RUE. For instance media relays, Interactive Media
Response devices, Communications Assistant devices, video mail devices.

That will allow us to discuss constraints on the RUE that we need to
consider and/or the potential need to develop requirements for some of
those other devices.

        Thanks,
        Paul
