Re: WG Review: Call Control UUI for SIP (cuss)

Hi Cullen,

the charter already says that the information "may be end-to-end
encrypted by the application". Therefore, proxies will not make any
decision (related or unrelated to call control) based on its contents
because the contents may simply not be available to the proxy.

Do you want the charter to be even more explicit about this?

Thanks,

Gonzalo

Basically do proxies need to be able to look at this to make decision about what they are going to do. We at least need a Yes/No answer to this question from the proponents of this work and the charter to make that clear.
