I don't remember all the details of this discussion, but I'm not sure  
I understand this one. There is currently no W3C API for _receiving_  
DTMF, and no use case driving one, so I don't know what you would  
decorate a remote stream you are receiving with.

To be clear, the DSCP is probably an IETF matter (and certainly  
including it in the SDP is). Enforcement in the UA's network subsystem  
might be, depending on how much of that rmcat needs to standardize.
