I read this and the companion enumservice. My comment is similar to Cullen - I cannot understand the use case of why we need this. Just because something is a parameter today in the PSTN doesn't mean we need it in VoIP. I'd like to see the call flows and reasons why someone would look at this, what they'd do with it, and how it gets set. Also, as a general comment, I'm not sure I agree that this is a tel URI parameter. There is this increasing trend that says, "if I need parameter foo which was previously carried in ISUP, all I need to do is make it new foo parameter of the tel URI". In many cases these things are wholly inappropriate as tel URI parameters since they aren't qualifiers of the resource identified by the URI at all. One litmus test on this is - does the parameter make sense if the URI were a SIP URI like sip:jdrosen@cisco.com? If it still makes sense in that context you know for sure it shouldn't be a tel URI. -Jonathan R. -- Jonathan D.
