Re: [Ecrit] country specific emergency URNs

[Henning Schulzrinne <[e-mail]>]

Vasil,

the service URN does not prescribe any network priority treatment. Indeed,
at least in the US, landline 911 calls are treated exactly the same as
regular calls, e.g., during network congestion. (We have the SIP RPH
mechanism for prioritizing call treatment, but it's not used for civilian
emergency calls.)

I suspect this is try for many of the non-112 calls today. I very much
doubt that marine emergency calls in Finland or 1-800 calls to the poison
control center in the US (and the equivalent set of numbers in Germany,
say) receive any priority treatment in the network.

Again, I think it helps make progress if we do not overload labels with
policy.

Naturally, any country or carrier is free to use any label, including the
URN, to signify any treatment local law and regulation permits or requires.
But the label does not *require* or imply such network treatment.

I admit I'm thoroughly confused by this discussion. Where did the priority
issue suddenly come from? It's not in any ECRIT document that I'm aware of.
