[sr-dev] Migration of Open IMS Core to sip-router

[Dragos Vingarzan]

LOL!

agree with you and for sure a lot of people don't even make the 
difference between 110 and 112. From what I can tell, it's more of a use 
for inter-emergency-services calls.

Yet it would be embarrassing if your SIP proxy would crash when it gets 
such a crazy URN from some emancipated client.

Cheers,

    AFAIK (but I could be wrong) URN are used by endpoints.
    Real usage example:


    1) The user is in danger since the fridge is empty.

    2) He takes his "IMS-ready" phone and looks for "Emergency" menu.

    3) There he selects: "urn:ietf:params:urn:emergeny:human:no-food"

    4) The hyper-intelligent phone sends automatically a PUBLISH to all its
      watchers containing a header "Accept: Burger" and body:

       <dm:person id="hyper-cool-ietf-ims-oma-phone">
         <rpid:activities>
           <rpid:hungry/>
         </rpid:activities>
         <dm:note>Food please</dm:note>
      </dm:person>

    5) The phone also makes a call to all the proxies close to it with URI:
        "urn:ietf:params:urn:emergeny:human:no-food"

    6) The proxy translates that URI into "sip:112 at LEGACY_GW_IP" and
    routes the
      call.

    7) When the emergency service answers the call, a voice + video +
    MSRP session
      is started. Nothing works due to NAT.

    8) At the same time some IETF member is writting a draft about "urns"
      uri called:
        "draft-ietf-i-am-cool-because-i-write-drafts-secure-urn.txt"
