RE: [Sipping] I-D on service identification now available

["Francois Audet" <audet at nortel.com>]

I don't think we are talking the same thing.

If the proxy want to invoke it, it can easily put the full
blown SIP URI in a Route header.

What I'm really questioning is the usefulness of having a URN
as an alias for a SIP URI being signalling on the wire between
the UA and the proxy, just to be replaced by a SIP URI by that
proxy.

I'm just saying that that phone should be able to do that on it's 
own by having the URI being downloaded in the phone at provision
time.
