I've been looking at the examples in
draft-ietf-sipping-config-framework-15, and I suspect that one is not
correct. Specifically, in section 7.1 is:
SUBSCRIBE sip:urn%3auuid%3a00000000-0000-1000-0000-00FF8D82EDCB
@example.com SIP/2.0
Event: ua-profile;profile-type=device;vendor="vendor.example.net";
model="Z100";version="1.2.3";
From: anonymous@example.com;tag=1234
To: sip:urn%3auuid%3a00000000-0000-1000-0000-00FF8D82EDCB@example.com
Call-ID: 3573853342923422@192.0.2.44
CSeq: 2131 SUBSCRIBE
Contact: sip:urn%3auuid%3a00000000-0000-1000-0000-00FF8D82EDCB
@192.168.1.44
;+sip.instance="<urn:uuid:00000000-0000-0000-0000-123456789AB0>"
;schemes="http,https"
Via: SIP/2.0/TCP 192.0.2.41;
branch=z9hG4bK6d6d35b6e2a203104d97211a3d18f57a
Accept: message/external-body, application/x-z100-device-profile
Content-Length: 0
As far as I can tell, 5.1.4.2, the user part of the request-URI must be
the "device identifier", which would be in this case
"urn:uuid:00000000-0000-1000-0000-00FF8D82EDCB". The +sip.instance
parameter of the Contact field must be the same as that in the local
network profile SUBSCRIBE request, which 5.1.4.1 refers to sip-outbound.
But it seems to me that the +sip.instance value is expected to be the
device identifier. And yet, in this example, it is different from the
device identifier in the request URI. I suspect that I'm not
understanding the concept behind this.
