El Jueves, 11 de Diciembre de 2008, ingdavidcespedes@cable.net.co escribió:> SORRYYYYYYY, you were right. What i'm trying to say is that if the UA
insert the p-p-i and privacy headers, the proxy should understand
this and
do what I say above.
The user sends the request with: From: Anonymous sip:anonymous@XXXXXx P-Preferred-Identity: sip:alice@domain.com Privacy: id
Then the proxy knows who is by checking PPI header and could ask for credentiales. After it, the proxy would remove PPI before routing the request.
If the proxy sends the request to a trusted node, it could add PAI header: P-Asserted-Identity: sip:alice@domain.com Privacy: id
And the next element would remove it if it routes to an untrusted node/endpoint.
Agree with all that you say. Only that the "P-Preferred-Identity:" is optional. If it is not present, the proxy should add a predefined P-Asserted-Identity: header field, if it is going to send the request to a trusted node.
But as you can see, this implies different possible cases. So it would be very nice if we can do all of this using some module or something like that, don't you think so?
