<div class="im">> if a user wants to make a call to the pstn, where does he define the<br>> originator of the call? in the from header? or using a RPID? i'm quite<br>> confuse aboout this?<br><br></div>Hi, this is not the correct question. A user is not a trusted node in<br>
the network (usually) so the user should just set the mandatory From<br>header (and maybe the P-Preferred-Identity). Its outboud proxy is the<br>responsible of asserting the identity of the originator (the user) and<br>can append a P-Asserted-Identity or Remote-Party-Id header containing<br>
the asserted identity (AoR). The proxy should ignore and remove any<br>PAI or RPID header in a request coming from a user (a NON trusted<br>node).<br>The proxy would then route the call to some PSTN gateway which trusts<br>
the proxy and uses the PAI or RPID value as call line identifier.<br><br>NOTE: The RPID header is *NOT* a standard. It's widely used but a new<br>deployment should move to the standard: P-Asserted-Identity.<br><br>For more information about how all this stuf works, please read RFC<br>
3325 in which *every* detail is fully explained.<br><font color="#888888"><br>--<br>Iņaki Baz Castillo<br><<a href="mailto:ibc@aliax.net">ibc@aliax.net</a>><br></font></blockquote></div><br>
