<p class="MsoNormal">Hi Jeffrey,<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">To do something like that, you need to have in DR (as gateway) the AOR
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">used by the GW to register with. And after you do do_routing() you do
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">lookup(location).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Now the tricky part is to link them, as Drouting is IP/domain driven
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">while user location is AOR driven.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">So, in DR use as GW 127.0.0.1 (.2 and so on) - even if there is
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">something phony, it has to be a valid IP. Now, after do_routing() you
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">will have in RURI sip:<a href="mailto:DID@127.0.0.1">DID@127.0.0.1</a> which needs to be pushed into user
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">location. Do transform it into a valid AOR (to be used as search key by
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">user location), save the username part of RURI into a variable (for
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">later restoring) and strip it -> ruri = sip:127.0.0.1 .Further use some
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">subst/string transformation to do a static transformation from 127.0.0.N
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">to gwN string and build AOR as sip:gwN@opensips_domain. So, in your case
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">you will get sip:gw1@opensips_domain as an AOR that can be used for
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">lookup location (of course, your GW must register under the AOR of
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">sip:gw1@opensips_domain). After lookup(location) just restore the DID
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">back into username part -> sip:DID@gw_address .<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Basically the trick is to get a static mapping between the phony IPs you
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">put in DR (like 127.0.0.N) and the AORs used by the GW to register (like
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">gwN@opensips_domain), so you can link them.<o:p></o:p></p>
