<p class="MsoNormal">Hello Ben<br>
<br>
I understand you add the npdi useraname parameter after performing the initial do_routing() - if you do it in request or branch route is not relevant (for RURI changes) as RURI is anyhow a per-branch value.<br>
In failure route, when resuming, you will get the RURI of the winning branch ( the one which was selected to be sent back to caller), so you see the npdi param.
<br>
<br>
So far so good. And now you do use_next_gw() in failure route and you get "<span style="font-size:11.0pt"><a href="sip:+15555551212@gw2.com;npdi">sip:+15555551212@gw2.com;npdi</a>" directly, without any another npdi addition ? I'm asking, as use_next_gw() does
a full RURI replacement (it doesn;t care what is the existing RURI).<br>
<br>
Could you also do an<br>
xlog("DR ruris are <$(avp(___dr_ruri__)[*])>\n");<br>
right after do_routing() ?<br>
<br>
Regards,<br>
<br>
