<p class=MsoNormal>Ok, <o:p></o:p></p>

<p class=MsoNormal>&nbsp; I am trying to get a redirect server working
correctly, only cache is I need to hit another redirect server first, and grab
info from the contact in the that 302 reply before processing and sending back
a 300 to the original switch. &nbsp;<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>call flow would be something like this:<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>call comes into kamailio, <o:p></o:p></p>

looks at the contact header of the 302 reply, <o:p></o:p></p>

<p class=MsoNormal>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 5)&nbsp;
&nbsp;depending on that info, I decide where to tell the originating switch
where to go,<o:p></o:p></p>

<p class=MsoNormal>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 5)&nbsp;&nbsp;&nbsp;
kamailio sends originating switch a 300 redirect with new contact header. <o:p></o:p></p>

<p class=MsoNormal>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 6)&nbsp;&nbsp;
originating switch sends back ACK. <o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>I have tried doing this with a &nbsp;first step going to route(1)
, which does a &#8220;t_on_reply&#8221; and &#8220;t_relay&#8221; to the second
proxy. <o:p></o:p></p>

<p class=MsoNormal>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The
onreply route, graps the contact saves it into variable and then sends to
route(2), <o:p></o:p></p>

<p class=MsoNormal>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Route(2)
looks at the variable, does some other lookups and sends t_reply(&#8220;300&#8221;,&#8221;redirect&#8221;).
<o:p></o:p></p>

<p class=MsoNormal>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The
switch then sends the ACK, but kamailio says its not a local ACK and ignores
it.. <o:p></o:p></p>

<p class=MsoNormal>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Then
it keeps sending 300&#8217;s back to the switch&#8230; <o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>Please help.. Thanks in Advance. <o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>
