<div>Hello all,</div>
<div> </div>
<div>There is something I can’t understand using Kamailio as proxy to route SUBSCRIBE/NOTIFY dialogs between a client and a server</div>
<div> </div>
<div>I do record_route() on the first SUBSCRIBE received by Kamailio</div>
<div>The next SUBSCRIBE is well handled by Kamailio in the [WITHIN_DIALOG] bloc but the 200/OK no more contains record-route header</div>
<div>So the 3<font size="1"><span style="font-size:6.65pt;"><sup>rd</sup></span></font> SUBSCRIBE no more sets a relevant route and Kamailio rejets it with a 404 ?</div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;"> </span></font></div>
<div>How to proceed so that 200/Ok within dialog still contains Record-route header ?</div>
<div> </div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;"> </span></font></div>
<div>Here are the piece of routing logic involved</div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;"> </span></font></div>
<div> if (is_method("PUBLISH|SUBSCRIBE")) {</div>
<div> record_route();</div>
<div style="text-indent:35.4pt;"> $ru = "sip:192.168.0.250:6070";</div>
<div style="text-indent:35.4pt;"> route(RELAY);</div>
<div style="text-indent:35.4pt;"> exit;</div>
<div> }</div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;"> </span></font></div>
<div>And the as-is route[WITHINDLG] function</div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;"> </span></font></div>
<div>route[WITHINDLG] {</div>
<div> if (has_totag()) {</div>
<div> # sequential request withing a dialog should</div>
<div> # take the path determined by record-routing</div>
<div> if (loose_route()) {</div>
<div>#!ifdef WITH_WEBSOCKETS</div>
<div> if ($du == "") {</div>
<div> if (!handle_ruri_alias()) {</div>
<div> xlog("L_ERR", "Bad alias <$ru>\n");</div>
<div> sl_send_reply("400", "Bad Request");</div>
<div> exit;</div>
<div> }</div>
<div> }</div>
<div>#!endif</div>
<div> route(RELAY);</div>
<div> }</div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;"> </span></font></div>
<div>Thanks for your help</div>
