<p class="MsoNormal" style="margin-left:35.4pt">Hello everybody!<br>
<br>
Kamailio works as a Registrar. Additionally, rtpengine is deployed next to it. Using rtpgngine module I proxy media stream via rtpengine(rtpengine_manage()). I change SDP. SiP2SIP calls work fine. Now I would like to have possibility to "wake up" sip-clients(at
the android and ios phones) which are usually not on-line via push notification. Trying to use TSILO module. <br>
<br>
# User location service<br>
route[LOCATION] {<br>
lookup("location"); <br>
$var(rc) = $rc;<br>
if (is_method("INVITE")) <br>
{<br>
if (t_newtran()) <br>
{<br>
ts_store(); # if it a new transuction ,it will be store for some time.<br>
}<br>
}<br>
switch ($var(rc)) <br>
{<br>
case 1:<br>
route(RELAY);<br>
break; <br>
case -1:<br>
break;<br>
case -3:<br>
send_reply("404", "Not Found");<br>
exit;<br>
case -2:<br>
send_reply("405", "Method Not Allowed");<br>
exit;<br>
}<br>
}<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-left:35.4pt"><br>
# Handle SIP registrations<br>
route[REGISTRAR] {<br>
if (!is_method("REGISTER")) return;<br>
if (!save("location")) <br>
{<br>
sl_reply_error();<br>
}<br>
ts_append("location", "$tu"); # if transuction for this sip-client is exist. The invite will be send. <br>
exit;<br>
}<o:p></o:p></p>
</div>

If the client is not registered at the kamailio during the call. Then such calls are stored through the "ts_store" function for some time. And if during this time the client send register, kamailio will be sent INVITE to it. But I have the problem. Such calls
after "wake up"go through a special branch route that I don't know how to intercept. As a result, I can't change SDP(using rtpengite_manage commands) and rtp stream do not proxy via rtpengine… and call failed.<o:p></o:p></p>
