Hello everybody!
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.
# User location service
route[LOCATION] {
lookup("location");
$var(rc) = $rc;
if (is_method("INVITE"))
{
if (t_newtran())
{
ts_store(); # if it a new transuction ,it will be store for some time.
}
}
switch ($var(rc))
{
case 1:
route(RELAY);
break;
case -1:
break;
case -3:
send_reply("404", "Not Found");
exit;
case -2:
send_reply("405", "Method Not Allowed");
exit;
}
}
# Handle SIP registrations
route[REGISTRAR] {
if (!is_method("REGISTER")) return;
if (!save("location"))
{
sl_reply_error();
}
ts_append("location", "$tu"); # if transuction for this sip-client
is exist. The invite will be send.
exit;
}
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.
