I would show some additional info, the idea is to make asynchronous a db query and some UAC notification message,
kamailio is v4.2.5, below is the relevant part of my code:
route[REGISTRAR] {
if (is_method("REGISTER"))
{
if(isflagset(FLT_NATS))
{
setbflag(FLB_NATB);
}
if (!is_avp_set("$avp(received)"))
{
$avp(received) = "sip:" + $si + ":" + $sp + ";transport=" + $proto;
}
# Save and update the contact information
if (!save("location", "0x04"))
sl_reply_error();
if(@contact.expires) {
$var(expires) = @contact.expires;
} else {
if(is_present_hf("Expires")) {
$var(expires) = $hdr(Expires);
} else {
$var(expires) = 300;
}
}
if($var(expires) == 0) {
xlog("L_INFO", "$ci|end|unregister request from $Au $si:$sp");
$avp(s:subs_from) = $fU;
$avp(s:subs_status) = "Offline";
route(PUSH_NOTIFICATION);
exit;
}
$avp(s:subs_from) = $fU;
$avp(s:subs_status) = "Online";
route(PUSH_NOTIFICATION);
Se cambio la async_route() con una semplice route() tutto funziona correttamente.
route[PUSH_NOTIFICATION] {
async_route("ASYNC_PUSH_NOTIFICATION_USERCONTACTS", "5");
}
route[ASYNC_PUSH_NOTIFICATION_USERCONTACTS] {
$var(subs_to) = $avp(s:subs_from);
xlog("L_INFO", "Request contacts push notification for $var(subs_to)");
sql_query("ca", "select contact from contactsmap where username = '$var(subs_to)'", "ra");
if($dbr(ra=>rows)>0)
{
$var(i) = 0;
while($var(i) < $dbr(ra=>rows))
{
$avp(s:subs_from) = $dbr(ra=>[$var(i),0]);
$avp(s:subs_to) = $var(subs_to);
xlog("L_INFO", "Checking presence of $avp(s:subs_from)");
if(registered("location", "sip:$avp(s:subs_from)@test.net"))
{
xlog("L_INFO", "Username $avp(s:subs_from) is registered sending push notification");
route(send_event_notify_presence);
}
else
{
xlog("L_INFO", "Username $avp(s:subs_from) is not registered, skipping");
}
$var(i) = $var(i) + 1;
}
}
sql_result_free("ra");
t_release();
}
route[send_event_notify_presence]
{
xlog("L_INFO", "request to send NOTIFY from $avp(s:subs_from) to $avp(s:subs_to)");
$uac_req(method) = "NOTIFY";
$uac_req(ruri) = "sip:" + $avp(s:subs_to) + "@test.net";
$uac_req(turi) = "sip:" + $avp(s:subs_to) + "@test.net";
$uac_req(furi) = "sip:" + $avp(s:subs_from) + "@test.net";
$uac_req(ouri) = "sip:test.net:5060";
$uac_req(hdrs) = "Event: voneus-contact-status\r\nVoneus-Status: " + $avp(s:subs_status) + "\r\n";
$uac_req(body) = "";
return uac_req_send();
}
and the corresponding backtrack I've got:
