[OpenSIPS-Users] Routing NOTIFY to the phone

[Michele Pinassi]

Hi all,

again on BLF...i noticed that after correct SUBSCRIPTION on the server
and on the phones of the monitored extension, when one of that change
its status, the NOTIFY was send to the server that reply with 404 and
*not* to the monitoring phone.

Here's a siptrace of what's happens:

Here's the part of opensips.cfg involved:

#### XCAP modules
loadmodule "xcap.so"
loadmodule "xcap_client.so"

modparam("xcap", "integrated_xcap_server", 1)

#### PRESENCE modules
loadmodule "presence.so"
loadmodule "presence_mwi.so"
loadmodule "presence_callinfo.so"
loadmodule "presence_xml.so"
loadmodule "presence_dialoginfo.so"

modparam("presence", "db_url", "mysql://")
modparam("presence", "server_address", "sip:voip.unisi.it:5060")

modparam("presence", "notify_offline_body", 1)
modparam("presence", "fallback2db", 1)
modparam("presence", "clean_period",  30)
modparam("presence", "mix_dialog_presence", 1)

modparam("presence_xml","force_active",1)

[...]
route {
[...]
    ### PRESENCE
    if(is_method("PUBLISH|SUBSCRIBE")) {
        route(handle_presence);
    }
[...]
}

# Presence route
route[handle_presence] {
    xlog("L_INFO","Route PRESENCE on $rm [$fd/$fu/$rd/$ru/$si/]\n");
    if(!t_newtran()){
        sl_reply_error();
        exit;
    }

    if (is_method("PUBLISH")) {
        if($hdr(Sender)!= NULL)
        handle_publish("$hdr(Sender)");
    else
        handle_publish();
    } else if (is_method("SUBSCRIBE")) {
        handle_subscribe();
   }

    exit;
}

How i can route NOTIFY to the right extensions ?

Thanks, Michele
