[OpenSIPS-Users] OpenSIPS and Apple Push Notification

[microx]

Hi,

I also encountered the same issue. What I do is create an external process
which communicates with the APNS server and receives requests from OpenSIPS
server. Specifically, when the SIP server receives an INVITE but fails to
lookup for the callee, the SIP server notifies the external process with the
callee SIP ID. Next, with the callee's SIP ID, the external process checks
whether the callee uses ios-version App. If so, the external process
retrieves the callee's APNS token based on the received SIP ID and sends an
notification with the token to the APNS server. If lucky, the callee invokes
the SIP-based VoIP app and receives some following SIP INVITE in time. I
hope that this would be helpful. Any comment is welcome.

if (!lookup("location","m")) {
     switch ($retcode) {
                case -1:
                case -3:
                    exec_avp("echo $tU,$ci | nc 10.100.13.12
externalProcessPort", "$avp(ios)");
                    xlog("iOS: $avp(ios)");
                    if ($avp(ios) != "1") {
                        t_newtran();
                        xlog("Invite: 404 Not Found");
                        t_reply("404", "Not Found");
                    }
                    exit;
                case -2:
                    sl_send_reply("405", "Method Not Allowed");
                    exit;
            }
 }

Best regards,
Chen-Che
