Re: [Linphone-developers] Notifications doesnt arrive on iOS after app goes to Background

[German Cancio]

Do you get CallKit launched? Does the client REGISTER with the server, does 
then the server send an INVITE to the client? Have you checked that the Call-ID 
provided in the APNS payload is exactly the same as the one the INVITE? In the 
log lines you provided, the Call-ID is empty. Also, loc-key should be IC_MSG 
not IM_MSG. 

Below is an example of what you should be sending and then receiving on the 
client:

2020-10-16 17:25:03:006 [CERNphone/ios] MESSAGE (honeAppDelegate.m:553 ) 
[PushKit] Notification [0x2803a9080] received with payload : {
    aps =     {
        "call-id" = “deadbeef-dead-beef-deadbeef";
        "loc-args" =         (
            ""
        );
        "loc-key" = "IC_MSG";
        "send-time" = "2020-12-06 12:00:00";
        sound = "";
        uuid = "<urn:uuid: deadbeef-dead-005d-9a77-9462cec3ba3f>";
    };
    "display-name" = "";
    "from-uri" = "";
    "pn_ttl" = 50;
}

So your forthcoming INVITE should have as Call-ID "deadbeef-dead-beef-deadbeef” 
in this example.
