[Linphone-developers] crash in liblinphone-iphone-sdk channel.c in background mode

[Vitaliy Dobroshtan]

Hi,

My name is Vitaliy, my team is struggling to solve one issue with the Linphone iOS SDK. Let me know please if you have an experience of fixing the same issue? 

Shortly about the problem:

We receive the crash in liblinphone-iphone-sdk channel.c line 518 when receiving a call, with the app running in background mode.

In app we use liblinphone-iphone-sdk v. 3.16.1. 

User registered on SIP-server successful.

transport: UDP

port: 5060

iOS 10.3 (iPhone 6s, iPhone 6+ devices)

Asterisk DialUP config template, logs from device, Asterisk and Fabric see in attachment.

On the server side, the following actions occur: 

1. Check user group.

2. Send wakeup push:

{

    aps =     {

        alert =         {

            "loc-key" = "IC_MSG";

        };

    };

    "call-id" = "call-id";

    fromName = enotded;

    fromNumber = 1010;

    params =     {

        concierge = 0;

    };

    type = wakeup;

}

3. Check concierge.

4. Check the settings for redirecting calls.

5. Send wakeup push:

{

    aps =     {

        alert =         {

            "loc-key" = "IC_MSG";

        };

    };

    "call-id" = "call-id";

    fromName = enotded;

    fromNumber = 1010;

    params =     {

        concierge = 0;

    };

    type = wakeup;

}

We can provide you more logs if needed.

I would really appreciate any help.

Thank you in advance,

Vitaliy
