I need to include a walki talkie in my app. I am always getting a registration failure -9 error code. I created 2 free Sip account (sip2sip.info, sip.linphone.org) and 1 commercial one (onsip.com). I added all those permission:

<uses-permission android:name="android.permission.CALL_PHONE" />

<uses-permission android:name="android.permission.INTERNET" />

<uses-permission android:name="android.permission.USE_SIP" />

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<uses-permission android:name="android.permission.RECORD_AUDIO" />

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />

and the following features:

<uses-feature android:name="android.hardware.sip.voip" android:required="true" />

<uses-feature android:name="android.hardware.wifi" android:required="true" />

<uses-feature android:name="android.hardware.microphone" android:required="true" />

I am calling the above fonction in the onCreate:

        SipProfile.Builder builder = new SipProfile.Builder(c.config().getSIP_UserName(), c.config().getSIP_Domain());

        builder.setPassword(c.config().getSIP_Password());



        //builder.setProtocol("UDP"); //"TCP");

        //builder.setPort(5060);   //5080  5070   

        builder.setAutoRegistration(true);



        mSipProfile = builder.build();

    }

I compile for Nougat because I am using deprecated function. Then I modified my code to compile with Oreo.
I used Firewall Voip Checker to check my connection with my SIP server and the test 1 is successful but the second one seam to be in an infinite loop. One of the result of the test one is captured my attention but I don't know what it means:

Check NAT type

100% / Blocked or could not reach STUN server (but it's green so I guess it pass the test??). I had the flag :

android.useDeprecatedNdk=true

I change it to false...
and I always get the return code "registration faild"

I hadded this fonction to see what the -9 error code was:

// FOR MORE DETAILS SEE
// Sip Error while registration
// How to send instant message via SIP
//https://developer.android.com/reference/android/net/sip/SipErrorCode
private String errCode(int iErrorCode)
{
String sErr = "";

    switch (iErrorCode)

    {

        case CLIENT_ERROR:

            sErr = "client error!!";

            break;

        case CROSS_DOMAIN_AUTHENTICATION:

            sErr = "cross domain authentification!!";

            break;

        case DATA_CONNECTION_LOST:

            sErr = "data connection lost!!";

            break;

        case INVALID_CREDENTIALS:

            sErr = "invalid credentials!!";

            break;

        case INVALID_REMOTE_URI:

            sErr = "invalid remote uri!!";

            break;

        case IN_PROGRESS:

            sErr = "In progress!!";

            break;

        case NO_ERROR:

            sErr = "No error!!";

            break;

        case PEER_NOT_REACHABLE:

            sErr = "peer not reachable!!";

            break;

        case SERVER_ERROR:

            sErr = "server error!!";

            break;

        case SERVER_UNREACHABLE:

            sErr = "server unreachable!!";

            break;

        case SOCKET_ERROR:

            sErr = "socket error!!";

            break;

        case TIME_OUT:

            sErr = "time out!!";

            break;

        case TRANSACTION_TERMINTED:

            sErr = "No transaction terminated!!";

            break;

        default:

            sErr = "No error detected!!";

            break;

    }



    return (sErr);

}

The error message is "In progress..." witch means that he is busy already but I don't know what it means.

I when thru the error code on Wikipedia to have clues of the potential problem:

https://en.wikipedia.org/wiki/List_of_SIP_response_codes#4xx.E2.80.94Client_Failure_Responses

I tried to find a SDK of a higher lever to implement my walki talki and found.

I search for the app wireshark but I only found it for a laptop and not for my android smartphone.

It's important for me to implement the walki talkie because I am creating a app to increase the security of primary school daycare and we need to communicate with each other.

I tried to change the port and the communication protocol and I tried the AutoRegistration flag to true.

I tried to make a phone call after the registration failed in case the open statement did the registration assuming it could be trying to register a second time.

I have no more idea!!

I will implementing a WIFI Walki Talki without a sip account.
Reference: stackoverflow.com/questions/11176988/…

Then I will save, on startup, the port information, ip adresse, username of every smart phones (use by my collegue) into my firebase (online database) in order to establish communication without asking anything to the user to make it automatique.

I am realizing that if I have trouble connecting with sample code that is suppose to work this probably means that my clients will have the same kinds of problemes wish I want to avoid.

I don't need to communicate with people that are not on the same network but I think this method would also work over the internet even for cliente that are on an other router if they are all connected to the internet.
