Hi everbody,
I read (downloaded and tried) almost the entire b4a site looking for a really working example for phoneevents with dual sim calling


This is the code used to call
B4X: 
'sim = 0 SIM1, = 1 SIM2
Sub Call_SIM(num As String, sim As Int)
Dim i As Intent
i.Initialize(i.ACTION_CALL, "tel:" & num)
i.putExtra("simSlot", sim)
i.putExtra("com.android.phone.force.slot", True)
i.putExtra("Cdma_Supp", True)
i.putExtra("com.android.phone.extra.slot", sim)
StartActivity(i)
End Sub

Can you help me?

Thanks in advance

Ok... if so I can change to a single sim
Is there somewhere a working example?
I need to call sequentially about five numbers (conference call) and re-call several time if one of them is busy

Ok, but which is the event have I to intercept for a busy phone?
I need to know to put it in a queue and recall the number at the end of the sequence.

Complicated or impossible, for b4a?

The native app of my smartphone intercepts these events

is there an expert who can solve this issue? (I can pay, obviously it depends on the price)

@Marco Gioia,
Android does not allow to detect that the call is answered. Answer machine is impossible.
You can only make call, and kill it.


B4X: 
Sub PE_PhoneStateChanged (State As String, IncomingNumber As String, Intent As Intent)
    Main.PhoneState = State

    'Log("State=" & State)
    'Log(Intent.ExtrasToString)
    
    If State = "RINGING" AND IncomingNumber<>"" Then 'incoming call
        Main.LastInNumber = IncomingNumber
        PhoneFlag = 1
        'Log("Incoming detected " & DateTime.Time(DateTime.Now))
        DoEvents
        'ToastMessageShow("Calling " & IncomingNumber, True)
        Return
    End If
    If State = "OFFHOOK" AND IncomingNumber="" AND PhoneFlag = 1 Then 'answering to incoming call
        PhoneFlag = 2
        Return
    End If
    If State = "OFFHOOK" AND IncomingNumber="" AND PhoneFlag = 0 Then    'outgoing call
        Main.LastInNumber = IncomingNumber
        PhoneFlag = 4
        WaitingTimer.Enabled = True
        Log("PhoneFlag = 4, out call")
        'AR.Start
        Return
    End If
    If State = "IDLE" AND Main.LastInNumber <> "" AND PhoneFlag = 2 Then 'just income call finished
        PhoneFlag = 3
        Return
    End If
    If State = "IDLE" AND Main.LastInNumber <> "" AND PhoneFlag = 1 Then 'just rejected income call
        PhoneFlag = 0
        Return
    End If
    If State = "IDLE" AND PhoneFlag = 4 Then 'just finished outgoing call
        PhoneFlag = 5
        Return
    End If       
    
    
    'Log("PhoneStateChanged, State = " & State & ", IncomingNumber = " & IncomingNumber & "; PhoneFlag = " & PhoneFlag)
End Sub

I haven't tried the app but I believe it is possible the app is probably using some kind of third-party services which provides this kind of services accessible through rest-api.

Also, it is not unheard of device manufacturers, such as Samsung and others, that opens "backdoors" against a fee. Read that TeamViewer had made a deal which let their software remotely control Samsung android devices.
