Hi all,
I want to hook any outgoing call with CTelephony API.

I used this code...
But I get an error:
===================================================
#include <e32base.h>
#include <Etel3rdParty.h>

class CCallObserver : public CActive
{
public:
CCallObserver();
void RequestNotification();
void Construct();
private:
void RunL();
void DoCancel();
void WriteToFile(TInt aIndex);
private:
CTelephony* iTelephony;
CTelephony::TCallStatusV1 iLineStatus;
CTelephony::TCallStatusV1Pckg iLineStatusPckg;
};


CCallObserver::CCallObserver(): CActive( EPriorityStandard ),
iLineStatusPckg( iLineStatus )
{
iLineStatus.iStatus = CTelephony::EStatusUnknown;
}
void CCallObserver::Construct()
{
iTelephony = CTelephony::NewL();
CActiveScheduler::Add(this);
}
void CCallObserver::RequestNotification()
{
iTelephony->NotifyChange( iStatus, CTelephony::EVoiceLineStatusChange,
iLineStatusPckg );
SetActive();
}
void CCallObserver::RunL()
{
if( iStatus==KErrNone )
{
iTelephony->NotifyChange( iStatus,
CTelephony::ESignalStrengthChange, iLineStatusPckg );
SetActive();
}
}
========================================
if I comment the SetActive() method in RequestNotification() there is no
error but if it exists, I get App.Closed error!!!
where is the problem?
