Overview

This snippet demonstrates how to make a voice call with CTelephony::DialNewCall() and then disconnect the call using CTelephony::Hangup() from etel3rdparty.lib. Note that you can only disconnect calls that have been initiated by your application using the Telephony ISV API (CTelephony).

MMP file

The following libraries and capabilities are required:

CAPABILITY NetworkServices
LIBRARY etel3rdparty.lib // Telephony ISV API

Header

#include <Etel3rdParty.h> // Telephony ISV API
 
class CYourCall : public CActive
        {
    public:
        CYourCall();
        virtual ~CYourCall();
        void ConstructL();
        void HangUpL();
        void Dial(const TDesC& aNumber);
 
    protected:
        void DoCancel();
        void RunL();
 
    private:
        // Telephony ISV API
        CTelephony*                     iTelephony;
        CTelephony::TCallId iCallId;
        TBool iHangedUp;
        };

Source

CYourCall::CYourCall()
:CActive(CActive::EPriorityStandard)
    {
    }
 
CYourCall::~CYourCall()
    {
    Cancel();
 
    delete iTelephony;
    }
 
void CYourCall::ConstructL(void)
    {
    CActiveScheduler::Add(this);
    iTelephony = CTelephony::NewL();
    }
 
void CYourCall::DoCancel()
    {
    iTelephony->CancelAsync(CTelephony::EDialNewCallCancel);
    }
 
 
void CYourCall::RunL()
    {   
    if (iStatus.Int()==KErrNone && !iHangedUp)
        HangUpL();
    }
 
void CYourCall::Dial(const TDesC& aNumber)
    {
    // Dial new call with given number
    CTelephony::TTelNumber telNumber(aNumber);
 
    CTelephony::TCallParamsV1 callParams;
    callParams.iIdRestrict = CTelephony::ESendMyId;
    CTelephony::TCallParamsV1Pckg callParamsPckg(callParams);
 
    iTelephony->DialNewCall(iStatus, callParamsPckg, telNumber, iCallId);
    SetActive();
    }
 
void CYourCall::HangUpL()
    {
    if (IsActive())
        return;
 
    // Hang up call right after CTelephony::DialNewCall() is completed
    iHangedUp = ETrue;
    iTelephony->Hangup(iStatus,iCallId);
    SetActive();
    }

How to use

iCallMonitor = new (ELeave) CYourCall();
CleanupStack::PushL(iCallMonitor);
iCallMonitor->ConstructL();
CleanupStack::Pop();
 
iCallMonitor->Dial(_L("05012345678"));

Postconditions

The call is connected and then disconnected.
