make a call - Ctelephony API

[marycore]

Hi all
I want to make a call for symbian ver 9.1 by using CTelephony API,

Here is the simple code:




CDialler::CDialler(): CActive(EPriorityStandard), iTelephony(NULL)
{

}


void CDialler::ConstructL()
{
iTelephony = CTelephony::NewL();
}


CDialler::~CDialler()
{
Cancel();
delete iTelephony;
}


void CDialler::SomeFunction()
{


CActiveScheduler::Add(this);
CTelephony::TTelNumber telNumber(KTheNumber);
CTelephony::TCallParamsV1 callParams;
callParams.iIdRestrict = CTelephony::ESendMyId;
CTelephony::TCallParamsV1Pckg callParamsPckg(callParams);
iTelephony->DialNewCall(iStatus, callParamsPckg, telNumber, iCallId);

SetActive();
}

void CDialler::RunL()
{
if(iStatus==KErrNone)
{

}
}

void CDialler:oCancel()
{
iTelephony->CancelAsync(CTelephony::EDialNewCallCancel);
}

=======
and I call the method in this way:

CDialler* iDialer = new (ELeave) CDialler();
CleanupStack::PushL(iDialer);
iDialer -> ConstructL();
iDialer -> SomeFunction();
CleanupStack::Pop(iDialer);

but no event without any error messages occures!
what should I do?

tnx

pls look at the memory management and cleanupstack in sdk
we do not call constructl directly
and often using NewL or NewLC instead of new (ELeave) for AO

[marycore]

thanks for your reply,
I change the code to this:

CDialler* CDialler::NewLC()
{
CDialler* self = new( ELeave ) CDialler;
CleanupStack::PushL( self );
self->ConstructL();
return self;
}


and change the caller to this:

CDialler* dlg = CDialler::NewLC();
CleanupStack::Pop();
dlg->SomeFunction();


but still It doesn't make any call without any error!
where is my problem?

Hi MaryCore,

do like this,

void CDialler::SomeFunction()
{


CActiveScheduler::Add(this);
CTelephony::TTelNumber telNumber(KTheNumber);
CTelephony::TCallParamsV1 callParams;
callParams.iIdRestrict = CTelephony::ESendMyId;
CTelephony::TCallParamsV1Pckg callParamsPckg(callParams);
iTelephony->DialNewCall(iStatus, callParamsPckg, telNumber, iCallId);

SetActive();
//iWait is CActiveSchedulerWait
if ( iWait.IsStarted() == (TInt)ETrue )
{
return;
}
else
{
iWait.Start();
}
}

or check IsvTelCallApp example in sdk example.

Dear eswar,
thanks, but the problem has not been solved!
and also I couldn't find the IsvTelCallApp example... .
I am using 3rd edition SDK. and the self signed sis file!

[eswar_illuri]

Hi MaryCore,

IsvTelCallApp example is in S60Ex folder in your 3rd edition SDK, Check it.

eswar

Hi Eswar
I found that example and built it.
after making a signed sis file I get this error during the installation:
"Required Application access not granted"

where is the problem reason?

[eswar_illuri]

Hi,

For this application u need developer certificate. And remove the capabilities ReadDeviceData and WriteDeviceData from .mmp file. For Developer Certificate register in www.symbiansigned.com

regards,
eswar

[marycore]

it means that self signed sis files can't work?

[eswar_illuri]

Hi,

Yes. Because self signed doesn't support some of the capabilities related to CTelephony. Check all the capabilities listed in the mmp file.

eswar
