E71 doesn't send the scan codes for number keys so the same has to be translated from the scan codes to get the numeric keys.

TInt CYourContainer::OfferKeyEventL(const TKeyEvent& aKeyEvent, TEventCode aType)
	{
        TInt key = aKeyEvent.iScanCode;
	switch (key)
		{
		case 'R':
			key = '1';
		case 'T':
			key = '2';
		case 'Y':
			key = '3';
		case 'F':
			key = '4';
		case 'G':
			key = '5';
		case 'H':
			key = '6';
		case 'V':
			key = '7';
		case 'B':
			key = '8';
		case 'N':
			key = '9';
		case 'M':
			key = '0';
		case 'U':
			key = '*';
		case 'J':
			key = EStdKeyHash;
		default:
			key = key;
		}
	}

The key mapped after this would have the numeric keys. The same would be useful for a developer writing dialer applications/number selection/entering dialogs, or any other cases where they want to take the numeric key inputs.
