Extensions plug-in package for S60 3rd Edition SDK for Symbian OS, for C++, MR
Extensions plug-in package for S60 3rd Edition SDK for Symbian OS, for C++, supporting FP1

Solution

The below code shows how to load the PhoneClientExt DLL and how to construct and use a command handler (CPhCltCommandHandler) to mute the microphone.
Required capability: WriteDeviceData
    /*** Header file ***/
    #include <RPhCltServer.h>   // link against PhoneClient.lib
    #include <PhCltExt.h>       // link against PhoneClientExt.lib
    ...

    RPhCltServer iPhoneClientServer;
    RLibrary iLibrary;
    CPhCltCommandHandler* iPhCommandHandler;
    /*** Source file ***/
    _LIT(KPhoneCltExDllName, "PhoneClientExt.dll");
    User::LeaveIfError( iPhoneClientServer.Connect() );
    User::LeaveIfError( iLibrary.Load(KPhoneCltExDllName) );
    TInt res = iLibrary.Lookup(1)();
    CPhCltExtFactory* phCltExtFactory = reinterpret_cast<CPhCltExtFactory*>( res );
    iPhCommandHandler = phCltExtFactory->CPhCltCommandHandlerLD();
    User::LeaveIfError( iPhCommandHandler->Open( iPhoneClientServer ) );
    // Mute the microphone. This should be done inside an active object
    // (a class derived from CActive)
    iPhCommandHandler->MuteMicrophone( iStatus, ETrue );
    SetActive();
