-// This sub-API supports the following functionalities:

-//  - Telephone event transmission.
-//  - DTMF tone generation.
-//
-// Usage example, omitting error checking:
-//
-//  using namespace webrtc;
-//  VoiceEngine* voe = VoiceEngine::Create();
-//  VoEBase* base = VoEBase::GetInterface(voe);
-//  VoEDtmf* dtmf  = VoEDtmf::GetInterface(voe);
-//  base->Init();
-//  int ch = base->CreateChannel();
-//  ...
-//  dtmf->SendTelephoneEvent(ch, 7);
-//  ...
-//  base->DeleteChannel(ch);
-//  base->Terminate();
-//  base->Release();
-//  dtmf->Release();
-//  VoiceEngine::Delete(voe);
