Make a voice call

This sample application demonstrates how to make a voice call.

1. Implement ResponseCallback interface to receive subsystem initialization status

std::promise<telux::common::ServiceStatus> cbProm = std::promise<telux::common::ServiceStatus>();
void initResponseCb(telux::common::ServiceStatus status) {
   if(subSystemsStatus == SERVICE_AVAILABLE) {
      std::cout << Call Manager subsystem is ready << std::endl;
   } else if(subSystemsStatus == SERVICE_FAILED) {
      std::cout << Call Manager subsystem initialization failed << std::endl;
   }
   cbProm.set_value(status);
}

2. Get the PhoneFactory and Call Manager instance

auto &phoneFactory = PhoneFactory::getInstance();
auto callManager = phoneFactory.getCallManager(initResponseCb);
if(callManager == NULL) {
   std::cout << " Failed to get Call Manager instance" << std::endl;
   return -1;
}

3. Wait for Call Manager subsystem to be ready

telux::common::ServiceStatus status = cbProm.get_future().get();
if(status != SERVICE_AVAILABLE) {
   std::cout << Unable to initialize Call Manager subsystem << std::endl;
   return -1;
}

4. Optionally, implement IMakeCallCallback interface to receive response for the dial request

class DialCallback : public IMakeCallCallback {
public:
   void DialCallback::makeCallResponse(ErrorCode error, std::shared_ptr<ICall> call) {
      // will be invoked with response of makeCall operation
   }
};
std::shared_ptr<DialCallback> dialCb = std::make_shared<DialCallback> ();

5. Send a dial request

if(callManager) {
   std::string phoneNumber("+18989531755");
   int phoneId = 1;
   auto makeCallStatus = callManager->makeCall(phoneId, phoneNumber, dialCb);
   std::cout << "Dial Call Status:" << (int)makeCallStatus << std::endl;
}
