 ******************************
 PJSUA2 is an object-oriented abstraction above ​PJSUA API. It provides high level API for constructing ​Session Initiation Protocol (SIP) multimedia user agent applications (a.k.a Voice over IP/VoIP softphones). It wraps together the signaling, media, and NAT traversal functionality into easy to use call control API, account management, buddy list management, presence, and instant messaging, along with multimedia features such as local conferencing, file streaming, local playback, and voice recording, and powerful NAT traversal techniques utilizing ​STUN, ​TURN, and ​ICE.
+
+PJSUA2 is implemented on top of PJSUA-LIB API. The SIP and media features and object modelling follows what PJSUA-LIB provides (for example, we still have accounts, call, buddy, and so on), but the API to access them is different. These features will be described later in this chapter. PJSUA2 is a C++ library, which you can find under ``pjsip`` directory in the PJSIP distribution. The C++ library can be used by native C++ applications directly. But PJSUA2 is not just a C++ library. From the beginning, it has been designed to be accessible from high level non-native languages such as Java and Python. This is achieved by SWIG binding. And thanks to SWIG, binding to other languages can be added relatively easily in the future.

 PJSUA2 Main Classes

 For platforms that require polling, the PJSUA2 module provides its own worker thread to poll PJSIP, so it is not necessary to instantiate own your polling thread. Having said that the application should be prepared to have the callbacks called by different thread than the main thread. The PJSUA2 module should be thread safe.

+Using in C++ Application
+========================
+As mentioned in previous chapter, A C++ application can use *pjsua2* natively, while at the same time still has access to the lower level objects and the ability to extend the libraries if it needs to. Using the API will be exactly the same as the API reference that is written in this book.
+
+Here is a sample complete C++ application to give you some idea about the API. The snippet below initializes the library and creates an account that registers to our pjsip.org SIP server.
+
+.. code-block:: c++
+    
+  #include <pjsua2.hpp>
+  #include <iostream>
+  
+  using namespace pj;
+  
+  // Subclass to extend the Account and get notifications etc.
+  class MyAccount : public Account {
+  public:
+      virtual void onRegState(OnRegStateParam &prm) {
+          AccountInfo ai = getInfo();
+          std::cout << (ai.regIsActive? "*** Register:" : "*** Unregister:")
+                    << " code=" << prm.code << std::endl;
+      }
+  };
+
+  int main()
+  {
+      Endpoint ep;
+      
+      ep.libCreate();
+      
+      // Initialize endpoint
+      EpConfig ep_cfg;
+      ep_cfg.uaConfig.userAgent = "pjsua2-hello";
+      ep.libInit( ep_cfg );
+      
+      // Create SIP transport. Error handling sample is shown
+      TransportConfig tcfg;
+      tcfg.port = 5060;
+      try {
+          ep.transportCreate(PJSIP_TRANSPORT_UDP, tcfg);
+      } catch (Error &err) {
+          std::cout << err.info() << std::endl;
+          return 1;
+      }
+      
+      // Start the library (worker threads etc)
+      ep.libStart();
+      std::cout << "*** PJSUA2 STARTED ***" << std::endl;
+      
+      // Configure an AccountConfig
+      AccountConfig acfg;
+      acfg.idUri = "sip:test@pjsip.org";
+      acfg.regConfig.registrarUri = "sip:pjsip.org";
+      AuthCredInfo cred("digest", "*", "test", 0, "secret");
+      acfg.sipConfig.authCreds.push_back( cred );
+      
+      // Create the account
+      MyAccount *acc = new MyAccount;
+      acc->create(acfg);
+      
+      // Here we don't have anything else to do..
+      pj_thread_sleep(10000);
+      
+      // Delete the account. This will unregister from server
+      delete acc;
+      
+      // This will implicitly shutdown the library
+      return 0;
+  }
