Getting Started

Building PJSUA2

The PJSUA2 C++ library will be built by default by PJSIP build system.

Building Python and Java SWIG Modules

The SWIG modules for Python and Java are built by invoking make and make install manually from pjsip-apps/src/swig directory. The make install will install the Python SWIG module to user site-packages directory.

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.

#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.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;
}
