| * @{ |
| * |
| * @section pjsua_api_intro A SIP User Agent API for C/C++ |
| * |
| * PJSUA API is very high level API for constructing SIP multimedia user agent |
| * applications. It wraps together the signaling and media functionalities |
| * into an easy to use call API, provides account management, buddy |
| * management, presence, instant messaging, along with multimedia |
| * features such as conferencing, file streaming, local playback, |
| * voice recording, and so on. |
| * |
| * @subsection pjsua_for_c_cpp C/C++ Binding |
| * Application must link with <b>pjsua-lib</b> to use this API. In addition, |
| * this library depends on the following libraries: |
| * - <b>pjsip-ua</b>, |
| * - <b>pjsip-simple</b>, |
| * - <b>pjsip-core</b>, |
| * - <b>pjmedia</b>, |
| * - <b>pjmedia-codec</b>, |
| * - <b>pjlib-util</b>, and |
| * - <b>pjlib</b>, |
| * |
| * so application must also link with these libraries as well. For more |
| * information, please refer to |
| * <A HREF="http://www.pjsip.org/using.htm">Getting Started with PJSIP</A> |
| * page. |
| * |
| * @section pjsua_samples |
| * |
| * Few samples are provided: |
| * |
| - @ref page_pjsip_sample_simple_pjsuaua_c\n |
| Very simple SIP User Agent with registration, call, and media, using |
| PJSUA-API, all in under 200 lines of code. |
| |
| - @ref page_pjsip_samples_pjsua\n |
| This is the reference implementation for PJSIP and PJMEDIA. |
| PJSUA is a console based application, designed to be simple enough |
| to be readble, but powerful enough to demonstrate all features |
| available in PJSIP and PJMEDIA.\n |
| |
| * @section root_using_pjsua_lib Using PJSUA API |
| * |
| * Please refer to @ref PJSUA_LIB_BASE on how to create and initialize the API. |
| * And then see the Modules on the bottom of this page for more information |

| * @brief Basic application creation/initialization, logging configuration, etc. |
| * @{ |
| * |
| * The base PJSUA API controls PJSUA creation, initialization, and startup, and |
| * also provides various auxiliary functions. |
| * |
| * @section using_pjsua_lib Using PJSUA Library |
| * |
| * @subsection creating_pjsua_lib Creating PJSUA |
| * |
| * Before anything else, application must create PJSUA by calling |
| * #pjsua_create(). |
| * This, among other things, will initialize PJLIB, which is crucial before |
| * any PJLIB functions can be called, PJLIB-UTIL, and create a SIP endpoint. |
| * |
| * After this function is called, application can create a memory pool (with |
| * #pjsua_pool_create()) and read configurations from command line or file to |
| * build the settings to initialize PJSUA below. |
| * |
| * @subsection init_pjsua_lib Initializing PJSUA |
| * |
| * After PJSUA is created, application can initialize PJSUA by calling |
| * #pjsua_init(). This function takes several optional configuration settings |
| * in the argument, if application wants to set them. |
| * |
| * @subsubsection init_pjsua_lib_c_cpp PJSUA-LIB Initialization (in C) |
| * Sample code to initialize PJSUA in C code: |
| \code |
| |
| #include <pjsua-lib/pjsua.h> |
| |
| #define THIS_FILE __FILE__ |
| |
| static pj_status_t app_init(void) |
| { |
| pjsua_config ua_cfg; |
| pjsua_logging_config log_cfg; |
| pjsua_media_config media_cfg; |
| pj_status_t status; |
| |
| // Must create pjsua before anything else! |
| status = pjsua_create(); |
| if (status != PJ_SUCCESS) { |
| pjsua_perror(THIS_FILE, "Error initializing pjsua", status); |
| return status; |
| } |
| |
| // Initialize configs with default settings. |
| pjsua_config_default(&ua_cfg); |
| pjsua_logging_config_default(&log_cfg); |
| pjsua_media_config_default(&media_cfg); |
| |
| // At the very least, application would want to override |
| // the call callbacks in pjsua_config: |
| ua_cfg.cb.on_incoming_call = ... |
| ua_cfg.cb.on_call_state = .. |
| ... |
| |
| // Customize other settings (or initialize them from application specific |
| // configuration file): |
| ... |
| |
| // Initialize pjsua |
| status = pjsua_init(&ua_cfg, &log_cfg, &media_cfg); |
| if (status != PJ_SUCCESS) { |
| pjsua_perror(THIS_FILE, "Error initializing pjsua", status); |
| return status; |
| } |
| . |
| ... |
| } |
| \endcode |
| * |
| * |
| |
| |
| * @subsection other_init_pjsua_lib Other Initialization |
| * |
| * After PJSUA is initialized with #pjsua_init(), application will normally |
| * need/want to perform the following tasks: |
| * |
| * - create SIP transport with #pjsua_transport_create(). Application would |
| * to call #pjsua_transport_create() for each transport types that it |
| * wants to support (for example, UDP, TCP, and TLS). Please see |
| * @ref PJSUA_LIB_TRANSPORT section for more info. |
| * - create one or more SIP accounts with #pjsua_acc_add() or |
| * #pjsua_acc_add_local(). The SIP account is used for registering with |
| * the SIP server, if any. Please see @ref PJSUA_LIB_ACC for more info. |
| * - add one or more buddies with #pjsua_buddy_add(). Please see |
| * @ref PJSUA_LIB_BUDDY section for more info. |
| * - optionally configure the sound device, codec settings, and other |
| * media settings. Please see @ref PJSUA_LIB_MEDIA for more info. |
| * |
| * |
| * @subsection starting_pjsua_lib Starting PJSUA |
| * |
| * After all initializations have been done, application must call |
| * #pjsua_start() to start PJSUA. This function will check that all settings |
| * have been properly configured, and apply default settings when they haven't, |
| * or report error status when it is unable to recover from missing settings. |
| * |
| * Most settings can be changed during run-time. For example, application |
| * may add, modify, or delete accounts, buddies, or change media settings |
| * during run-time. |
| * |
| * @subsubsection starting_pjsua_lib_c C Example for Starting PJSUA |
| * Sample code: |
| \code |
| static pj_status_t app_run(void) |
| { |
| pj_status_t status; |
| |
| // Start pjsua |
| status = pjsua_start(); |
| if (status != PJ_SUCCESS) { |
| pjsua_destroy(); |
| pjsua_perror(THIS_FILE, "Error starting pjsua", status); |
| return status; |
| } |
| |
| // Run application loop |
| while (1) { |
| char choice[10]; |

| printf("Select menu: "); |
| fgets(choice, sizeof(choice), stdin); |

| * |
| * PJSUA accounts provide identity (or identities) of the user who is currently |
| * using the application. In SIP terms, the identity is used as the <b>From</b> |
| * header in outgoing requests. |
| * |
| * PJSUA-API supports creating and managing multiple accounts. The maximum |
| * number of accounts is limited by a compile time constant |
| * <tt>PJSUA_MAX_ACC</tt>. |
| * |
| * Account may or may not have client registration associated with it. |
| * An account is also associated with <b>route set</b> and some <b>authentication |
| * credentials</b>, which are used when sending SIP request messages using the |
| * account. An account also has presence's <b>online status</b>, which |
| * will be reported to remote peer when they subscribe to the account's |
| * presence, or which is published to a presence server if presence |
| * publication is enabled for the account. |
| * |
| * At least one account MUST be created in the application. If no user |
| * association is required, application can create a userless account by |
| * calling #pjsua_acc_add_local(). A userless account identifies local endpoint |
| * instead of a particular user, and it correspond with a particular |
| * transport instance. |
| * |
| * Also one account must be set as the <b>default account</b>, which is used as |
| * the account to use when PJSUA fails to match a request with any other |
| * accounts. |
| * |
| * When sending outgoing SIP requests (such as making calls or sending |
| * instant messages), normally PJSUA requires the application to specify |
| * which account to use for the request. If no account is specified, |
| * PJSUA may be able to select the account by matching the destination |

| * @ingroup PJSUA_LIB |
| * @brief Media manipulation. |
| * @{ |
| * |
| * PJSUA has rather powerful media features, which are built around the |
| * PJMEDIA conference bridge. Basically, all media "ports" (such as calls, WAV |
| * players, WAV playlist, file recorders, sound device, tone generators, etc) |
| * are terminated in the conference bridge, and application can manipulate |
| * the interconnection between these terminations freely. |
| * |
| * The conference bridge provides powerful switching and mixing functionality |
| * for application. With the conference bridge, each conference slot (e.g. |
| * a call) can transmit to multiple destinations, and one destination can |
| * receive from multiple sources. If more than one media terminations are |
| * terminated in the same slot, the conference bridge will mix the signal |
| * automatically. |
| * |
| * Application connects one media termination/slot to another by calling |
| * #pjsua_conf_connect() function. This will establish <b>unidirectional</b> |
| * media flow from the source termination to the sink termination. To |
| * establish bidirectional media flow, application wound need to make another |
| * call to #pjsua_conf_connect(), this time inverting the source and |
| * destination slots in the parameter. |
| * |
| * For example, to stream a WAV file to remote call, application may use |
| * the following steps: |
| * |
| \code |
| |
| pj_status_t stream_to_call( pjsua_call_id call_id ) |
| { |
| pjsua_player_id player_id; |
| |
| status = pjsua_player_create("mysong.wav", 0, &player_id); |
| if (status != PJ_SUCCESS) |
| return status; |
| |
| status = pjsua_conf_connect( pjsua_player_get_conf_port(), |
| pjsua_call_get_conf_port() ); |
| } |
| \endcode |
| * |
| * |
| * Other features of PJSUA media: |
| * - efficient N to M interconnections between media terminations. |
| * - media termination can be connected to itself to create loopback |
| * media. |
| * - the media termination may have different clock rates, and resampling |
| * will be done automatically by conference bridge. |
| * - media terminations may also have different frame time; the |
| * conference bridge will perform the necessary bufferring to adjust |
| * the difference between terminations. |
| * - interconnections are removed automatically when media termination |
| * is removed from the bridge. |
| * - sound device may be changed even when there are active media |
| * interconnections. |
| * - correctly report call's media quality (in #pjsua_call_dump()) from |
| * RTCP packet exchange. |
