| 65 | * @section pjsua_api_intro A SIP User Agent API for C/C++ |
| 66 | * |
| 67 | * PJSUA API is very high level API for constructing SIP multimedia user agent |
| 68 | * applications. It wraps together the signaling and media functionalities |
| 69 | * into an easy to use call API, provides account management, buddy |
| 70 | * management, presence, instant messaging, along with multimedia |
| 71 | * features such as conferencing, file streaming, local playback, |
| 72 | * voice recording, and so on. |
| 73 | * |
| 74 | * @subsection pjsua_for_c_cpp C/C++ Binding |
| 75 | * Application must link with <b>pjsua-lib</b> to use this API. In addition, |
| 76 | * this library depends on the following libraries: |
| 77 | * - <b>pjsip-ua</b>, |
| 78 | * - <b>pjsip-simple</b>, |
| 79 | * - <b>pjsip-core</b>, |
| 80 | * - <b>pjmedia</b>, |
| 81 | * - <b>pjmedia-codec</b>, |
| 82 | * - <b>pjlib-util</b>, and |
| 83 | * - <b>pjlib</b>, |
| 84 | * |
| 85 | * so application must also link with these libraries as well. For more |
| 86 | * information, please refer to |
| 87 | * <A HREF="http://www.pjsip.org/using.htm">Getting Started with PJSIP</A> |
| 88 | * page. |

| 128 | * @subsection creating_pjsua_lib Creating PJSUA |
| 129 | * |
| 130 | * Before anything else, application must create PJSUA by calling |
| 131 | * #pjsua_create(). |
| 132 | * This, among other things, will initialize PJLIB, which is crucial before |
| 133 | * any PJLIB functions can be called, PJLIB-UTIL, and create a SIP endpoint. |
| 134 | * |
| 135 | * After this function is called, application can create a memory pool (with |
| 136 | * #pjsua_pool_create()) and read configurations from command line or file to |
| 137 | * build the settings to initialize PJSUA below. |
| 138 | * |
| 139 | * @subsection init_pjsua_lib Initializing PJSUA |
| 140 | * |
| 141 | * After PJSUA is created, application can initialize PJSUA by calling |
| 142 | * #pjsua_init(). This function takes several optional configuration settings |
| 143 | * in the argument, if application wants to set them. |
| 144 | * |
| 145 | * @subsubsection init_pjsua_lib_c_cpp PJSUA-LIB Initialization (in C) |
| 146 | * Sample code to initialize PJSUA in C code: |
| 147 | \code |
| 148 | |
| 149 | #include <pjsua-lib/pjsua.h> |
| 150 | |
| 151 | #define THIS_FILE __FILE__ |

| 195 | |
| 196 | * @subsection other_init_pjsua_lib Other Initialization |
| 197 | * |
| 198 | * After PJSUA is initialized with #pjsua_init(), application will normally |
| 199 | * need/want to perform the following tasks: |
| 200 | * |
| 201 | * - create SIP transport with #pjsua_transport_create(). Application would |
| 202 | * to call #pjsua_transport_create() for each transport types that it |
| 203 | * wants to support (for example, UDP, TCP, and TLS). Please see |
| 204 | * @ref PJSUA_LIB_TRANSPORT section for more info. |
| 205 | * - create one or more SIP accounts with #pjsua_acc_add() or |
| 206 | * #pjsua_acc_add_local(). The SIP account is used for registering with |
| 207 | * the SIP server, if any. Please see @ref PJSUA_LIB_ACC for more info. |
| 208 | * - add one or more buddies with #pjsua_buddy_add(). Please see |
| 209 | * @ref PJSUA_LIB_BUDDY section for more info. |
| 210 | * - optionally configure the sound device, codec settings, and other |
| 211 | * media settings. Please see @ref PJSUA_LIB_MEDIA for more info. |
| 212 | * |
| 213 | * |
| 214 | * @subsection starting_pjsua_lib Starting PJSUA |
| 215 | * |
| 216 | * After all initializations have been done, application must call |
| 217 | * #pjsua_start() to start PJSUA. This function will check that all settings |
| 218 | * have been properly configured, and apply default settings when they haven't, |
| 219 | * or report error status when it is unable to recover from missing settings. |
| 220 | * |
| 221 | * Most settings can be changed during run-time. For example, application |
| 222 | * may add, modify, or delete accounts, buddies, or change media settings |
| 223 | * during run-time. |

| 2425 | * @{ |
| 2426 | * |
| 2427 | * PJSUA accounts provide identity (or identities) of the user who is currently |
| 2428 | * using the application. In SIP terms, the identity is used as the <b>From</b> |
| 2429 | * header in outgoing requests. |
| 2430 | * |
| 2431 | * PJSUA-API supports creating and managing multiple accounts. The maximum |
| 2432 | * number of accounts is limited by a compile time constant |
| 2433 | * <tt>PJSUA_MAX_ACC</tt>. |
| 2434 | * |
| 2435 | * Account may or may not have client registration associated with it. |
| 2436 | * An account is also associated with <b>route set</b> and some <b>authentication |
| 2437 | * credentials</b>, which are used when sending SIP request messages using the |
| 2438 | * account. An account also has presence's <b>online status</b>, which |
| 2439 | * will be reported to remote peer when they subscribe to the account's |
| 2440 | * presence, or which is published to a presence server if presence |
| 2441 | * publication is enabled for the account. |
| 2442 | * |
| 2443 | * At least one account MUST be created in the application. If no user |
| 2444 | * association is required, application can create a userless account by |
| 2445 | * calling #pjsua_acc_add_local(). A userless account identifies local endpoint |
| 2446 | * instead of a particular user, and it correspond with a particular |
| 2447 | * transport instance. |
| 2448 | * |
| 2449 | * Also one account must be set as the <b>default account</b>, which is used as |
| 2450 | * the account to use when PJSUA fails to match a request with any other |
| 2451 | * accounts. |
| 2452 | * |
| 2453 | * When sending outgoing SIP requests (such as making calls or sending |
| 2454 | * instant messages), normally PJSUA requires the application to specify |
| 2455 | * which account to use for the request. If no account is specified, |
| 2456 | * PJSUA may be able to select the account by matching the destination |
| 2457 | * domain name, and fall back to default account when no match is found. |

| 5276 | * @ingroup PJSUA_LIB |
| 5277 | * @brief Media manipulation. |
| 5278 | * @{ |
| 5279 | * |
| 5280 | * PJSUA has rather powerful media features, which are built around the |
| 5281 | * PJMEDIA conference bridge. Basically, all media "ports" (such as calls, WAV |
| 5282 | * players, WAV playlist, file recorders, sound device, tone generators, etc) |
| 5283 | * are terminated in the conference bridge, and application can manipulate |
| 5284 | * the interconnection between these terminations freely. |
| 5285 | * |
| 5286 | * The conference bridge provides powerful switching and mixing functionality |
| 5287 | * for application. With the conference bridge, each conference slot (e.g. |
| 5288 | * a call) can transmit to multiple destinations, and one destination can |
| 5289 | * receive from multiple sources. If more than one media terminations are |
| 5290 | * terminated in the same slot, the conference bridge will mix the signal |
| 5291 | * automatically. |
| 5292 | * |
| 5293 | * Application connects one media termination/slot to another by calling |
| 5294 | * #pjsua_conf_connect() function. This will establish <b>unidirectional</b> |
| 5295 | * media flow from the source termination to the sink termination. To |
| 5296 | * establish bidirectional media flow, application wound need to make another |
| 5297 | * call to #pjsua_conf_connect(), this time inverting the source and |
| 5298 | * destination slots in the parameter. |
| 5299 | * |
| 5300 | * For example, to stream a WAV file to remote call, application may use |
| 5301 | * the following steps: |
| 5302 | * |
| 5303 | \code |
| 5304 | |
| 5305 | pj_status_t stream_to_call( pjsua_call_id call_id ) |
| 5306 | { |
| 5307 | pjsua_player_id player_id; |
| 5308 | |
| 5309 | status = pjsua_player_create("mysong.wav", 0, &player_id); |
| 5310 | if (status != PJ_SUCCESS) |
| 5311 | return status; |
| 5312 | |
| 5313 | status = pjsua_conf_connect( pjsua_player_get_conf_port(), |
| 5314 | pjsua_call_get_conf_port() ); |
| 5315 | } |
| 5316 | \endcode |
| 5317 | * |
| 5318 | * |
| 5319 | * Other features of PJSUA media: |
| 5320 | * - efficient N to M interconnections between media terminations. |
| 5321 | * - media termination can be connected to itself to create loopback |
| 5322 | * media. |
| 5323 | * - the media termination may have different clock rates, and resampling |
| 5324 | * will be done automatically by conference bridge. |
| 5325 | * - media terminations may also have different frame time; the |
| 5326 | * conference bridge will perform the necessary bufferring to adjust |
| 5327 | * the difference between terminations. |
| 5328 | * - interconnections are removed automatically when media termination |
| 5329 | * is removed from the bridge. |
| 5330 | * - sound device may be changed even when there are active media |
| 5331 | * interconnections. |
| 5332 | * - correctly report call's media quality (in #pjsua_call_dump()) from |
| 5333 | * RTCP packet exchange. |
