Detailed Description

The base PJSUA API controls PJSUA creation, initialization, and startup, and also provides various auxiliary functions.

Using PJSUA Library

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.

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.

PJSUA-LIB Initialization (in C)

Sample code to initialize PJSUA in C code:

#include <pjsua-lib/pjsua.h>
#define THIS_FILE __FILE__
static pj_status_t app_init(void)
{
pjsua_config ua_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.
// 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;
}
.
...
}

Other Initialization

After PJSUA is initialized with pjsua_init(), application will normally need/want to perform the following tasks:

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.

C Example for Starting PJSUA

Sample code:

static pj_status_t app_run(void)
{
pj_status_t status;
// Start pjsua
status = pjsua_start();
if (status != PJ_SUCCESS) {
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);
...
}
}

Enumeration Type Documentation

Constant to identify invalid ID for all sorts of IDs.

This enumeration represents pjsua state.

Enumerator
PJSUA_STATE_NULL 

The library has not been initialized.

PJSUA_STATE_CREATED 

After pjsua_create() is called but before pjsua_init() is called.

PJSUA_STATE_INIT 

After pjsua_init() is called but before pjsua_start() is called.

PJSUA_STATE_STARTING 

After pjsua_start() is called but before everything is running.

PJSUA_STATE_RUNNING 

After pjsua_start() is called and before pjsua_destroy() is called.

PJSUA_STATE_CLOSING 

After pjsua_destroy() is called but before the function returns.

Enumeration of media transport state types.

Enumerator
PJSUA_MED_TP_NULL 

Null, this is the state before media transport is created.

PJSUA_MED_TP_CREATING 

Just before media transport is created, which can finish asynchronously later.

PJSUA_MED_TP_IDLE 

Media transport creation is completed, but not initialized yet.

PJSUA_MED_TP_INIT 

Initialized (media_create() has been called).

PJSUA_MED_TP_RUNNING 

Running (media_start() has been called).

PJSUA_MED_TP_DISABLED 

Disabled (transport is initialized, but media is being disabled).

This enumeration specifies the options for custom media transport creation.

Enumerator
PJSUA_MED_TP_CLOSE_MEMBER 

This flag indicates that the media transport must also close its "member" or "child" transport when pjmedia_transport_close() is called. If this flag is not specified, then the media transport must not call pjmedia_transport_close() of its member transport.

This enumeration specifies the contact rewrite method.

Enumerator
PJSUA_CONTACT_REWRITE_UNREGISTER 

The Contact update will be done by sending unregistration to the currently registered Contact, while simultaneously sending new registration (with different Call-ID) for the updated Contact.

PJSUA_CONTACT_REWRITE_NO_UNREG 

The Contact update will be done in a single, current registration session, by removing the current binding (by setting its Contact's expires parameter to zero) and adding a new Contact binding, all done in a single request.

PJSUA_CONTACT_REWRITE_ALWAYS_UPDATE 

The Contact update will be done when receiving any registration final response. If this flag is not specified, contact update will only be done upon receiving 2xx response. This flag MUST be used with PJSUA_CONTACT_REWRITE_UNREGISTER or PJSUA_CONTACT_REWRITE_NO_UNREG above to specify how the Contact update should be performed when receiving 2xx response.

This enumeration specifies the usage of SIP Session Timers extension.

Enumerator
PJSUA_SIP_TIMER_INACTIVE 

When this flag is specified, Session Timers will not be used in any session, except it is explicitly required in the remote request.

PJSUA_SIP_TIMER_OPTIONAL 

When this flag is specified, Session Timers will be used in all sessions whenever remote supports and uses it.

PJSUA_SIP_TIMER_REQUIRED 

When this flag is specified, Session Timers support will be a requirement for the remote to be able to establish a session.

PJSUA_SIP_TIMER_ALWAYS 

When this flag is specified, Session Timers will always be used in all sessions, regardless whether remote supports/uses it or not.

This constants controls the use of 100rel extension.

Enumerator
PJSUA_100REL_NOT_USED 

Not used. For UAC, support for 100rel will be indicated in Supported header so that peer can opt to use it if it wants to. As UAS, this option will NOT cause 100rel to be used even if UAC indicates that it supports this feature.

PJSUA_100REL_MANDATORY 

Mandatory. UAC will place 100rel in Require header, and UAS will reject incoming calls unless it has 100rel in Supported header.

PJSUA_100REL_OPTIONAL 

Optional. Similar to PJSUA_100REL_NOT_USED, except that as UAS, this option will cause 100rel to be used if UAC indicates that it supports it.

Flags to be given to pjsua_destroy2()

Enumerator
PJSUA_DESTROY_NO_RX_MSG 

Allow sending outgoing messages (such as unregistration, event unpublication, BYEs, unsubscription, etc.), but do not wait for responses. This is useful to perform "best effort" clean up without delaying the shutdown process waiting for responses.

PJSUA_DESTROY_NO_TX_MSG 

If this flag is set, do not send any outgoing messages at all. This flag is useful if application knows that the network which the messages are to be sent on is currently down.

PJSUA_DESTROY_NO_NETWORK 

Do not send or receive messages during destroy. This flag is shorthand for PJSUA_DESTROY_NO_RX_MSG + PJSUA_DESTROY_NO_TX_MSG.

init_sizeInitial size of the pool.
incrementIncrement size.
Returns
The pool, or NULL when there's no memory.
pj_status_t pjsua_reconfigure_logging ( const pjsua_logging_config c)

pj_status_t pjsua_detect_nat_type ( void  )

This is a utility function to detect NAT type in front of this endpoint. Once invoked successfully, this function will complete asynchronously and report the result in on_nat_detect() callback of pjsua_callback.

After NAT has been detected and the callback is called, application can get the detected NAT type by calling pjsua_get_nat_type(). Application can also perform NAT detection by calling pjsua_detect_nat_type() again at later time.

Note that STUN must be enabled to run this function successfully.

Returns
PJ_SUCCESS on success, or the appropriate error code.
pj_status_t pjsua_get_nat_type ( pj_stun_nat_type type)

Get the NAT type as detected by pjsua_detect_nat_type() function. This function will only return useful NAT type after pjsua_detect_nat_type() has completed successfully and on_nat_detect() callback has been called.

Parameters
typeNAT type.
Returns
When detection is in progress, this function will return PJ_EPENDING and type will be set to PJ_STUN_NAT_TYPE_UNKNOWN. After NAT type has been detected successfully, this function will return PJ_SUCCESS and type will be set to the correct value. Other return values indicate error and type will be set to PJ_STUN_NAT_TYPE_ERR_UNKNOWN.
