group PJSUA_LIB_ACC

PJSUA Accounts management.

PJSUA accounts provide identity (or identities) of the user who is currently using the application. In SIP terms, the identity is used as the From header in outgoing requests.

PJSUA-API supports creating and managing multiple accounts. The maximum number of accounts is limited by a compile time constant PJSUA_MAX_ACC.

Account may or may not have client registration associated with it. An account is also associated with route set and some authentication credentials, which are used when sending SIP request messages using the account. An account also has presence’s online status, 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 default account, 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 domain name, and fall back to default account when no match is found.

Defines

PJSUA_MAX_ACC

Maximum accounts.

PJSUA_REG_INTERVAL

Default registration interval.

PJSUA_UNREG_TIMEOUT

Default maximum time to wait for account unregistration transactions to complete during library shutdown sequence.

Default: 4000 (4 seconds)

PJSUA_PUBLISH_EXPIRATION

Default PUBLISH expiration

PJSUA_DEFAULT_ACC_PRIORITY

Default account priority.

PJSUA_SECURE_SCHEME

This macro specifies the URI scheme to use in Contact header when secure transport such as TLS is used. Application can specify either “sip” or “sips”.

PJSUA_UNPUBLISH_MAX_WAIT_TIME_MSEC

Maximum time to wait for unpublication transaction(s) to complete during shutdown process, before sending unregistration. The library tries to wait for the unpublication (un-PUBLISH) to complete before sending REGISTER request to unregister the account, during library shutdown process. If the value is set too short, it is possible that the unregistration is sent before unpublication completes, causing unpublication request to fail.

Default: 2000 (2 seconds)

PJSUA_REG_RETRY_INTERVAL

Default auto retry re-registration interval, in seconds. Set to 0 to disable this. Application can set the timer on per account basis by setting the pjsua_acc_config.reg_retry_interval field instead.

Default: 300 (5 minutes)

PJSUA_CONTACT_REWRITE_METHOD

This macro specifies the default value for contact_rewrite_method field in pjsua_acc_config. I specifies how Contact update will be done with the registration, if allow_contact_rewrite is enabled in the account config.

If set to 1, 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.

If set to 2, 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.

Value 1 is the legacy behavior.

Default value: 2

PJSUA_REG_USE_OUTBOUND_PROXY

Bit value used in pjsua_acc_config.reg_use_proxy field to indicate that the global outbound proxy list should be added to the REGISTER request.

PJSUA_REG_USE_ACC_PROXY

Bit value used in pjsua_acc_config.reg_use_proxy field to indicate that the account proxy list should be added to the REGISTER request.

PJSUA_CALL_HOLD_TYPE_DEFAULT

Specify the default call hold type to be used in pjsua_acc_config.

Default is PJSUA_CALL_HOLD_TYPE_RFC3264, and there’s no reason to change this except if you’re communicating with an old/non-standard peer.

Enums

enum pjsua_call_hold_type

This enumeration specifies how we should offer call hold request to remote peer. The default value is set by compile time constant PJSUA_CALL_HOLD_TYPE_DEFAULT, and application may control the setting on per-account basis by manipulating call_hold_type field in pjsua_acc_config.

Values:

enumerator PJSUA_CALL_HOLD_TYPE_RFC3264

This will follow RFC 3264 recommendation to use a=sendonly, a=recvonly, and a=inactive attribute as means to signal call hold status. This is the correct value to use.

enumerator PJSUA_CALL_HOLD_TYPE_RFC2543

This will use the old and deprecated method as specified in RFC 2543, and will offer c=0.0.0.0 in the SDP instead. Using this has many drawbacks such as inability to keep the media transport alive while the call is being put on hold, and should only be used if remote does not understand RFC 3264 style call hold offer.

Functions

Call this function to initialize account config with default values.

Parameters

cfg – The account config to be initialized.

Parameters

acc_id – Account ID to check.

Returns

Non-zero if account ID is valid.

pj_status_t pjsua_acc_set_default(pjsua_acc_id acc_id)

Set default account to be used when incoming and outgoing requests doesn’t match any accounts.

pj_status_t pjsua_acc_add(const pjsua_acc_config *acc_cfg, pj_bool_t is_default, pjsua_acc_id *p_acc_id)

Add a new account to pjsua. PJSUA must have been initialized (with pjsua_init()) before calling this function. If registration is configured for this account, this function would also start the SIP registration session with the SIP registrar server. This SIP registration session will be maintained internally by the library, and application doesn’t need to do anything to maintain the registration session.

Parameters

  • acc_cfg – Account configuration.

  • is_default – If non-zero, this account will be set as the default account. The default account will be used when sending outgoing requests (e.g. making call) when no account is specified, and when receiving incoming requests when the request does not match any accounts. It is recommended that default account is set to local/LAN account.

  • p_acc_id – Pointer to receive account ID of the new account.

Returns

PJ_SUCCESS on success, or the appropriate error code.

pj_status_t pjsua_acc_add_local(pjsua_transport_id tid, pj_bool_t is_default, pjsua_acc_id *p_acc_id)

Add a local account. A local account is used to identify local endpoint instead of a specific user, and for this reason, a transport ID is needed to obtain the local address information.

Parameters

  • tid – Transport ID to generate account address.

  • is_default – If non-zero, this account will be set as the default account. The default account will be used when sending outgoing requests (e.g. making call) when no account is specified, and when receiving incoming requests when the request does not match any accounts. It is recommended that default account is set to local/LAN account.

  • p_acc_id – Pointer to receive account ID of the new account.
