PJSIP_EPENDINGTX

Buffer is being sent, operation still pending.

PJSIP_ERXOVERFLOW

Rx buffer overflow. See also PJSIP_EMSGTOOLONG.

PJSIP_EBUFDESTROYED

This is not really an error, it just informs application that transmit data has been deleted on return of pjsip_tx_data_dec_ref().

PJSIP_ETPNOTSUITABLE

Unsuitable transport selected. This error occurs when application has explicitly requested to use a particular transport/listener, but the selected transport is not suitable to send request to the specified destination.

PJSIP_ETPNOTAVAIL

Transport not available. This error occurs for example when the SIP stack is trying to use a SIP transport while the transport is being paused by application.

PJSIP_ETSXDESTROYED

Transaction has just been destroyed.

PJSIP_EFAILEDCREDENTIAL

Credential failed to authenticate. For this failure, right credential for the realm has been found and used to authenticate against the challenge, but the server has rejected the authorization request with 401/407 response (either with no stale parameter or with “stale=false” parameter). In most cases, this indicates that the username/password combination is incorrect.

PJSIP_ENOCREDENTIAL

No suitable credential is found to authenticate the request against the received authentication challenge in 401/407 response. This often is caused by different realm supplied in the credential than the realm found in the challenge.

Functions

pj_str_t pjsip_strerror(pj_status_t status, char *buffer, pj_size_t bufsize)

Get error message for the specified error code. Note that this function is only able to decode PJSIP specific error code. Application should use pj_strerror(), which should be able to decode all error codes belonging to all subsystems (e.g. pjlib, pjmedia, pjsip, etc).

Parameters:

• status – The error code.

• buffer – The buffer where to put the error message.

• bufsize – Size of the buffer.

Returns:

The error message as NULL terminated string, wrapped with pj_str_t.
