SIP_ENABLE_TRANS_LOGGING 3SIP "November 22, 2021"
NAME
sip_enable_trans_logging, sip_enable_dialog_logging,
sip_disable_dialog_logging, sip_disable_trans_logging - transaction and dialog
logging operations
SYNOPSIS
cc [ flag... ] file... -lsip [ library... ] #include <sip.h> int sip_enable_trans_logging(FILE *logfile, int flags);
int sip_enable_dialog_logging(FILE *logfile, int flags);
void sip_disable_dialog_logging();
void sip_disable_trans_logging();
DESCRIPTION
The sip_enable_trans_logging() and sip_enable_dialog_logging()
functions enable transaction and dialog logging respectively. The logfile
argument points to a file to which the SIP messages are logged. The flags
argument controls the amount of logging. The only flag defined in <sip.h>
is SIP_DETAIL_LOGGING. Either transaction or dialog logging, or both, can
be enabled at any time. For dialog logging to work, the SIP stack must be
enabled to manage dialogs (using SIP_STACK_DIALOGS, see
sip_stack_init(3SIP)) when the stack is initialized.
All the messages exchanged within a transaction/dialog is captured and later dumped to a log file when the transaction or dialog is deleted or terminated. Upon termination, each dialog writes to the file the messages that were processed in its context. Similarly, upon termination each transaction writes to the file the messages that were processed in its context.
The sip_disable_trans_logging() and sip_disable_dialog_logging() functions disable the transaction or dialog logging. These functions do not close the files. It is the responsibility of the application to close them.
The log contains the state of the transaction or dialog at the time the message was processed.
RETURN VALUES
Upon successful completion, sip_enable_trans_logging() and
sip_enable_dialog_logging() return 0. They return EINVAL if
logfile is NULL or flags is unrecognized.
EXAMPLES
Example 1 Dialog logging
The following is an example of dialog logging.
FILE *logfile;
logfile = fopen("/tmp/ApplicationA", "a+");
sip_enable_dialog_logging(logfile, SIP_DETAIL_LOGGING);
/* Application sends INVITE, receives 180 and 200 response and dialog is
created. */
/* Application sends ACK request */
/* Application sends BYE and receives 200 response */
/* Application disables logging */
sip_disable_dialog_logging();
The log file will be of the following format.
