◆ ast_start_mixmonitor()

int ast_start_mixmonitor	(	struct ast_channel *	chan,
		const char *	filename,
		const char *	options
	)

Start a mixmonitor on a channel with the given parameters.

Since: 12.0.0

Parameters

chan	Which channel to apply the MixMonitor to
filename	filename to use for the recording
options	Optional arguments to be interpreted by the MixMonitor start function

Return values

0	if successful
non-zero	on failure

Note: This function will always fail is nothing has set the mixmonitor methods

◆ ast_stop_mixmonitor()

int ast_stop_mixmonitor	(	struct ast_channel *	chan,
		const char *	mixmon_id
	)

Stop a mixmonitor on a channel with the given parameters.

Since: 12.0.0

Parameters

chan	Which channel to stop a MixMonitor on (may be NULL if mixmon_id is provided)
mixmon_id	Which mixmon_id should be stopped (may be NULL if chan is provided)

Return values

0	if successful
non-zero	on failure
