Function Documentation

__ast_app_separate_args()

unsigned int __ast_app_separate_args	(	char *	buf,
		char	delim,
		int	remove_chars,
		char **	array,
		int	arraylen
	)

Separate a string into arguments in an array.

Parameters

buf	The string to be parsed (this must be a writable copy, as it will be modified)
delim	The character to be used to delimit arguments
remove_chars	Remove backslashes and quote characters, while parsing
array	An array of 'char *' to be filled in with pointers to the found arguments
arraylen	The number of elements in the array (i.e. the number of arguments you will accept)

Note: if there are more arguments in the string than the array will hold, the last element of the array will contain the remaining arguments, not separated.

The array will be completely zeroed by this function before it populates any entries.

Returns

The number of arguments found, or zero if the function arguments are not valid.

__ast_play_and_record()

static int __ast_play_and_record ( struct ast_channel *  chan, const char *  playfile, const char *  recordfile, int  maxtime, const char *  fmt, int *  duration, int *  sound_duration, int  beep, int  silencethreshold, int  maxsilence, const char *  path, int  prepend, const char *  acceptdtmf, const char *  canceldtmf, int  skip_confirmation_sound, enum ast_record_if_exists  if_exists  )

static

Optionally play a sound file or a beep, then record audio and video from the channel.

Parameters

chan	Channel to playback to/record from.
playfile	Filename of sound to play before recording begins.
recordfile	Filename to record to.
maxtime	Maximum length of recording (in seconds).
fmt	Format(s) to record message in. Multiple formats may be specified by separating them with a '|'.
duration	Where to store actual length of the recorded message (in milliseconds).
sound_duration	Where to store the length of the recorded message (in milliseconds), minus any silence
beep	Whether to play a beep before starting to record.
silencethreshold
maxsilence	Length of silence that will end a recording (in milliseconds).
path	Optional filesystem path to unlock.
prepend	If true, prepend the recorded audio to an existing file and follow prepend mode recording rules
acceptdtmf	DTMF digits that will end the recording.
canceldtmf	DTMF digits that will cancel the recording.
skip_confirmation_sound	If true, don't play auth-thankyou at end. Nice for custom recording prompts in apps.

Return values

-1	failure or hangup
'S'	Recording ended from silence timeout
't'	Recording ended from the message exceeding the maximum duration, or via DTMF in prepend mode
dtmfchar	Recording ended via the return value's DTMF character for either cancel or accept.

Note

Instead of asking how much time passed (end - start), calculate the number of seconds of audio which actually went into the file. This fixes a problem where audio is stopped up on the network and never gets to us.

Note that we still want to use the number of seconds passed for the max message, otherwise we could get a situation where this stream is never closed (which would create a resource leak).

Note

If we ended with silence, trim all but the first 200ms of silence off the recording. However, if we ended with '#', we don't want to trim ANY part of the recording.

Same logic as above.

ast_app_exec_macro()

int ast_app_exec_macro	(	struct ast_channel *	autoservice_chan,

Run a macro on a channel, placing an optional second channel into autoservice.

Since

11.0

This is a shorthand method that makes it very easy to run a macro on any given channel. It is perfectly reasonable to supply a NULL autoservice_chan here in case there is no channel to place into autoservice.

Note

Absolutely NO channel locks should be held before calling this function.

Parameters

autoservice_chan	A channel to place into autoservice while the macro is run
macro_chan	Channel to execute macro on.
macro_args	Macro application argument string.

Return values

0	success
-1	on error

11

This is a shorthand method that makes it very easy to run a subroutine on any given channel. It is perfectly reasonable to supply a NULL autoservice_chan here in case there is no channel to place into autoservice.

Note

Absolutely NO channel locks should be held before calling this function.

Parameters

autoservice_chan	A channel to place into autoservice while the subroutine is run
sub_chan	Channel to execute subroutine on.
sub_args	Gosub application argument string.
ignore_hangup	TRUE if a hangup does not stop execution of the routine.

Return values

0	success
-1	on error

ast_app_run_sub()

int ast_app_run_sub	(	struct ast_channel *	autoservice_chan,
		struct ast_channel *	sub_chan,
		const char *	sub_location,
		const char *	sub_args,
		int	ignore_hangup
	)

Run a subroutine on a channel, placing an optional second channel into autoservice.

Since

11

This is a shorthand method that makes it very easy to run a subroutine on any given channel. It is perfectly reasonable to supply a NULL autoservice_chan here in case there is no channel to place into autoservice.

Note

Absolutely NO channel locks should be held before calling this function.

Parameters

autoservice_chan	A channel to place into autoservice while the subroutine is run
sub_chan	Channel to execute subroutine on.
sub_location	The location of the subroutine to run.
sub_args	The arguments to pass to the subroutine.
ignore_hangup	TRUE if a hangup does not stop execution of the routine.

Return values

0	success
-1	on error

		const char *	digits,
		int	between,
		unsigned int	duration,
		unsigned int	durationkp,
		unsigned int	durationst,
		int	is_external
	)

Send a string of MF digits to a channel.

Parameters

chan	The channel that will receive the MF frames
peer	(optional) Peer channel that will be autoserviced while the primary channel is receiving MF
digits	This is a string of characters representing the MF digits to be sent to the channel. Valid characters are "0123456789*#abcdABCD". Note: You can pass arguments 'f' or 'F', if you want to Flash the channel (if supported by the channel), or 'w' or 'W' to add a wink (if supported by the channel).
between	This is the number of milliseconds to wait in between each MF digit. If zero milliseconds is specified, then the default value of 50 will be used.
duration	This is the duration that each numeric MF digit should have. Default value is 55.
durationkp	This is the duration that each KP digit should have. Default is 120.
durationst	This is the duration that each ST, STP, ST2P, or ST3P digit should have. Default is 65.
is_external	1 if called by a thread that is not the channel's media handler thread, 0 if called by the channel's media handler thread.

Return values

0	on success.
-1	on failure or a channel hung up.

		int	maxsilence_ms
	)

Record a file based on input frm a channel. Recording is performed in 'prepend' mode which works a little differently from normal recordings This function will not play a success message due to post-recording control in the application this was added for.

Parameters

chan	the channel being recorded
playfile	Filename of sound to play before recording begins
recordfile	Filename to save the recording
maxtime_sec	Longest possible message length in seconds
fmt	string containing all formats to be recorded delimited by '|'
duration	pointer to integer for storing length of the recording
sound_duration	pointer to integer for storing length of the recording minus all silence
beep	whether to play a beep to prompt the recording
silencethreshold	tolerance of noise levels that can be considered silence for the purpose of silence timeout, -1 for default
maxsilence_ms	length of time in milliseconds which will trigger a timeout from silence, -1 for default.

Return values

-1	failure or hangup
'S'	Recording ended from silence timeout
't'	Recording either exceeded maximum duration or the call was ended via DTMF
