Function Documentation

static int __ast_play_and_record ( struct ast_channel chan,
const char *  playfile,
const char *  recordfile,
int  maxtime,
const char *  fmt,
int *  duration,
int  beep,
int  silencethreshold,
int  maxsilence,
const char *  path,
int  prepend,
const char *  acceptdtmf,
const char *  canceldtmf 
) [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 milliseconds).
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).
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.
acceptdtmf DTMF digits that will end the recording.
canceldtmf DTMF digits that will cancel the recording.

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.

int ast_app_getdata ( struct ast_channel c,

Plays a stream and gets DTMF data from a channel.

Parameters:
c The channel to read from
prompt The file to stream to the channel
s The string to read in to. Must be at least the size of your length
maxlen How many digits to read (maximum)
timeout set timeout to 0 for "standard" timeouts. Set timeout to -1 for "ludicrous time" (essentially never times out)

unsigned int ast_app_separate_args ( char *  buf,
char  delim,
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
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.

int ast_dtmf_stream ( struct ast_channel chan,
struct ast_channel peer,
const char *  digits,
int  between 
)

Send DTMF to a channel.

Parameters:
chan The channel that will receive the DTMF frames
peer (optional) Peer channel that will be autoserviced while the primary channel is receiving DTMF
digits This is a string of characters representing the DTMF 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' to add a 500 millisecond pause to the DTMF sequence.
between This is the number of milliseconds to wait in between each DTMF digit. If zero milliseconds is specified, then the default value of 100 will be used.
