Wait for specified number of DTMF digits, untile terminator is received or until the channel hangs up.

Parameters

session	the session to read.
buf	strig to write to
buflen	max size of buf
maxdigits	max number of digits to read
terminators	digits to end the collection
terminator	actual digit that caused the collection to end (if any)
first_timeout	timeout in ms
digit_timeout	digit timeout in ms
abs_timeout	abs timeout in ms

Returns

SWITCH_STATUS_SUCCESS to keep the collection moving.

	)

Initialize background Speech detection on a session, so that parameters can be set, and grammars loaded. After calling this function, it is possible to call switch_ivr_set_param_detect_speech() to set recognition parameters. Calling switch_ivr_detect_speech_load_grammar() starts the speech recognition.

Parameters

session	the session to attach
mod_name	the module name of the ASR library
dest	the destination address
ah	an ASR handle to use (NULL to create one)

Returns

Make an outgoing call.

Parameters

session	originating session
bleg	B leg session
cause	a pointer to hold call cause
bridgeto	the desired remote callstring
timelimit_sec	timeout in seconds for outgoing call
table	optional state handler table to install on the channel
cid_name_override	override the caller id name
cid_num_override	override the caller id number
caller_profile_override	override the entire calling caller profile
ovars	variables to be set on the outgoing channel
flags	flags to pass

Returns

SWITCH_STATUS_SUCCESS if bleg is a running session.

Note

bleg will be read locked which must be unlocked with switch_core_session_rwunlock() before losing scope

	)

Play a sound and gather digits with the number of retries specified if the user doesn't give digits in the set time.

Parameters

session	the current session to play sound to and collect digits
min_digits	the fewest digits allowed for the response to be valid
max_digits	the max number of digits to accept
max_tries	number of times to replay the sound and capture digits
timeout	time to wait for input (this is per iteration, so total possible time = max_tries * (timeout + audio playback length)
valid_terminators	for input that can include # or * (useful for variable length prompts)
audio_file	file to play
bad_input_audio_file	file to play if the input from the user was invalid
var_name	variable name to put results in
digit_buffer	variable digits captured will be put back into (empty if capture failed)
digit_buffer_length	length of the buffer for digits (should be the same or larger than max_digits)
digits_regex	the qualifying regex

Returns

switch status, used to note status of channel (will still return success if digit capture failed)

Note

to test for digit capture failure look for \0 in the first position of the buffer
