Callback

Image Removed

Description

The callback block will add the contact in the selected contact manager list. Please remember to associate the list to a queue campaign for Motion Bull to call thecontact at the scheduled time.

Warning

title	Important

A callback scenario is something in which your customers waiting in queue can optionally be diverted to a callback capability. Such capability invites the customer to leave the queue, thus the call center will call him/her back in a lighter traffic period. This feature is mostly used with a queue campaign and it works only if you have the Motion Dialer license

Info
Let's consider that Queue campaign time interval is from 8:00-18:00 and Callback Delay is 30 min. If a customer calls in at 17:40 and decided to be called back, the contact will be scheduled for 18:10. Keep in mind that this is out of the campaign time interval hence Motion Bull will call the contact in the next valid time interval and when there is at least one available agents.

Parameters

Label: here you can type a brief description of the box
Name: Caller name. Default: {CALLERID(name)}
Last Name: Caller last name
Phone: the phone number of the customer that you want to call back. Default: {CALLERID(num)}.
List: contact manager list where the contact will be added.
Delay [min]: time in minutes from NOW (current time) to schedule a contact. Here you can insert a value that defines when the customer will be called.
Priority: add a contact with a specific priority.

Exit Arrows

This box provides just one arrow out to the next step

Image Removed

Description

This is probably one of the most important application box available on Cally Square. Here you can build a complex menu using a single box: you can play the message, count the retries on errors (i.e. to avoid dangerous loops) and set a variable with the digit value(s) pressed by the customers

Parameters

Label: here you can type a brief description
Audio: the name of the audio file you want to play in the current box
Response Timeout: the maximum number of seconds the system waits before considering the customer not interacting with the application
Max Digit: the maximum number of digits the system waits before moving on to the next step
Retries: here you can set the number of loops automatically performed in case of digits not valid or timeout**
Variable: the variable you want to fill with the digits pressed by the customer.

** Please consider the menu box gives the top priority to the invalid (i) or timeout (t) branches (if present) before routing the call in a loop.

# key can be used as an escape digit or as a valid exit key.
If the user doesn't press any keys when the message plays, there is $timeout milliseconds of silence then the command ends.
The user has the opportunity to press a key at any time during the message or the post-message silence. If the user presses a key while the message is playing, the message stops playing. When the first key is pressed a timer starts counting for $timeout milliseconds. Every time the user presses another key the timer is restarted. The command ends when the counter goes to zero or the maximum number of digits is entered, whichever happens first.

Exit Arrows

The menu box lets you draw many exit arrows according to the following syntax:

X: the box waits for one digit if the MaxDigit parameter is set to one
XX: the box waits for exactly N digits (in this example N=2)
i: the system takes this path if the entry selected is invalid
t: the system takes this path if the box goes in case of timeout
-: the system considers this branch when the retry value is reached. Timeout and Invalid branches have higher priority than this branch.

It is possible to add multiple choices for each output branch: use just the comma separated characters.

Say Digits

Image Removed

Description

Here you can play the digits, one by one, in the chosen language (defaults to English)

Exit Arrows
This box provides just one arrow out to the next step

Say Number

Image Removed

Description

Here you can play a number (i.e. 2583 will be played like "two thousand, five hundred and eighty threes")

Parameters

Label: here you can type a brief description

Number: the number you want to be played: they can be both a digit string (i.e. 1234) or a VARIABLE (i.e. {CALLERID(num)})

GetDigits

Image Removed

Description

Here you can prompt the user to insert a series of digits: you can play the message, count the retries on errors (i.e. to avoid dangerous loops) and set a variable with the inserted digits value.
Parameters

Label: here you can type a brief description
Audio: the name of the audio file you want to play in the current box
Response Timeout: the maximum number of seconds the system waits before considering the customer not interacting with the application
Min Digit: the minimum number of digits the system can accept without considering it an invalid entry
Max Digit: the maximum number of digits the system waits before moving on to the next step
Retry: here you can set the number of loops automatically performed in case of invalid digits **
Variable: the variable you want to fill with the digits pressed by the customer.

Info** Please consider that the getdigits box gives the top priority to the invalid (i) branch (if present) before routing the call in a loop.
Pressing the # key has the same effect as the timer running out: the command ends and any previously keyed digits are returned. A side effect of this is that there is no way to read a # key using this command.
If you don't specify $max_digits then the user can enter as many digits as they want.

If the user doesn't press any keys when the message plays, there is $timeout milliseconds of silence then the command ends.
The user has the opportunity to press a key at any time during the message or the post-message silence. If the user presses a key while the message is playing, the message stops playing. When the first key is pressed a timer starts counting for $timeout milliseconds. Every time the user presses another key the timer is reset. The command ends when the counter goes to zero or the maximum number of digits is entered, whichever happens first.Exit Arrows
The getdigits box lets you draw many exit arrows according to the following syntax:

x: is the exit arrow, the path taken when a valid digit is inserted. If not present, on valid entry the call will be dropped.
i: the system takes this path if the entry is invalid. If not present it will simply loop the getdigits box until it runs out of retries.
-: the system takes this path if it runs out of retries. If not present, when the system runs out of retries will simply drop the call.

GetSecretDigits

Image Removed

Description

Hidden Digits Number: the number of digits that the system will hide, for security reasons
Hidden Digits Position: you can set if the First or Last #N digits will be hidden
Variable: the variable you want to fill with the digits pressed by the customer.

Info** Please consider that the getsecretdigits box gives the top priority to the invalid (i) branch (if present) before routing the call in a loop.
Pressing the # key has the same effect as the timer running out: the command ends and any previously keyed digits are returned. A side effect of this is that there is no way to read a # key using this command.
If you don't specify $max_digits then the user can enter as many digits as they want.

If the user doesn't press any keys when the message plays, there is $timeout milliseconds of silence then the command ends.

LumenvoxASR

Image Removed

Description

This box allows you to do a voice-to-text conversion using the Lumenvox ASR application*

Info
*In order to have this box working you must install Lumenvox on a machine that is reachable by your system.

The ASR save the results in three channel variables:

LUMENVOX_ASR_TRANSCRIPT: the result of the dictation recognition

LUMENVOX_ASR_CONFIDENCE: the precision of the recognition, between 0 and 1. Usually values above 0.8-0.9 means that the dictation has been correctly recognised.

LUMENVOX_ASR_INSTANCE: the instance of the recognition.

Parameters

Label: here you can type a brief description
Grammar: The grammar that should be used for the recognition. Grammars can be specified as text/XML inline for built-in grammars or by using a reference to an external file/URI.

If you need to use the multiple grammar, the value of the first grammar must be separated from the second one using a character defined (e.g.: grammar-a%grammar-b, defining the % as a delimiter in the options field gd):

Image Removed

LumenVox provides the following built-in grammars:

URI	Sample Input	Semantic Interpretation Result
builtin:grammar/boolean	"yes", "no thank you", etc.	"true" or "false"
builtin:grammar/date	"january thirteenth" or "december first two thousand"	"????0113" or "20001201"
builtin:grammar/digits	"one two three four"	"1234"
builtin:grammar/currency	"eighteen dollars and four cents"	"USD18.04"
builtin:grammar/number	"four hundred point five"	"400.5"
builtin:grammar/phone	"area code eight five eight seven oh seven oh seven oh seven"	"8587070707"
builtin:grammar/time	"six o clock" or "five thirty p m"	"0600?" or "0530p"

Options:

Options control details about the recognition. Valid options are:

p - Profile to use in mrcp.conf
i - Digits to allow recognition to be interrupted with. Set this to "none" to allow LumenVox to process the DTMF using a DTMF grammar. Otherwise, if "any" or other digits specified, recognition will be interrupted and the digit will be returned to dialplan.
f - Filename to play while recognition occurs (if empty or not specified, no file is played)
t - The recognition timeout (in milliseconds). This is the total amount of time a caller has to speak.
b - Barge-in value (no barge-in=0, ASR engine barge-in=1, Asterisk barge-in=2). LumenVox strongly recommends allowing the ASR to perform barge-in instead of Asterisk.
gd – The grammar delimiter. Defaults to a comma.
ct - The confidence threshold (0.0 - 1.0). If a recognition result has a confidence score below this value, it will be returned as "no match." Defaults to 0.5.
sl - The barge-in sensitivity level (0.0 - 1.0). The higher this number, the easier it is to barge-in. Defaults to 0.5.
sva - Speed vs. accuracy, set on a scale of 0.0 - 1.0. The higher this number, the faster (and less accurate) recognitions will be. Defaults to 0.5.
nb - N-best list length. Defaults to 1; increase this value if you wish to get more answers back from the recognizer.
nit - No input timeout. This is the amount of time the caller has to start speaking before the recognizer returns a no-input result.
sct - Speech Complete Timeout. This is the amount of time, in milliseconds, LumenVox must detect silence after a user stops speaking before the recognizer begins processing the utterance. Set this lower for single word utterances and higher for longer utterances. In most cases, a value of 800 is correct.
dit - DTMF interdigit timeout
dtt - DTMF terminate timout
dttc - DTMF terminate characters
sw - Save Waveform (true/false)
nac - new audio channel (true/false)
spl - speech language (en-US/en-GB/etc.). If a language is declared in a grammar (it should be) this will be ignored.
cdb - clear DTMF buffer (true/false)
mt - media type
iwu - input waveform URI (only applies to MRCPv2). Not supported by LumenVox.
sint - Speech Incomplete Timeout. Not supported by LumenVox.
rm - Recognition Mode. Not supported by LumenVox.
hmaxd - hotword max duration. Not supported by LumenVox.
hmind - hotword min duration. Not supported by LumenVox.

RestAPI

Image Removed

Description

This box allows you to use Restful API to GET, POST, PUT, DELETE data from external applications or sources (for example: ticketing systems, CRM, order systems, and so on). The result of the API request (Body) can also be stored in a Variable.

Info
*Internet connection is required for this box to work

Info

title	About REST API

A RESTful API (REST is an acronym for Representational State Transfer) is an application program interface (API) that uses HTTP requests to GET, PUT, POST and DELETE data: the client requests the server for the required information, via an API, and then, the server sends a response to the client.
The data returned by the server, in response to the request of the client is either in the format of JSON or XML. Both JSON and XML format have a proper hierarchical structure of data. REST is an architectural style as well as an approach for communication purposes that is often used in various web services development (the architectural style of REST helps in leveraging the lesser use of bandwidth to make an application more suitable for the internet).

Parameters

Label: here you can type a brief description
URL: request URL
Method: HTTP method (GET, POST, PUT or DELETE)
Timeout: request timeout (in seconds: it must be greater than 1 and the default value is 5)
Computed Variables Script Path: absolute path of a NodeJS script able to compute variables to pass in the URL, Headers and Bod
Headers: request headers (it must be in RAW JSON format, i.e. {"key": "value"})
Body: request body (it must be in RAW JSON format, i.e. {"key": "value"})
Variable: here you can choose a variable from a pick up list where you want to store the body of the response. The system will parse the body of the response and it will create a variable for each key-value pair using the format variable name + <key> (e.g. variablename.key, variablename.index.key or variablename.key[0].subkey if key is an array, and so on)

Custom script guidelines

You can valorize custom variables to use in you request using a nodejs script located on your server.

You can insert the absolute path to the script inside the Computed Variables Script Path input.

Remember to follow these important rules:

insert the absolute path to the file
write the path without quotes
the motion user must have both read and write and execution privileges on the js file (or it won't work at all once it is required).
The js script must be written in javascript ECMA5, and follow the NodeJs 6.x framework syntax based on this template:

module.exports = function({options_object}, callback){

// custom code

var variables = { code output as object }; // it must be an object, not an array

callback(null, variables);

}

The script also receives the options you inserted in the restAPI block, including URL and method, so you can use them in the script if needed.

e.g.

const { URL } = require('url');

module.exports = function(options, callback){

var request = options;

var method = request.method;

var uri = request.uri;

const myURL = new URL(uri);

var host = myURL.host;

var hostname = myURL.hostname;

var href = myURL.href;

var pathname = myURL.pathname;

// etc...

// additional custom code

var variables = { code output as object };

callback(null, variables);

}

Variables and custom (script) variables

To include asterisk variables in your URL, you must include them in curly brackets.

e.g.

https://myurl.com?phone={CALLERID(num)}

The same apply if you want to include them in the body of your request, or in your headers ( pay attention to the quotes "").

e.g.

{

"phone":"{CALLERID(num)}"

}

To include custom (script) variables, you must include them in double dollar $$ symbols.

e.g.

Your script returns an object like this:

{

key1: "value1",

key2: "value2"

}

To use them in your URL you can write:

https://myurl.com?myvar1=$$key1$$&myvar2=$$key2$$

and it will be completed like this:

https://myurl.com?myvar1=value1&myvar2=value2

The same apply if you want to include them in the body of your request, or in your headers ( pay attention to the quotes "").

So, if your body/header object is written like this:

{

"myvar1":"$$key1$$",

"myvar2":"$$key2$$"

}

it will be completed like this:

{

"myvar1":"value1",

"myvar2":"value2"

}

NOTE: All special chars in the returned strings from the script are escaped ( e.g. the slash / character is translated to &#x27, so if you want to avoid that you need to in clude an & symbol before the variable name:

e.g.

{

"myvar1":"$$&key1$$",

"myvar2":"$$&key2$$"

}

Built-in variables

We provide the following Asterisk channels variables named

variable name + _STATUS_CODE: shows the HTTP request status code
variable name + _STATUS_MESSAGE: shows the HTTP request status message

Example: RESULT_STATUS_CODE
