Cally Square IVR Blocks
This section explains which are the blocks available in Cally Square.
Todesign your IVR flow drag and drop blocks (ready-to-use applications) in the design area and connect them in a flow:
For each block you add, just double click on it and enter the required fields in the pop up screen to setup the corresponding application:
The blocks are collected in Groups of Applications: in the following sections you can find all available application for each group.
Entry group applications
This group - start, finally and end - manages the begin and the end of a call from an Application point of view.
Start | Description The Start block must be the very first one in each IVR application. The application will not be published without the Start box: it can be used just once for each IVR. Parameters
Exit Arrows This block provides just one arrow out to the next step |
Finally | Description This block is executed when the application loses the voice channel. It should be used for example to write some data on a DB after the call hangup or at the end of each IVR. You can use all the boxes you want after the finally. Of course boxes for audio playing will not have any effect on the customer experience. Parameters
Exit Arrows This block provides just one arrow out to the next step |
End | Description This box needs to be placed at the end of every leaf of the IVR tree. You can put an End box either at the end of each leaf or have a unique End box whom all the leaves connect to. Parameters
Exit Arrows This box does not have exit arrow |
Call management applications
This group of boxes - answer, hangup, internal dial, external dial, queue, voicemail, callback - can be used to manage the begin and the end of a call from a Telephony point of view.

RestAPI | 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.
Parameters
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:
module.exports = function({options_object}){ // custom code const variables = { code output as object }; // it must be an object, not an array return 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 const request = options; var const method = request.method; var const uri = request.uri; const myURL = new URL(uri); var const host = myURL.host; var const hostname = myURL.hostname; var const href = myURL.href; var const pathname = myURL.pathname; // etc... // additional custom code var const variables = { code output as object }; callback(null, variables);return 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$$" } it will be completed like this: { "myvar1":"value1", "myvar2":"value2" } NOTE: All special chars in the returned strings from the script are escaped ( e.g. the slash / character is translated to ', so if you want to avoid that you need to in clude an & symbol before the variable name: e.g. { "myvar1":"$$&key1$$", "myvar2":"$$&key2$$" } Built-in variables We provide the following Asterisk channels variables named
