IVR Editor PRO
IVR is a new feature introduced in the Helios LTS.
Important
This is an enterprise version feature that is not included in XiVO and is not freely available. To enable it, please contact XiVO team.
It allows to create part of dialplan in a graphical editor.
Installation is described below:
For feature description and users guide see below:
Features
Create a edit part of dialplan (IVR) in graphical editor.
Create caller hangup handler and error handler IVR dialplan branch
Use created IVRs as an incall or a schedule destination
Send call to queue or other defined dialplan object after IVR
Upload and manage IVR specific audio files (voice prompts)
Users’ Guide
IVR management
In menu Services->IPBX in Call management section use option IVR. The page shows list of existing IVRs. Buttons in every IVR line allows you to edit IVR dialplan metadata, edit dialplan and delete dialplan.
Graphical dialplan editor
Dialplan flowchart consists of nodes representing dialplan actions and connections between nodes. Every node type has one entry point (large circle on top of the node rectangle) and this entry point accepts many connection lines. Exceptions are nodes Start, OnHangup and OnError which have no entrypoint. Depending on node type, nodes have zero to many exit points (small circles at bottom of node rectangle). Exit point of node is selected at runtime by result of node action.
In editor you can
Add node to editor pane by clicking on node type in left menu.
Delete node by clicking red cross on node
Set node parameters by clicking pencil on top left node corner anf filling form
Interconnect nodes by dragging exit point of one node to entry point of another or same node
Delete connection line by clicking on rectangle with minus sign on the line
IVR dialplan runtime
IVR dialplan always starts on Start node. This node can be only one in flowchart and cannot be deleted. If caller hangs up in IVR dialplan, call is moved to OnHangup node, if one exists in flowchart. Only one OnHangup node can exists in flowchart. If runtime error happens (nonexistent voice prompt file, wrong expression parameter) call is sent to the OnError node if one exists. Only one OnError node can exist in flowchart.
Variables
Variables in IVR dialplan are NOT the same thing as asterisk dialplan variables. Variables can be set at runtime using assign node or as result of node action. Variable name must start with ‘$’ (dollar sign).
Expressions in node parameters
Node parameters can be constants or expressions. For example node type ‘wait’ has parameter ‘seconds’ which defines time to wait. This parameter can contain
2 constant
= 2 + 2 expression
= 10 + $var expression with variable
String expression can contain string constants in apostrophes or quotes, variables and concatenation operator ‘.’. Numeric expressions can contain integer numbers, variables and operators ‘+’, ‘-’, ‘*’, ‘/’, Logical expressions can contain comparision operators ‘==’, ‘!=’, ‘<’, ‘<=’, ‘>’, ‘<’, ‘>=’ and logical operators ‘!’, ‘&&’, ‘||’.
Expressions in node parameters are evaluated at runtime when node action starts.
Some input fields are listboxes by nature, e.g. voice prompt file is selected from existing files. In such case listbox can be swithced to text input field by clicking to icon next the field label, to allow insert expresion.
E.g. if you have voice prompt files
message-en
message-fr
message-de
you can set variable $lang in dialplan and then expression:
= "message-" . $lang
allows you to use right language variant of message.
Node types
start
Starting node of IVR dialplan. It is created automatically and cannot be deleted. Only one node of type start can exist in flowchart.
Parameters Node has no parameters
Exit points * next
onhangup
This node starts flowchart part which is used after caller hangup, The node has no entry point therefore. Only one node of type onhangup can be present in flowchart.
Parameters
Node has no parameters
Exit points
next
onerror
This node starts flowchart part which is used after runtime error. The node has no entry point therefore. Only one node of type onerror can be present in flowchart.
Parameters
Node has no parameters
Exit points

0: used when condition is evaluated as false
hangup
Hangups the call and exits flowchart AGI script
Parameters
