Supported VoiceXML Elements

You can use only the supported VoiceXML elements and attributes. They are listed in the table below.

Note: If you import a VoiceXML application that includes other than supported elements, they are removed during import. Import does not check if the VoiceXML is logically sound after removing those elements.

The elements callout, connect, customstate, error, setextradata, setlanguage, setobcallresult, setpriority, setrecordingconsent, setskills, soap and timeout are specific to Sinch Contact Pro , they are extensions to the VoiceXML standard. Other elements also have Sinch Contact Pro -specific attributes. Those specific elements and attributes are marked in VoiceXML documents with the prefix bcm:.

Only block, callout, customstate, form, menu, noinput, nomatch, setextradata, setlanguage, setpriority, setrecordingconsent, setskills, soap, and var elements can be placed directly to the VoiceXML document. Others can be child elements to these parent elements, or their child elements, only. All parent and child elements are listed in the table below.

In the table, links in the element names provide more specific information about the element. For general instructions about element attributes, see Element Attributes.

* = The element is specific to Sinch Contact Pro , not part of the VoiceXML standard.

Table 1. Supported VoiceXML Elements
Element	Description	Parent Elements _{VXML refers to main level in VoiceXML document}	Child Elements
assign	Assigns a value to a variable.	block, error, filled, if, noinput, nomatch, timeout	-
audio	Plays audio files in the IVR application.	block, choice, error, field, filled, if, menu, noinput, nomatch, record, timeout, transfer	-
block	A container element for executable content that executes if the condition of the block equals to true.	form, vxml	assign, audio, callout, clear, customstate, disconnect, exit, goto, if, log, prompt, setlanguage, setpriority, setskills, soap, var
callout *	Creates a new call to another destination, joining the original call and the new call together. Call control is returned to the IVR after the new call terminates.	block, filled, form, if, noinput, nomatch, vxml	error, timeout
choice	Defines a menu item.	menu	-
clear	Resets the selected element's value, or if no elements are selected, the fields in the form element it is placed in.	block, error, filled, if, noinput, nomatch, timeout	-
connect *	Connects the call. Used in early queuing IVRs.	block, error, filled, nomatch, timeout	-
customstate *	Calls a Python customizer. To manage customizers in the system, see Managing Customizers for IVRs	block, error, form, if, timeout, vxml	error, timeout
disconnect	Disconnects the call.	block, error, filled, nomatch, timeout	-
else	Is used as the final logic constructor in an array of conditional statements, and its content is executed when all earlier conditional statements evaluate to false.	if	-
elseif	Is used to specify additional content when all other conditional statements in an array of conditional statements evaluate to false. The application will execute the first conditional statement that evaluates to true.	if	-
error *	Is used with the soap and customstateelements. It allows assigning event handlers when a query fails with an error.	callout, customstate, soap	assign, audio, callout, clear, customstate, disconnect, exit, goto, if, log, prompt, setlanguage, setpriority, setskills, soap, var
exit	Exits the IVR application. Note: Make sure the call knows where to go after exiting, for example, in opt-in IVRs it returns to original queue. To finish the call, use the disconnect element.	block, error, filled, if, noinput, nomatch, timeout	-
field	Allows IVR applications to collect information from users.	form	audio, filled, log, noinput, nomatch, prompt
filled	Checks if there is caller input in field or record elements.	form, field, record	assign, audio, callout, clear, disconnect, exit, goto, if, log, prompt, setlanguage, setpriority, setskills, var
form	Acts as a container for all field items, and for all control items.	vxml	block, callout, customstate, field, filled, noinput, nomatch, record, soap, transfer, var
goto	Is used to transfer application execution to a specific element in current VXML document.	block, error, filled, if, noinput, nomatch, timeout	-
if	Specifies conditional statements that allow choosing different options based on, for example, variable values.	block, error, filled, if, noinput, nomatch, timeout	assign, audio, callout, clear, customstate, else, elseif, exit, goto, if, log, prompt, setlanguage, setprioroty, setskills, soap, var
log	Allows writing messages to CEM log.	block, error, field, filled, if, nomatch, timeout	-
menu	Enables building a DTMF controlled menu with a maximum of 12 menu items.	vxml	audio, choice, noinput, nomatch, prompt
noinput	Handles situations when the IVR application expects DTMF input from the caller, but has received none.	field, form, menu, transfer, record, vxml	assign, audio, clear, exit, goto, if
nomatch	Handles situations when the caller inputs a value that is not recognized by the IVR application.	field, form, menu, transfer, vxml	assign, audio, clear, disconnect, exit, goto, if, log, var
prompt	Enables building audio messages that include numerical information, such as cardinal and ordinal numbers, dates, and times. Requires the say-as child element.	block, error, field, filled, if, menu, record, timeout, transfer	say-as
record	Enables the audio recording of the call.	form	audio, filled, noinput, nomatch, prompt
say-as	Spells numerical information as string of numbers, cardinal numbers, ordinal numbers, dates, times, and date-times. Requires the value child element.	prompt	value
setextradata *	Allows attaching extra data to the call. Typically it is used in opt-in IVRs to attach the survey IVR number to the call and thus connect the call to the right survey. Expression can be a Python statement, or a number.	block, error, if, noinput, nomatch, timeout, vxml	-
setlanguage *	Sets the call language, that is, selects one of the supported languages and passes this selection to a queue or application where the call is transferred to. If the call language is not set, the system language is used.	block, error, filled, if, nomatch, noinput, timeout, vxml	-
setobcallresult *	Sets the call result for an Outbound campaign call	block,filled, if, nomatch, noinput	-
setpriority *	Allows setting the call priority expression. Expression can be a Python statement, or a number.	block, error, filled, if, noinput, nomatch, timeout, vxml	-
Setrecordingconsent Element *	Enables saving the customer consent in the database for later use.	block, error, filled, if, noinput, nomatch, timeout, vxml	-
setskills *	Allows setting skill requirements for the call.	block, error, filled, if, noinput, nomatch, timeout, vxml	-
soap *	Is used to fetch data from external data sources by using the SOAP protocol.	block, error, form, if, timeout, vxml	error, timeout
timeout *	Is used with the soap and customstate elements. It allows assigning event handlers when a SOAP query times out.	callout, customstate, soap	assign, audio, callout, clear, customstate, disconnect, exit, goto, if, log, prompt, setlanguage, setpriority, setskills, soap, var
transfer	Transfers caller to another destination, such as a queue, or another IVR application.	form	audio, filled, noinput, nomatch, prompt
value	Defines the numerical value used in the say-as element.	say-as	-
var	Sets a VoiceXML variable within the scope specified by its parent element.	block, error, filled, form, if, nomatch, timeout, vxml	-
