The Subdialog_Start element should be placed at the entrance point of any application after the Call Start element, unless the 
application is designed to be invoked by a Cisco CVP VoiceXML Application to Application transfer element.  This element is used 
to take data passed from the calling subdialog and create corresponding element or session data.  Data can be passed from the calling 
subdialog to the application as HTTP parameters and/or as VoiceXML parameters (using the <param> tag).  If data from the calling 
subdialog is passed as HTTP parameters, CVP VoiceXML Server will automatically create session data using the name of the data 
that is sent.  However, if data is passed using VoiceXML parameters, the Subdialog_Start element must be configured appropriately in 
order for the data to be available as element or session data for the duration of the call session.  For each parameter that is passed to 
the application from the calling subdialog, the “Parameter” setting should be configured with the name of the data that is passed.  The 
“Store As” setting allows developers to choose to store all passed values as session or element data.  The “Enable Digits Bypass” 
setting is used to activate a VoiceXML workaround to ensure expected functionality for a particular TDM or analog phone and flase 
for IP phones..  If this setting is activated, set to “true”, the “Audio Filler URI” setting can be configured to set a reference to the 
Flash: silence_.1s.wav file. 
 

string 

no false 

true 

Holds the name of a parameter passed as input to the subdialog. It must 
match the exact value specified in the VoiceXML page that calls the 
subdialog. This is a repeatable setting, so multiple values can be 
specified. 

string 

no

 

true false 

Session 

Data 

Determines whether the parameter passed to the subdialog will be stored 
as element data or session data. By making it element data, the 
information will “belong” only to this element, and so there is no 
chance that these variables will overwrite any other variables. 

boolean 

yes true

 

true

 

false 

Determines whether the digits field is used at the beginning of an 
application.  By default this is disabled. 

string 

no

 

true

 

true

 

This setting allows to configure an audio file for the prompt in the digits 
field.
