Since the DTDs of the documents returned by the XML API are the same as those for static 
element configurations produced by Unified CVP VoiceXML Studio, dynamic configurations 
may also utilize substitution. Using substitution in dynamic configurations, however, makes little 
sense as the dynamic configuration is produced by programming code which could just as easily 
set the appropriate value rather explicitly rather than assemble it using substitution. To be 
comprehensive, this section briefly describes the contents of the 

<substitute>

 tag.  

A value for a setting, audio source, audio TTS or any other configuration option that supports 
substitution contains static content combined with integer values encapsulated by braces. When 
this format is detected, Unified CVP VoiceXML Server knows to replace (substitute) the parts 
encapsulated in braces with the dynamic data. For example,  “

http://{0}/grammar/{1}

” as a 

value for a setting indicates to substitute some dynamic content for “{0}” and “{1}”, where the 
indices are used for uniqueness (the same index can be used multiple times in the same value or 
in separate values if applicable).  

This is where the 

<substitute>

 tag comes in. Each 

<substitute>

 tag specifies what dynamic 

data to substitute for a particular number surrounded by braces. The 

index

 attribute must be an 

integer that matches the number to substitute. A diagram of what it can contain is shown in 
Figure 6-3.  

 

The content to substitute can be one of the six possible tags: 

   

call_data 

–  Represents call information such as the ANI.  

   

– Represents element or session data.  

   

– Represents information about the user associated with the call (available only 

when the user management system is turned on and the call is associated with a particular 
UID).  

   

– Represents the current time or the start of the call.  

   

– Represents the activity taken by the caller in this call.
