For our product we have to use a VXML subdialog to another external file, but this given subdialog have less var elements than the param elements we are sending.
Here is an example
<subdialog ...>
<param name="Param1" expr="'1'"/>
<param name="Param2" expr="'2'"/>
...
</subdialog>
In the caller, and
<form ...>
<var name="Param1"/>
...
</form>
Is there a way to declare a param as optional in a subdialog ?
Many thanks,
As an answer to myself, sadly there is no possibility you can pass more parameters to a subdialog than it expects.
Thus, we have to pass the exact same amount of parameters as the numbers of variables that are declared in the form.
