I am receiving the following error after transitioning to a new form after a <catch event="customTimer">
     CALL_ERROR; http://luann/test/dtmfTest.vxml
     at line 35: fail with vapp error 2
 
This only occurs if the interpreter was in a form that is collecting digits and the catch tries to transition to a 2nd form that also collects digits.  In the debugs, you can see the above error is a result of digit collection on a leg that already has digit collection enabled (from the previous form).


If I change bargein="false" this error does not occur, because the first form isn't yet collecting digits when the EVENT is throw and sends the interpreter to the second form.
 
Is there a way to explicity tell the vxml interpreter to stop collecting digits in the previous form?
If not, how can I transition between two forms that both collect digits using a <catch> ?

 
What else have I already tried?
I have tried combining the fields, grammars, and catch into a single form using  <goto nextitem="fieldname">
modal="true"
moving the <catch> to scopes document and dialog
 
See error output at bottom of this post.

 
The following dtmfTest.TCL and dtmfTest.VXML are run as a hybrid script.  The TCL throws a simple EVENT to the vXML after a timer expires.

The same thing happens when a custom <catch event="goToNewURL"> occurs and transitions to a new document that collects digits.  When the field/grammar loads on the new document, an error occurs becuase of the digit collection.

This scenario is not supported. Vxml can not stop the digit collect for the first field.
 
Thanks.
