CUPI - How to create a Routing Rule with "send call to Call Handler"

Hi,

I want to create a Routing Rule with "Send Call to Call Handler" using CUPI.

The request I use is :

POST /vmrest/routingrules HTTP/1.1

Accept: application/json

Server:

/vmrest/routingrules/d2664c39-03a1-45c9-a9b8-7d548fa4f94c

But when I look to the created Routing Rule on Unity Connection Administration Interface, there is no radio button selected for "Send Call to":

What is wrong with my request ?

Thank you,

Fabien

When I set the value "2" to "RouteAction", it works.
