Adding Diversion header into the reply 302 Moved Temporarily

@status-line

Hello

I'm trying to build the following HMR:

• Searching for the reply  302 Moved Temporarily
• Storing the parameter TO
• Adding the header Diversion into the reply 302 Moved Temporarily
• The diversion header must be equal to the parameter TO already stored

Below is the code for this HMR; But it's not working.

Would you please help to find out what's wrong.

 

P.S: The parameter Redirect action = proxy is already set in the Sip-interface of the realm in question
