Thank you for the Answer:
Our customer is  sending call forwarding to a toll free number using the diversion header

the scenario is :

customer---->proxy------>Kamailio----->carrier----->

not sure where the diversion have to touch the Kamailio, if kamailio has only to pass through the headers, but i only got a 404 from the  carrier.
but not a 302 nor similar, what i know is we send the call, but i do not have any additional traceback.


When i should use the UAC_redirect and.or Diversion modules?!

If you just want to route messages with Diversion headers, you don't need to do anything, the proxy will just route them as any other message.

The acc module (if you use this for accounting) will not evaluate the diversion header on its own.

If there is a Diversion header in the message (with eventual parameters) you could use this pseudo-variables to access it/ them.

Does this information helps you?
