[Kamailio-Users] DIVERSION or UAC_REDIRECT or BOTH

[Omar]

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?!
