[Kamailio-Users] DIVERSION or UAC_REDIRECT or BOTH

I got confused: Using Kamailio 1.4.3 uac_redirect is been used to handle diversion, also the draft expired there is anew one http://tools.ietf.org/html/draft-levy-sip- diversion-10, is this used together with the diversion module, or no need at all. or is diversion module when you have customers registered in your system? I am do not have phones registered in my system at all, i use mainly the CR module, and i need to allow diversion headers. which one to use, or both?! Also i am scare to use the diversion due the CDRs will create a new record for that, who i will charge the call for?! :) and if i use UAC_REDIRECT should i be able to use the avp $dip and the following, from ROUTE to add to the accounting? Diversion header URI $di - reference to Diversion header URI Diversion "privacy" parameter $dip - reference to Diversion header “privacy” parameter value Diversion "reason" parameter $dir - reference to Diversion header “reason” parameter value __________________________ O the Great
