[SR-Users] Dialogs not deleted on BYE

Tue Mar 17 20:58:37 CET 2015

Thanks Daniel,

>From the request_route block I call the ims_charging module function Ro_CCR().  This is non-blocking and one of the parameters in the call is the route block to be called ( e.g. CHARGING_CCR_REPLY ) when the response to the charging request is obtained.  Looking at the code, the  Ro_CCR() function does a t_suspend() and then the ims_charging module does a  t_continue() when the response is received.  Then the specified routing block is called and processing of the INVITE continues.

route[CHARGING_CCR_REPLY] {
  xlog("L_DBG","cca_return code is $avp(s:cca_return_code)\n");
  switch ($avp(s:cca_return_code)) {
    case 1: #success
        route(LOCATION);
        route(RELAY);
        break;
.....
}

It appears that the RR parameter that is added during the request_route processing (via dialog tracking) is no longer there when the INVITE continues being processed in the CHARGING_CCR_REPLY route block.  Is that what you would expect? Any pointers to solutions?

Hope that answers your question.

Cheers
Shane

In what callback do you need it?

Cheers,
Daniel
