I enabled acc_radius module and acc module as well. I also followed the acc_radius module config as below. CDR are populated in Siremis. But can't initiated radius accounting.
# ----- acc params -----
/* what special events should be accounted ? */
modparam("acc", "early_media", 1)
modparam("acc", "report_ack", 0)
modparam("acc", "report_cancels", 1)
/* by default ww do not adjust the direct of the sequential requests.
* if you enable this parameter, be sure the enable "append_fromtag"
* in "rr" module */
modparam("acc", "detect_direction", 0)
/* account triggers (flags) */
modparam("acc", "log_flag", FLT_ACC)
modparam("acc", "log_missed_flag", FLT_ACCMISSED)
modparam("acc", "log_extra",
"src_user=$fU;src_domain=$fd;src_ip=$si;"
"dst_ouser=$tU;dst_user=$rU;dst_domain=$rd")
modparam("acc", "failed_transaction_flag", FLT_ACCFAILED)
#--------acc_radius acc params------
modparam("acc_radius", "radius_config", "/etc/radiusclient/radiusclient.conf")
