Does anyone have a solution for eliminating multiple INVITE's in the accounting table (acc) as a result of the caller putting someone on hold?
 
Here's my accounting section:
 
...
modparam("acc", "log_level", 1)
modparam("acc", "log_flag", 1)
modparam("acc", "failed_transactions", 1)
modparam("acc", "report_ack", 0)
...

route[1] {
 
 # -----------------------------------------------------------------
 # Default Message Handler
 # -----------------------------------------------------------------
 
 t_on_reply("1");
 
 if (method=="INVITE" || method=="ACK" || method=="BYE" || method=="CANCEL") {
  setflag(1);
 };
 
 if (!t_relay()) {
 
  if (method=="INVITE" || method=="ACK") {
   end_media_session();
  };
 
  sl_reply_error();
 };
}
