[cisco-voip] CDR Problem

[yy]

Hi guys,

I'm currently trying out CDRTool with ser for generating call detail 
records.Currently, I getting a problem in a single call session whereby 
when a user calls a certain destination and an invite is sent; if the 
called party does not reply in time, a reinvite is sent. However, both 
records are recorded in CDRTool, each having the same SIP Session. Why 
it this so? Shouldn't only one session be recorded?

            _Session start time                              SIP caller  
                                In      SIP destination                  
        Out      Dur    Price      KBIn      KBOut      Status      Codecs_
