Yusuf, 

to what fraction of a second are you performing a compare? 

Carrier reconciliation has to take into account the propagation delay of
the call request if the calls traverse multiple switches. In past we
performed a compare on the basis of multiple details ingress,egress,
call time, answer time, etc.  If you are trying to perform a flat
reconciliation against call times only without any other details being
compared you will drive yourself crazy.  As for one or two second
differences, they seem to be in line if your are using VOIP for your
service offerings. If on the other hand you are using a local carrier
over copper then they should be closer on length, but not necessarily on
start or end times.


Hope that was worth something to you!
