asterisk users - Aug 2013 - Asterisk 1.4 CDR vs VoIP Innovations CDR

When I compare my total minutes on the bill from VoIP Innovations, to 
the number from our CDRs, I'm finding a smalish (3-4%) discrepancy in 
the count of minutes.  I'm wondering why it's there.

Are there different methods of counting the billable start or end point 
of a phone call?

If it matters, I'm counting more termination minutes than they are and 
they're counting more origination minutes than I am.

May be as simple as this:

When you terminate a call you start the call before they even get it.

When they originate a call, they start the call before you get it.

Just a guess without really thinking about this too much.

If I remember correctly, they bill in sub-minute increments, something like
60 second minimum, then every 6 seconds after that.  In other words, if you
have a 20 second call, it's billed as 60 seconds, however, if you have a 62
second call, it's billed as 66.  I don't remember what they're
specific
increments are, but I don't believe it was a straight bill.

Are you finding that you're off by just a few seconds per call, or by
minutes? When you say you're off by 3-4%, are you saying your CDR reports
100 minutes on a call and they are showing 104 minutes, or vice versa?
