You can, but from what I have heard (when I looked at it a few months
ago) it was pretty useless, so I would avoid it.
If you have alot of BYE, then that is where the difference is, all those
INVITES without a BYE you are not accounting for, but the gateway
provider always gets a BYE. Now you need to work out why you are not
getting the BYE, either the gateway is not sending them to you, which I
find strange, or if they are sending you are not recording...which again
is strange because you would either record none, OR all.
Maybe the calle is not hanging up the call for whatever reason, if that
is the case no BYE will get sent, but what your gateway provider should
do is to send you a BYE if their is a period of inactivity, if they dont
, u might need to find other clever solutions, by using session-timers,
to ask for re-invites from the user, and if you dont get them, insert a
BYE yourself.

PS I have cc'd this to the list, just in case others have similar problems,
