Hi Agalya,
The onreply route is triggered when OpenSIPS receives a reply (from
network level) for the given transaction. This route does not reflect at
all the fact that the reply may or may not be sent out further to the
caller (to A).
For the kind of logging you want, you may consider using the accounting
module (acc) to log the early media and final reponses that are sent to A.
