#### B2BUA ###############################################################
#The functionality is obvious from the name and what this service does is
#to hide the network topology from the parties that establish a dialog.
#To achieve this, the B2BUA poses itself in the middle and established dialogs with both parties.
#Then all it will do next will be to translate a receipt request or reply into the dialog from the other side and forward it to the peer entity.
