If the GW "collaborates" with caller they don't really need you in order to complete the call in the first place. In the situation when you don't control termination GW you should be billed by the period from receiving 200 OK from GW to the time you sending BYE to it. So, that if the session somehow continues after the BYE went out it's no longer your problem and you can legitimately dispute any charge beyond that from your provider. Therefore, there is not really much of opportunity for defraud. Regards, -- Maksym Sobolyev Sippy Software, Inc.
