It could happen from SMS MT that has SCCP Calling Party GT that is different than MAP SM-RP-OA (which is the SMSC address). What I have seen is that a lot of valid SMS MT has such combination, so that we can not just block them. My question is that why, in reality, do we have such question? Which elements change the SCCP Calling Party GT? Appreciate your response. Hello,
