I don't know if it's the right place to ask this question, but i'll do it. Got some traces from TAPIN file with the number of SMSC as BNumber;in other words,when our Outroamers in some countries try to send SMS, their serving MSC send many times SMS to our SMSC with the number of SMSC as BNumber. Is it a problem in the acknoledgment of the MAP-MO-FORWARD SHORTMESSAGE or a bad formating of their TAP files? Hi all!
