Hi Alvaro,
I have tested this issue with many subscribers phones and all of them are
having the same behavior, the SMS is received but kannel state it as
DISCARD meanwhile the tcp dump that i have extracted from my firewall shows
that the SMSC had actually submitted the corresponding "submit_sm_resp" PDU
but it seems that kannel ignored it or couldn't match it properly.
Regards,
Amir
