Dear All

Can you please let me know how can we get DLR's of SMS being rejected due
to invalid number on SMSC level as operator is rejecting the SMS by the
following error

SMSC returned error code 0x0000009b (Unknown/Reserved) in response to
submit_sm PDU

and due to which the sender awaits delivery of the sent message

Is there any workaround to send failed delivery to the message sender
