anyone experienced to do on smpp with perl?
i wonder how to receive the delivery receipt from the smsc.
$resp_pdu = $smpp->query_sm_resp(
message_id => $msg_id,
final_date => '',
error_code => 0x00,
) or die;
die "Response indicated error: " . $resp_pdu-> explain_status()
what should i declare with $state and how to retrieve the value of message state?
