Respond Msg to Deliver Message

Hi all,

I try to use Kannel 1.1.6 to connect to SMSC via SMPP with a service
number assigned to GW. When a subscriber send any SM to service number,
the msg will deliver to GW. 
In the source, file smsc_smpp.c, function: handle_pdu():

case deliver_sm
(void) bb_smscconn_receive(smpp->conn, pdu_to_msg(pdu));
resp = smpp_pdu_create(deliver_sm_resp,
pdu->u.deliver_sm.sequence_number);
break;

Thatn means, GW only respond to SMSC a deliver_sm_resp message. 

In fact, the sender who send a SM to service number (GW) would receive
a msg with content: "No service specified" 


Who know why ?


Does Kannel 1.1.6 support flash message?

Thank for any reply!
