Hello. I have a very long queue of messages at the SMSC that Kannel is picking up very, very slowly. We did a tcpdump and they concluded that Kannel was not sending a submit_sm_resp after getting a submit_sm causing the SMSC to re-transmit the submit_sm over and over, hence the delay.
Please help. My settings are as follows: # ======================== CORE ========================= group = core admin-port = 13000 smsbox-port = 13001 admin-password = password log-level = 0 store-type = file store-location = /var/log/kannel/store_file store-dump-freq = 1 log-file = "/var/log/kannel/bearerbox.log" access-log = "/var/log/kannel/bearerbox_access.log" box-deny-ip = "*.*.*.*" box-allow-ip = "127.0.0.1" dlr-storage = mysql sms-resend-retry = 50 # ==================== SMS DAEMON ======================== group = smsbox bearerbox-host = 127.0.0.1 sendsms-port = 13013 log-file = "/var/log/kannel/smsbox.log" log-level = 0 access-log = "/var/log/kannel/smsbox_access.log" http-request-retry = 10 #sendsms-url=/send mo-recode=true #---------- MYSQL DLR -------- group = mysql-connection id = mysql_dlr host = localhost username = dlr password = dlr database = dlr max-connections = 1 group = dlr-db id = mysql_dlr table = dlr field-smsc = smsc field-timestamp = ts field-destination = destination field-source = source field-service = service field-url = url field-mask = mask field-status = status field-boxc-id = boxc #=============== SERVICES =============== include = "/etc/kannel/default_service.conf" #=========== SMSC CONNECTIONS =========== group=smsc smsc=smpp smsc-id=saf_receiver_b interface-version=34 host=192.168.9.93 receive-port=6695 system-type= smsc-username=<username> smsc-password=<password> log-level=0 source-addr-ton = 2 source-addr-npi = 1 dest-addr-ton = 2 dest-addr-npi = 1 msg-id-type = 0x01 alt-charset = "ASCII" alt-addr-charset = "GSM" enquire-link-interval = 5 max-pending-submits = 20 flow-control = 0 window = 50 wait-ack=120 wait-ack-expire=0x02
