Hi Hope you are well
I am struggling to receive all DLRs. I thing they get stuck in the internal storage and are never reprocessed. Our provider as well as the handset receives the SMS and confirms delivery but our Logs and stats do not show delivery Herewith my config details: # kannel.conf group = core admin-port = 14000 admin-password = foo status-password = bar admin-allow-ip = '*.*.*.*' smsbox-port = 14003 log-level = 0 log-file = "/var/log/kannel/kannel.log" box-allow-ip = "*.*.*.*" access-log = "/var/log/kannel/access.log" group = smsc smsc = smpp smsc-id = foo host = foo.bar.com smsc-username = foo smsc-password = bar port = 2775 system-type = "0" service-type = "CMT" transceiver-mode = true msg-id-type = 0x01 group = smsbox smsbox-id = BOX1 bearerbox-host = localhost sendsms-port = 14014 global-sender = 14014 log-file = "/var/log/kannel/smsbox.log" log-level = 0 access-log = "/var/log/kannel/access.log" # For Sending SMS push group = sendsms-user username = foo password = bar default-smsc = foo concatenation= true max-messages = 5 forced-smsc = foo # For Receiving SMS group = sms-service keyword = default catch-all = yes max-messages = 1 post-url = foobar.com group = smsbox-route smsbox-id = BOX1 smsc-id = foo This is what our status.html is seeing: SMS: received 0 (0 queued), sent 1 (0 queued), store size -1 SMS: inbound (0.00,0.00,0.00) msg/sec, outbound (0.00,0.00,0.00) msg/sec DLR: received 1, sent 0 DLR: inbound (0.00,0.00,0.00) msg/sec, outbound (0.00,0.00,0.00) msg/sec DLR: 1 queued, using internal storage Regards, Ariel
