Hello, I have an issue I have configured kannel and am able to bind to SMSC provider. Not when I send message to SMSc Provider am getting an error message in log as below 2018-11-09 14:00:20 Receive DLR [SMSC:airtel] [SVC:] [ACT:] [BINF:] [FID:] [META:?smpp_resp?] [from:zzzz] [to:260976298808] [flags:-1:-1:-1:-1:16] [msg:36:NACK/0x00000015/Invalid Service Type] [udh:0:]
