I don't know if this is a bug or it's intended to work that way so I'm posting the question on users list.
Here is my configuration: group = smsc smsc = at smsc-id = GSM modemtype = auto device = /dev/ttyACM1 speed = 115200 log-file = "/var/log/kannel/smsc-gsm.log" log-level = 0 connect-allow-ip = 127.0.0.1 my-number = 381651111111 sms-center = 381650000001 group = modems id = M600i name = M600i no-smsc = false detect-string = "M600i" init-string = "AT+CNMI=2,3,0,1,0" Because I selected no-smsc=false I suppose that the SMSC number will be incorporated in the PDU so the PDU will look like: 079183610500001011000C91836115 1111110000AA04D4F29C0E But Kannel does not incorporate the SMSC number in the PDU and the PDU passed to the modem is: 0011000C918361151111110000AA04D4F29C0E Is there any way to tell the Kannel to incorporate the SMSC number in the PDU, because the GPRS modem doesn't send the message if the PDU is not formed that way :( i.e. setting: AT CSCA="381650000001" does not work for this modem... Thank You in advance, Viktor Kerkez
