Kannel 1.4.4
I need to receive "long" sms (length > 160 ) by Kannel. If sms length less than 160 - all is ok. But if it is long sms kannel splits sms to 2 or more sms and not send sms. I get this error from smsc log
SMSC returned error code
0x000000ff(Unknown Error) in response to submit_sm PDU
What can cause this error ?
Use concatenation option for resolving this issue
max-messages = 3 concatenation = true
