I have created multiple SMSC SMPP connection.
after configuration i have send sms but sms is send with random smsc.
How can i control kannel to send sms with smpp which i want to send.
You can specify what smsc to send through in the submission to the kannel server, for example:
GET /cgi-bin/sendsms?smsc=$smsc&username=$user&password=$password&to=$receipient&text=$text&dlr-mask=$dlrMask&dlr-url=$dlrUrl
where $smsc should match a smsc-id you have in your kannel.conf
Documentation here, under "Table 6-16. SMS Push (send-sms) CGI Variables".
