Kannel displays the message, "Message was rejected" when sending using Kannel's http.

The URL of the SMSC of the service provider is correct and works in a browser. However the get-url returned is encoded with & that i think should not be there. How do I solve this problem. please help!

The url set in my kannel.conf file under the http group is that of the SMSC provider and ends with <send?username=un&password=pw&number=X&message=Y>

I am using sqlbox to queue messages
