SMS - Trouble sending SMS with Kannel

Hello all,

I think I finally got Kannel (1.4.3) and my GSM modem (Huawei K3770) set up. I tried to send an SMS to a mobile phone through the HTTP command:

http://localhost:13013/cgi-bin/sendsms?username=tester&password=foobar&to=+2772xxxxxxx&text=hello

The result I get is: "3: Queued for later delivery", but when I check the bearerbox log I get this:

This keeps happening so the queued SMS is never sent. The following is my configuration file for Kannel:

Any tips on what I am doing wrong would be greatly appreciated!

I managed to solve this. The modem had automatically allowed a mobile broadband connection to be established so it was too busy for Kannel. By disconnecting the connection (but not the modem from the physical USB port) and restarting Kannel, I got everything running smoothly.
