How to configure Kannel SMS Gateway in Windows 7 ? I have no idea about this. Kannel site it self provide only the configuration for Linux platforms :(
Am not sure if would work directly on Windows 7 but i was able to get mine working via Windows Virtual PC
A. Create A new Windows Virtual PC
B. Download CentOS and install it on Windos Virtual PC (So many tutorials on you tube)
C. When your server is setup ... there is a nice tutorial here http://www.creativelodge.net/internet/how-tos/install-kannel-sms-gateway-in-centos-5/ but use use yum install kannel
and use the tutorial to configure kannel
You would have kannel up and running on a Windows 7 perfectly
I hope this helps
Thanks
EDIT: Above link does not work. The working link is Install Kannel SMS gateway in Centos 5
