We have put a site with the SMS simulation. It works with users from the Cyclos demo site.
The site can be found at the page Cyclos / SMS simulator and there is a link at the login page of the demo site as well.
Technically seen the SMS simulation page is a ‘real’ simulation. It connects to the SMS controller software in the same way as a mobile phone operator or SMS gateway provider does. The configuration of the SMS controller and Cyclos used for the simulation are also ‘real live’ configurations. This means that the simulation is a good tool to test an operational (live) configuration. The simulation software, as well as the SMS controller/driver software will be published open source around the same time as the Cyclos3.6 version comes out. Technical documentation will be made available at the wiki.
