Hi,
@ou812 , FusionPBX is the most comprehensive and complete GUI option I have also been able to find for FreeSwitch. It is not perfect but it is quite good. You do not really need it to use FreeSwitch but it makes some tasks (especially for FreeSwitch beginners) quite easy.
The point I fel more uneasy with the project is that while it is open source (you can get the code and expand it at your heart's content), development is mostly driven by one single person with eventual collaboration from a few others. While he has done an amazing job, if tomorrow he decides to stop working on this, the project would be pretty much in limbo. However as I said, use it as a tool to get more familiar with freespeech. Should come the day that FusionPBX is not longer an option, you will be able to simply do everything directly on FreeSwitch.
