Since then, I'm strongly interested in the implementation of my own PBX. As I often need to travel, I'd like to access my phone system wherever I am. This way I need a remote desktop software. So I'm going to create a web GUI to be able to configure the PBX even remotely.
And I got stuck at this point. Can anyone recommend me a tutorial/link/code example for creating a web GUI for my PBX project? I'm working in Visual Studio using C#. (But I'm also interested in C++ as well.) To define the default PBX functionality I use Ozeki VoIP SIP SDK. I use this Ozeki guide: http://voip-sip-sdk.com/p_533-how-to-build-a-pbx-phone-system-with-ozeki-voip-sip-sdk-voip.html along with the Codeproject article that I've mentioned above.
