[Freeswitch-users] Developing with FreeSWITCH - getting started

I want to create an app for call handling on FreeSWITCH, in particular stacking calls, connecting to audio channels on a sound card in response to mouse clicks etc. What’s the best way to get started? In particular: What are my options, API / Language wise? I’m familiar with Python, Bash, and Basic. Are these options? Any tips, or pointers to useful ‘idiots guides’ / ‘howtos’ …? Thanks! RICK
