> are very good free alternatives which can be managed also by non-technical people with zero telecom experience. Are you kidding me? I run my own PBX (would count as a SMB from a user/call count perspective). It doesn't run on any open source software, because all FOSS PBXes I looked at where ridiculously hard to configure. FreePBX is a great example there. Anyhow, I mainly looked into AskoziaPBX and Vodia after that. Askozia terminated their "diet" version and costs 250+ € (only one variant is offered). Vodia has a free version (5 extensions, which is exactly enough), and has a more granular licensing scheme. I didn't fully setup Askozia testing, but it looked quite nice. Vodia was also reasonably easy to configure (about 1-2 days initial setup and after a couple weeks I got all the kinks fixed).
