Hi all, I'm new to VoIP, now we have a project that needs a PBX with client APPs. In our team we have argument for choosing PBX. By so far, we have following candidates: A: Open source 1) Asterisk PBX (http://www.asterisk.org ) (with longest history that almost every one knows it) 2) FreeSwitch (http://www.freeswitch.org ) (A lot people recommended it to us) B: Commercial 1) Vodia PBX (http://www.vodia.com). It comes from SNOM, but acquired by a HongKong company now 2) PortSIP PBX (http://www.portsip.com/portsip-pbx ). It also includes VoIP SDK, WebRTC and offer rebranding app for free. My boss prefers the Open Source PBX since they are free, but our CTO prefers the commercial editions, according to whom the business PBX has better support, and the performance is good, and easy to use - considering our team all are new to VoIP/PBX. We have did some searching of FreeSwitch, it seems the sofia stack comes from Nodia. Here's my question: 1. Does the Nokia still maintain this stack or not? 2. Any commercial support by FreeSwitch developers? Can I got the quotation? 3. Is it easy to compile and setup FreeSwitch? 4. Which FreeSwitch version is recommended? ( 1.6?) Thanks in advance . Best regards,
