I am in need of some direction in researching PBX systems. I've got a basic Systems Administration question regarding PBX's, but I'm not sure which SE site would be most appropriate for that... Would it be Server Fault, or something else?
If it's a shopping or product comparison question, it's not going to be on-topic anywhere. Otherwise, ServerFault is probably your best bet. Read QA is hard, let's go shopping and Gorilla vs Shark first.
