Asterisk is perfect for a small to medium setup if you are doing a DIY system for yourself imo. A large Asterisk system will no doubt take more understanding and time to setup and outsourcing would be most likely be a viable option. Our asterisk@home box just came online this week, and I must say I'm well impressed. Telbum collected their outdated PBX system
-where the "major feature" was to put someone on hold! ..and they weren't shy to charge the rental for such a crap pbx either (over the 12 years!)
The Asterisk system is feature rich and provides phenomenal savings each month, while giving you a PBX which can rival large corporates.
