How To Setup Asterisk@Home How to set-up a simple, IP-based PBX (private branch exchange) Have you ever wanted one of those nifty office telephone systems? You know, with extensions, your very own receptionist, voicemail for every cubicle, an intercom system and all the other bells and whistles.

In fact, Microsoft introduced SMB version 2 with Windows Vista in 2006, improved on it in Windows 7, and developed major revisions of 2.1 and 3.0 as of 2012. Samba runs on the Linux (or UNIX) server.
