Asterisk@Home version 2.7 is out and as usual the good folks over at Nerd Vittles have the low-down on all the installation and upgrade issues. If, like me, you’ve been toying with the idea of setting up a home Asterisk system, the Newbie’s Guide to Asterisk@Home 2.7: Unabridged Installation and Upgrade Guide might be just the motivation you’ve been looking for. Ted Wallingford points out that for the cost of a $200 used PC configured with the free Asterisk software you can have “more signaling power than your typical $60,000 SS7 switch.” Not to mention cool features like email delivery of voice messages.
