I may be wrong, but I think the 5 9's relates to full system not to individual pieces especially when talking about a class4/5 switch. On a small scale deployment, that will be a problem as you won't implement full redundancy. Redundancy adds quite a bit to the cost of your deployment. As far as linux goes, it is at that level if you put forth the effort to make it's environment decent. I have multiple machines approaching 2 years of uptime, and many over a year of uptime. I have not had a machine in my colo space go down since we removed the one machine with a buggy NIC. So next step, is asterisk. Outside of a couple of deadlocks from kernel problems when I was compiling new modules, I haven't had asterisk knock over while doing normal calls. The downtime could have been dealt with by having some redundancy in the physical lines. I would have lost the calls on the line, but the calls could be reconnected immediately. I can say up front that I have asterisk installs running multiple months without problems. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
