I've never seen a phone system with five 9's reliability at CPE. That's why I refuse to promise it myself. Four nine's is easily attainable with regular PC-grade hardware. Five 9's is 315.576 seconds over a year, or five minutes. Four 9's is just shy of an hour of downtime a year. Our Meridian system isn't even meeting four 9's, but admittedly you can schedule a lot of the _truly_ down time to weekends / off-hours.
