So I've been testing asterisk under LXC for a few days now and am very happy with the results. My test server is a 1.8GHz Celeron with 256KB cache and 512MB RAM and I have 20 containers each running asterisk (and apache/php,sendmail and a few other minor things) More for fun than anything else, I've tried daisy-chaining instances together - so 20 asterisks running on the same host, 0

Actually that's not entirely true. standard 568A/B wired cable does not split pairs for ethernet or DSX1 wiring. The problem is that DSX1 uses pins (1,2),(4,5) and ethernet (1,2), (3,6) (parenthesis show pairing). DSX1 must have the (1,2) and (4,5) pairs swapped to match the TX to the RX at each end, whereas normal ethernet does not, as the switch is cross-wired. Using an ethernet crossover ca...
