Thats only if you could get full theoretical speeds. I have friends who work on ranked supercomputers that will tell you how far short most chipsets fall of the theoretical. Also remember the DS3 speed you mention is a one way speed. Voice being bidirectional means that it would pass the PCI bus in and some going out. Then if you plan on doing any recording, there will be another crossing of the PCI bus to either go out the ethernet cable to a drive subsystem that could handle the speed, or to a decent SCSI system locally. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
