Depends on how many active channels, the algo used in the software EC, how the driver's compiled (optimizations)... it's not a simple answer. You need to benchmark it yourself. My short answer is: If you're not running into CPU issues, don't worry about the hardware EC. You're not saving anything. When you start having trouble with CPU usage, look at getting the module and adding it in. -A. ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Setting the timing to '0' tells the card NOT to try to recover clock from that span. Not what you want to do with telcos, but they should be in sync anyway. Failing that (i.e. if you MUST have different clock sources for each span, I would recommend a Sangoma multiport card. Putting two Digium cards in a server is ultimately more expensive and with no real net gain. -A. ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
