I agree 100%. But, I don't believe any of that can be changed anyway on the digium cards; I'm 90% sure the card's buffering (and therefore interrupt frequency) is hardwired within the chip sets. (I've not tried to analyze the T1/E1 cards, only the TDM card.) _______________________________________________ --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
