We use IP501's with dual TDM400P's (6 x FXO) here and so far, everyone has been satisfied with performance. No big complaints other than occasional minor echo but nothing's a show stopper. Voice quality has been rated as "very good" rather than "great" as with our old Avaya PBX but for the price, I can't complain too much. I don't even have QoS setup yet so I expect performance to be even better once I get a new switch in. _______________________________________________ --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
