Couple of problems with your wish. 1st, at 60 FXO, stop using analog and get T1 or E1 links in. You probably will receive a discount on the links and you get away from all the analog problems. Not to mention at least the cost of 2 or 3 TA750 setups and the FXO cards. 2nd. You don't want that many TE4XXP cards in the same machine, one crash and all calls go down. Spread your risk. 3rd. A quad anything is going to cost you more than 4 single cpu machines with similar cpus. SMP does not scale at x*cpu speed, it is about 70%-80% additional per CPU. So 4 single machines will be about 1 whole CPU faster than the quad anyways. 4th. echo cancellation is always required with analog links. So the suggestion is 2 or 3 decent P4 machines and spread the cards around. Maybe use a forth machine to hold all voicemail. Consider 1 machine with the the PSTN connections and and 2 channel banks. Machine 2 and 3 handle only channel banks with 2 cards apiece, Machine 4 is voicemail and possibly the SIP interface. Machine 4 only needs an ethernet card, raid, and a decent amount of ram. Machine 2 and 3 need a decent ethernet card and decent ram, maybe an IDE drive each. Machine 1 needs decent memory, ethernet card, and possibly just an ide drive. A little extension magic and all is good to go and less than a quad anything board. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
