Just about anything with a PCI bus, maybe even a P133 would cut this. > b-) a peak time 10 simultaneous calls facility and later 10 simultaneous callers needs to switch up to either T1, PRI, or E1 depending on location, cost, and extra needed features. > c-) going upto 10,000 simultaneous calls scalability 10,000/30(E1) is 333.33 circuits. At a max of 4 circuits a board you are looking at 84 cards. With a max of 2 cards per machine, you are looking at 42 machines. My guess(and a bit uneducated in your needs) is that you will not have 10,000 people calling at the same time. My guess is you might get 10,000 over the course of 1 hour which breaks down to a call initiation every 2.777 seconds, or 167 calls per minute. With this in mind, you only need 167*call duration + fudge factor number of lines. You quote of a 1 minute call time would make you need 167 lines plus some fudge of about 10 or so lines. 177 lines is only 6 E1 circuits or 8 PRI circuits. Both of which could be handled by 2 TE4xxP cards on one or two machines. For that kind of call load, your interaction application should be written in C and made a module of asterisk to eliminate startup costs. > 2-) Where can i procure the hardware from Digium, or one of the resellers listed on their site. > I was thinking of taking 30 access channels of 64 Kbps and 1 signalling > channel of 64 Kbps (30B + D). for an ISDN compatible EPABX > Kindly let me know of your opinion > Thanks > digvijay -- 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
