Hi Digvijay- I have done something similar to what you're looking to do, so maybe I can help you. I currently have a system that takes up to 600 simultaneous IVR calls, supplied by a large private DMS-100 PBX over 20 E1 spans. I think my load is a little higher than yours however, because the calls typically are very short (5 seconds).
Here's a summary of what I've found - please contact me directly for more detail: I suggest: * Use 1 processor (example: 2.8Ghz P4) for every 4 E1's (example: one TE405P card) when you have that much call setup traffic. * Try to do as much as possible using the dialplan (extensions.conf). AGI scripts are very powerful but cost you in performance when you're running large numbers of lines. * For the processor to use, see the Wiki for suggestions. I've used P4 and Xeon based Tyan and Intel motherboards with success. * Where you get the hardware depends of course on where you are located. Good luck! Scott Stingel Scott M.

I wish someone could take their valuable time off to answer my query in detail. I wish to set up an IVR system that can allow user authentication and therefter accept 2-3 inputs from users ..generate a key and transmit the same in voice back to the user . The system will intially have small load but if the whole package in future may have huge loads .. from 1000 to 10000 simultaneous peak time callers with 1 minute duration calls ( just to mention how scalable we would ideally desire it to be ) At present we would need a maximum of 10 simultaneous users peak load capability. >From what i know so far asterisk is the most cost effective and sound option. Now to my question.. 1-) What would be the hardware requirements in these different cases a-) for a single analog phone line for demo purposes intially to b-) a peak time 10 simultaneous calls facility and later c-) going upto 10,000 simultaneous calls scalability 2-) Where can i procure the hardware from 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 _________________________________________________________________ Easiest Money Transfer to India.
