RE: [Asterisk-Users] IVR Capacity

[Serge Schumacher]

With 2 quad E1 I can handle 240 channels at the same time, so those 240 channels have to playback voicemenus on the same time.   The survey will have about 30 questions and the complete survey will take about 20-30 minutes   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Shawn Porter Sent: mardi 20 décembre 2005 23:06 To: [EMAIL PROTECTED]; 'Asterisk Users Mailing List - Non-Commercial Discussion' Subject: RE: [Asterisk-Users] IVR Capacity   my own criticism.  I just talked with a friend about erlang tables.  completely blows away all the stuff I just wrote below...   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Shawn Porter Sent: Tuesday, December 20, 2005 4:47 PM To: 'Asterisk Users Mailing List - Non-Commercial Discussion' Subject: RE: [Asterisk-Users] IVR Capacity Serge,     How are you going to be building this server?  I am not going to claim to be any sort of expert on sizing, but I do have some experience as an IVR designer/developer.   In one of your previous posts you mention E1 cards.  In order to get 300 msgs at once you would need to be running 10 E1s, is this reasonable? How many questions are there in your survey, how long is an average call going to take? say you have 5 questions, and a complete call will take approx 2 minutes allow for call-setup and call-breakdown - 15 sec should allow for 26calls per hour per channel @ 30 channels = 780 calls hour using just 1 E1 In this case you would only have, at maximum, 30 prompts playing at any one time.  From what I have seen in this mailing list there are servers out there doing a lot more than that (but I do not know what the hardware is).   I have built systems running at that level of traffic using the Contarra IVR platform and running on a P4-1.6GHz with 512MB on a dialogic card. Surely an * box with a decent CPU & Memory can handle it no problem.   Now that I have gone stated all this for the world to criticize, please let me know if I have made any critical mistakes/assumptions.   Shawn P.S Contarra & Envox I know, Asterisk I am learning.   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Serge Schumacher Sent: Tuesday, December 20, 2005 4:23 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [Asterisk-Users] IVR Capacity Hi,   Do you think * could play around 300 voicemenu messages simoultanously?   Regs, Serge
