asterisk users - Apr 2004 - Largescale Asterisk setup - 1000 external lines

Hi there 

Does anyone know if it is possible to install a largescale asterisk cluster 
with up to 1000 external lines.
Redundancy and loadbalancing would surely be a must for a such system, but 
which other things should be considered? 


Best Regards

Are you planning on using analog or IP phones for users?

If IP phones you need to look at choice of codec, network bandwidth for 
the X000 users, how you will allocate users to servers and how users 
allocated to various servers will communicate with one another.. If a 
server fails how will you redirect the clients that were attached to 
that server to another server?

Then there is the issue of line selection since you can't connect 1000 
lines to a single server, how will this be load balanced?

If you are trying to create an SSI cluster I think you have you work cut 
out for you because AKAIK it can't be done yet and Asterisk does not yet 
share registeration information between servers..

Good luck!!

How much of this 1000 lines will talk simultaneously?
You will need around 11-12  TE410P cards with 45-50 channel banks,  and 
cumpers with mainboard based on Intel 750X or Broadcom GC-XX chipsets
put how many computers depends on the max talk/idle lines ratio.
