asterisk users - Jul 2008 - Asterisk dimensioning

Hello all,

I need to install asterisk for 900 sip users with 2 PRI ports.
It is posible to handle this number of calls/extensions with only one
asterisk machine?
Which is the best way to install that? two asterisk with openser. One
asterisk with openser .....
Is it necesary run a SER server on this enviroment?

Any clue will be welcomed.

Thanks in advance.

How many calls do you expect to be going at one time?
Do you have any sip trunks for the users to call out on? Unless this ratio
really works for you I'm not sure a 15 to 1 ratio works for most people.
I wouldn't just depend on a single server for this purpose.
I'll leave it to the cluster guys to describe the ideal setup you should
use.
I have an idea of how I might do it, but I wouldn't want to get it wrong.

Tom

Is this correct?  60 channels (assuming an E1 connection, not a T1) 
between 900 extensions means only 1 in 15 people can be on the phone at 
once - which is a pretty low ratio.

If this is indeed correct and you aren't using VoIP trunks to provide 
additional channels, then with a reasonably powerful machine, this 
should be possible, particularly if the phones are configured to use the 
same codec that your PRI line uses (either G711a or G711u)
