I have a server with 24 cores running at 2.4ghz and 16 GB RAM. How many
concurrent SIP sessions I can run from single instance of Asterisk on
this server? I wish to use G711 codec with echo cancel. And all calls
needs to be recorded.
What kind of capacity are you looking to achieve?
From my experience, Asterisk is not really much of a RAM hog. A couple GB
is good for a couple hundred simultaneous calls.
With 4 'Intel(R) Xeon(TM) CPU 3.40GHz' cores, I can handle a couple
hundred simultaneous non-transcoding calls with no recording on Asterisk
1.2.
With 24 cores and 16 GB on tap, you will probably find other resource
limitations before either CPU or RAM are a limiting factor.
Personally, I'm a 'don't put all your eggs in one basket' kind of guy.
Assuming a simplistic linear relationship between my host and yours, what
will you do when it crashes with 1600 calls in progress? What will you do
when you need to install patches or upgrade or ...
I like a couple of instances of OpenSIPS in front of several Asterisk
instances, even if OpenSIPS is on the same boxes as Asterisk.
What will be impact on no of session when G729a is used?
Significant.
