Asterisk Limit to handle concurrent calls

Asterisk Asterisk Support
1

Below is the server configuration-

processor : 15 vendor_id : GenuineIntel cpu family : 6 model name : Intel(R) Xeon(R) CPU E5640 @ 2.67GHz cpu MHz : 1600.000 cache size : 12288 KB RAM : 96 GB

How many Concurrent calls Asterisk Can Handle with this configuration ?
How to increase the limit ?

The number could vary by maybe up to two orders of magnitude, based on information you haven’t supplied. In general though, people will only tell you what works for them.

Codecs, music on hold, voice recording, conferencing, channel technologies, whether direct media or other native bridging is possible, will have a significant impact.

It is fairly safe to say that you will be CPU limited long before you are memory limited, on that system.

I am using Asterisk to send voice sms’s.
There is a pre-recorded voice file which I use to play using Asterisk. I am not using bridging, conferencing, etc…
Now, Can we caculate concurrent calls ?

Nope, no one here can hazard any guesses that would have any bearing on reality.
