Hello guys...

How many calls per second i may be able to handle per core ?

When i run:
asterisk -rx "core show channels"

78 active channels
35 active calls
15089 calls processed

My current Server has:
16 x Intel(R) Xeon(R) CPU L5520 @ 2.27GHz / Each Core


but the load remains around 0,15 ---> 0,25

memory, i have seen is pretty much near to nothing, hard drive speed does not really affect that much (cause is not heavy voice recording)

I just want to have an idea of how many calls can i place per second and how many calls can i do concurrently... so i can have a better idea on how many servers i do need to buy !!!

The most important question is how many calls per second can your carrier handle.

As for VICIdial, it's not a fixed metric. It depends on the hardware of course, but also on the codec used, the answer percentage, the average length of calls, the number of concurrent channels, etc...

Well, i am a "CARRIER", by all the carriers i got, combined, i can easily handle over 400 CPS

we are doing ACD = 15 to 20
Codec = G711

But i want to have a "metric" on how many Servers or how can i handle the most CPS and the more channels / people talking, so i can estimate how many servers i should buy

Any idea or suggestion on which CPU and how many cores and how many CPS and how many concurrent they can handle...

That would be greatly appreciated

Right now i got:
Intel(R) Xeon(R) CPU L5520 @ 2.27GHz / 16 Cores


Would i get better CPS / Channels if i use a dual core, or single core is just fine ? the more cores the better ? how many CPS can i get with 16 cores and that kind of CPU ?

Thanks so much !!!

Thanks !!!

Asterisk does not scale very well on a single machine, no matter the number of CPU cores on it. You would get much more capacity having 4 separate quad-core servers compared to a single 16-core server.

Thanks so much !!!
