Hello Support,
As a proxy server , How many concurrent calls can be processed by a
Kamailio which is installed on a VM with 4 cores and 16GB of RAM?
Your answer is much appreciated.

With RTPEngine? 5k-10k is a conservative estimate.
Without RTP? Essentially unlimited.

Hello Abtin,
this depends a lot on your configuration, if you use a lot of database
requests, if the database is local or remote, the database performance, the
amount of logging you are doing locally, do you handle RTP as well and so on.
If your server is not exceedingly using a lot of this mentioned IO operations,
you should be able to handle many thousands concurrent calls with one server.
But to have a proper answer for your certain scenario, you need to test it.
Best regards,
Henning

Hello Henning,
Thanks for your reply.
I understand the IO operations affects to overall performance. That proxy
server is actually a dispatcher (Load Balancer) to different Asterisk pbx
endpoints and is only going to log INVITEs and BYEs. Since I'm new to SER ,
Not really sure If should have RTP-Proxy as well, or not.(Your advice on
this is appreciated).
So how you think the concurrency would be now? (Considering 16GB of RAM
and 4 cores of Xeon-Silver 4114) I just need a estimated number by an
expert like you.
Thanks again for your response.

Hello Abtin,
again - this is hard to say. I know from a past setup in an carrier grade
environment that we sized it to have 3000-6000 concurrent calls per proxy. The
server were not much under load. They handled also more concurrent calls
without any issues in certain fail-over situations. And this was several years
ago, which slower hardware.
So the bottom line is - in a reasonable optimized setup on standard hardware
you should probably not run into CPU or RAM issues with Kamailio. The limiting
factor is in most cases the I/O.
Best regards,
Henning
