Hello,

do you observe (too) high load on the system with the standard system 
management tools?
If you want to just proxy calls, my recommendation would be to use rtpengine. 
Here you should be able to achieve higher concurrent calls rates, if you have a 
few CPUs on a decent machine.

Cheers,

Henning

Subject: [SR-Users] rtp lost package in 300 concurrent calls and above

Hi,
I've installed last version of kamailio over ubuntu. I need to broadcast 
machine calls to destinations. my concurrent call should be around 300(my pstn 
channels), so I start calls with cps around 20, because my calls contains a 
less than 30 second and if destination answer the call it will hanged up in 
less than or equal to 30 seconds.
My problem is: to test my kamailio config, I'm using startrinity sip tester 
over an win server 2019 on local network. and it shows about 20% lost package 
on rtp and a jitter about 500ms. what should I do? my config is based on rtp 
media server module. Is there a complete working sample config for kamailio 
with rtp media server module?
I tried rtpproxy and rtp engine in past and the same problem happened.
Thanks for any help you can provide
Best regards
