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
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

Most likely it's your hardware or network, I run well over 1k calls with StarTrinity with no loss. Whats the load on the boxes? What does tcpdump say? What do the interface loss stats say?

Hi, cpu and ram load on both servers are not high. how can I know about your questions answer?( What does tcpdump say? What do the interface loss stats say? )
Thanks for your help

It's probably the matter of Number of Open Files Limit in Linux you can check it by : ulimit -Hn And ulimit -Sn And if the number are low you can increase it by:
sysctl -w fs.file-max=500000
And test it again.

I changed the open file limit from 1024 to 1048576 and checked that. No changes happened by that. I think its a problem in esxi load support, can it be the problem?
