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
Hi, Sure, Thanks, I installed rtpengine. default rtpengin.conf and after uncommenting these: num-threads = 16 num-media-threads = 8 http-threads = 4 in that, the same result is its working well for first 300-400 call. but after that packet lose starts. cpu load increased to 30% on all 4 cores. any advice about rtpengine.conf to better result?

Hello,
normally it’s not needed to set the num-threads* variables, there is some autodetection implemented. Why you want to run that many threads on a 4 core server?
I would now look to your network configuration, maybe it needs some tuning. You can also get statistics about dropped packets etc.. with system tools.
Cheers,
Henning

in that, the same result is its working well for first 300-400 call. but after that packet lose starts.

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

Hi,
Sure, Thanks,
I installed rtpengine. default rtpengin.conf and after uncommenting these:
num-threads = 16 num-media-threads = 8 http-threads = 4
in that, the same result is its working well for first 300-400 call. but after that packet lose starts.
cpu load increased to 30% on all 4 cores.
any advice about rtpengine.conf to better result?
Thanks for your help

my kamailio server has 8GB of ram and 4core*2.6 on esxi(dedicated)Ubuntu 22.04.1 LTS. is it low? htop on server shows load average 1.04 at max and I didn't see more than 10% load on any core of the server.
I've selected rtp media server because of playback of a voice file over incoming calls in the future usage

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.

"Packets dropped by kernel" means that some aspect of the system isn't keeping up with the network traffic. That could be tcpdump itself (see `-n` and `-B` options), or it could be the network hardware or driver, or the CPU or some other component could be maxed out (perhaps the disk that tcpdump is writing to isn't keeping up).
If you can't eliminate packet drops after making sure that it's not tcpdump itself that is the bottleneck, perhaps look into what tunables your network hardware supports (see ethtool), especially regarding RX queues.
Cheers
both of servers are on same esxi host. a 1Gb ether on every one. do you need any more information?

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
