Hi,

Thanks for you answer.

1.In fact I am not quite sure about what you mean for the first question. I am running the rtpengine daemon downloaded from github, sip wise/rtpengine.

2.There is nothing prompt on command cat /proc/rtpengine/0/list. The file is 0 bytes and empty.

3.Our kamailio is using loose route.

I still have my problem. Hoping for your analysis.

1. What rtpengine packages you have installed?

2. Do you see the stream kernelized by using 'cat /proc/rtpengine/0(table number you are using)/list'?

3. What parameters does kamailio sends to rtpengine (grep for the control port)? Do you use strict-source parameter? If yes, try without it, just for a test.

Regards, Stefan Mititelu

I am running rtpengine daemon on a CentOS machine functionally. SIP server is Kamailio. Vedio and audio calls are both OK with rtpengine.

But there is always prompts like following in rtpengine’s log:

<PastedGraphic-3.png>

So I am wondering whether this prompt is normal. Otherwise, what should I do to prevent this to happen?

Thx a lot!

Hello, friend.

Actually I set my rtpengine on a physical machine before I sent you my first reply to you. Problem still exists.

Now I changed some iptables rules and I can get info from “cat list” under the table 0. It prints these:

local inet4 10.109.247.87:30008 src inet4 10.109.247.87:30058 dst inet4 10.205.42.195:56220 stats: 14964 bytes, 87 packets, 0 errors RTP payload type 0: 0 bytes, 0 packets RTP payload type 3: 0 bytes, 0 packets RTP payload type 8: 0 bytes, 0 packets RTP payload type 9: 0 bytes, 0 packets RTP payload type 101: 0 bytes, 0 packets RTP payload type 105: 0 bytes, 0 packets RTP payload type 106: 0 bytes, 0 packets local inet4 10.109.247.87:30042 src inet4 10.109.247.87:30066 dst inet4 10.205.42.195:55744 stats: 77399 bytes, 68 packets, 0 errors RTP payload type 96: 0 bytes, 0 packets local inet4 10.109.247.87:30058 src inet4 10.109.247.87:30008 dst inet4 10.205.42.195:33875 stats: 14448 bytes, 84 packets, 0 errors RTP payload type 0: 0 bytes, 0 packets RTP payload type 3: 0 bytes, 0 packets RTP payload type 8: 0 bytes, 0 packets RTP payload type 9: 0 bytes, 0 packets RTP payload type 96: 0 bytes, 0 packets RTP payload type 97: 0 bytes, 0 packets RTP payload type 98: 0 bytes, 0 packets RTP payload type 99: 0 bytes, 0 packets RTP payload type 101: 0 bytes, 0 packets RTP payload type 102: 0 bytes, 0 packets RTP payload type 103: 0 bytes, 0 packets RTP payload type 105: 0 bytes, 0 packets RTP payload type 106: 0 bytes, 0 packets RTP payload type 107: 0 bytes, 0 packets RTP payload type 108: 0 bytes, 0 packets RTP payload type 109: 0 bytes, 0 packets local inet4 10.109.247.87:30066 src inet4 10.109.247.87:30042 dst inet4 10.205.42.195:39177 stats: 34105 bytes, 34 packets, 0 errors RTP payload type 96: 0 bytes, 0 packets RTP payload type 97: 0 bytes, 0 packets RTP payload type 102: 0 bytes, 0 packets

But I still got info like this:

The video call is great without much delay or noise. So any reasons else? Should I still concern about this log info?

1.In fact I am not quite sure about what you mean for the first question. I am running the rtpengine daemon downloaded from github, sip wise/rtpengine. What does 'dpkg -l | grep rtp' show?

2.There is nothing prompt on command cat /proc/rtpengine/0/list. The file is 0 bytes and empty. That means your streams are not kernelized and all the traffic passes through user space. I have never run rtpengine software on a virtual machine so I don't know if it should kernelize the streams in this case; you could try it. On real hardware, it should. Thus you should get rid of those errors. Check point '1.' and make sure that you have the necessary packages needed for kernelizing the streams referred in [1] (i.e. ngcp-rtpengine-kernel-dkms, ngcp-rtpengine-iptables) along with the rtpengine daemon (ngcp-rtpengine-daemon); those should be the minimum packages needed. Grep the README for "in-kernel" keyword for more info.

3.Our kamailio is using loose route. I was asking about "strict source" form README [1]. Nothing related to kamailio's 'lr=' parameter (if that is what you meant). However your problem is at point 2.

Problem still exists.

Your CPU still goes crazy?(it shouldn't) Or is just that the logs appear?
