Any leads maybe under ethtool -S [interface] , possible some kind of checksum / network "interference" , possibly the tx side is doing more work? https://www.kernel.org/doc/Documentation/networking/checksum-offloads.txt On Thu, Sep 21, 2017 at 7:49 AM, Stanislav Sinyagin <ssinyagin@gmail.com> wrote:
I actually mentioned it in the thread. Yes, after switching the roles of the boxes, the problem switches too. It's only the call origination box that is producing the jitter on outbound RTP. I also verified it with packet capture on both sides. The RTP leaves the box with jitter already.
I'm still analyzing it, trying to find the reason for the jitter.

Just curious, have you tried switching the boxes and seeing if you get same situation?

but the interesting thing is, that it's the device that originates the SIP call is producing a significantly higher jitter than the one receiving the call.
The originating command looks like this here, with a SIP address as destination, and a number in local XML dialplan as transfer application: https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Ffreeswitch....

with jitterbuffer, it now works as expected. So, the sending party was generating extra jitter.
I am playing the same audio file in both directions, and then compare the recorded audio with the original by Sevana AQuA software. This allows me to detect packet loss in a heterogeneous environment where the voice goes through RTP proxies and TDM.

What occurs if you send identical audio for the same duration? IOW, play the sound file for each call.
