sounds like a broken router to me <br><br>On Wednesday, April 20, 2016, Clive Lansink <<a href="mailto:clive@lansink.co.nz">clive@lansink.co.nz</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br>
Hi everyone. I often use Freeswitch set up as a client to provide a soft phone on my laptop.<br>
<br>
But recently I noticed a significant problem when at the same time I was running a standard Windows "ping" in the background. The speech I heard from the other end would often stutter, and the remote party complained that my speech sometimes sounded gittery.<br>
<br>
I reasoned that ping doesn't take up much network bandwidth so while in conversation I did something like copy a large file from my laptop to another PC on the network and there was no disturbance to the conversation. It only seems to be ping that causes this.<br>
<br>
Is there something about pinging that might impact on Freeswitch or VOIP? What would cause this?<br>
<br>
Further information.<br>
<br>
the above refers to the standard Windows ping command. I also have a Python script that pings a specified host, and running it also caused the call quality to degrade. I tried various changes to the source code to no effect, including:<br>
* only creating the socket once and then reusing it instead of it being created for each ping.<br>
* Only creating the data packet once and reusing it instead of it being created for each ping.<br>
* Using a very short packet size.<br>
* Eliminating the select statement and just sleeping for a period of time before reading the response in case the select itself was at fault.<br>
* Eliminating the step of dissecting and decoding the received packet.<br>
None of these made any difference so it seems to me that whatever it is must be something quite fundamental to something at the lower networking level.<br>
<br>
Thank you.<br>
