<div dir="ltr">If you take a look at the headers, it's somewhat self explanatory -- this is for a 53 second call.<div>First it has the raw bytes in -- which includes dtmf, comfort noise, etc. Then it's broken down for where specifically it came.</div>
<div>If media_bytes or packets is 0 for either side, that will indicate real 1 way audio (assuming FS is in the media path).</div><div><br></div><div style>"skip", "jb" (jitter buffer) and "flush" are all probably bad things.</div>
<div style>On the way out, that means either the CPU couldn't keep up or maybe some issue with the input (not sure about the last one)</div><div style>But for the inbound, that's an indication of some issue with the incoming media. It could be a real issue with the remote endpoint, or might just be a temporary issue with the link.</div>
<div style>Adding skip+flush = 55 packets. Of the total media packets 2574, let's find a percentage: 55/2574 = 2.1% hmm. I'm not sure if that number means anything, but it's the percentage of incoming packets that went awry in some manner.</div>
