That is because the breaking up for the most part sounds very much the same. It is a CODEC specialized for low bitrate transmission going into low bitrate compressions, packets being dropped entirely or arriving with a delay etc.
Who knows where such a thing comes from? It could be any number of things on a huge technological stack distributed over a large geographical area.
A domain expert should of course be able to distinguish various bad conditions by ear, e.g. clipping, saturation, wromg microphone distances/orientation, signal interferences, hum, bad grounding etc.
But not all people are good at analytical hearing regardless of them being engineers or not. That is why people pay the likes of me.
To say the network guru should automatically know the cause of a packet drop is like to say the postal worker automatically knows why the letter never arrived, or a doctor automatically knows the cause of that cough.
