Lost is a delta in sequence numbers from one packet to the next. If you never receive a first packet you can’t lose any.

Well, some staff have moved to a demountable with a switch daisy-chained from another and it's happening quite a bit now. Looking at the CDR I can see that one end is just not receiving the packets. The phones are on the same subnet/VLAN, and the switch ports have no errors. I'm going to set up a span capture but does anyone have any suggestions on where to look?
