For a G.711 stream with out telephony-event etc*, I'd say yes at the 
point in the network where the measurement is made.
E.g Tracing the in coming stream at the client(s).
But the end result to the user depends also on the ability of the codec 
to do error concealment.

*Wiresharks calculations may not be accurate in all situations.
Exporting the values and double check them in your own spread sheet 
wouldn't hurt :-)
