with sipdiscount its mostly due to the fact that their sip server doesnt
respond in the predefined time set by 'qualify' in the peer definition.
If you do like   qualify=2000 it will only display them if they cant
respond within 2 seconds.  Which at night in LA is daytime where they
are located (Europe) and they probably see a higher call volume and thus
their servers arent as speedy to respond.

Note this number isnt the network lag by itself, its also the time it
takes for them to respond to sip messages, as well as the network lag,
so it can be midleading to performance by itself.

These types of errors are generally harmless, if they bother you set the
qualify to a higher number or turn it off with qualify=no.
