I have an OS 500 with 2 Remote Sites

Both of the sites have about 20 ITP's with a High bandwidth Laser between them and the main site with less than 1mS ping times and loads of bandwidth to play with.

Users at one site complain about their display time being occasionally out by 1/2 hour or so but the other site users don’t. The phones in question are 51 series 7B ITP's.

I haven’t actually seen it myself they may just be extraordinary good wingers.
