It would be interesting to find the pattern... is it certain devices? Time of day? Call volume?

We've got several dozen ata's, ip phones and pbx systems using a combined total of over a hundred thousand minutes per month.

So if there are problems, we're going to hit them. Whereas other users may never notice.

It is mostly our pbx locations that have the problems, but those locations also have our highest call volumes too.

@christcorp - What kind of voip devices are you using? How many calls (minutes) per month do you make?

Same questions to everyone else.

Maybe we can find a pattern.
