Broadband Phone usage?

[#1]

I use VOIP with gradwell having moved from PN broadband phone when it was killed off. I have just checked my usage tonight and in the totals in the table at the bottom broadband phone is mentioned with various amounts of usage. The bars on the top chart  show nothing.
Has anyone else seen broadband phone usage appear. I thought voip would show up as normal usage if it was not PN BB pHone not that ever showed before.
Any ideas?

any voip traffic identified will appear in the voip column.

It's never been picked up before. They must have fixed something.
