I thought VDSL bandwidth extended down to audible frequencies, however it begins at 25KHz and almost certainly wouldn't have been detectable in a common-or-garden handset.

I didn't like to plug a 'phone directly across the VDSL line because I understand NBN Co. is fairly ruthless about disabling any service which doesn't behave correctly, even down to supporting all the specified VDSL2 options and having them enabled.

The main surprise was that the POTS service was still functioning at all after cutover of the NBN service.
