It's how it's run, but I can't help thinking half the problem is the ISP - the big ones tend to be rubbish if there's the slightest problem as they just have fixed scripts to follow.
When we got fibre, I took the opportunity to switch ISP - Plusnet went downhill badly under BT ownership. Despite having run a couple of trials many years ago, showed no signs of supporting IPv6 - on top of other issues. So I ditched them and went with Zen - not the cheapest, but you can get hold of humans who actually have the ability and empowerment to deal with issues (I cocked up the ordering first time around
)Oh yes, and Zen don't force you to use a crappy locked down router. You can use your own, but the Fritzbox is a fairly decent router.
While I took Zen's VoIP service for the main house number, I went with Andrews & Arnold for a couple of other infrequently used ones
