I awoke to a text message from Sky to say that they'd fixed the fault. I checked the router and noticed it was now sync'd at over 16Mb with a 3.1dB margin. One other issue I've been experiencing this week is that all incoming calls have a caller ID of "out of area". No doubt related to the general strangeness. I checked the caller ID and this issue at least still remains.
Shortly after I had a call from the customer solutions team at Sky to confirm. The guy I spoke to wasn't overly interested in this and didn't believe it was at all related. We couldn't troubleshoot anyway because BT's equipment is down today. Perhaps it will be fine tomorrow, but I'm unconvinced. We shall see.
I pressed for information on what had been done, which was no easy task. Eventually he said that BT had been running an intermittent line test, and this would have involved resetting the exchange port, which seems to have sorted it.
Time will tell, but what he did say is they've set my line to the profile for highest performance as the quality is so good, and they are seeing no errors at all. This is great, but let's hope the strangeness with the voice side of things is sorted.
