Fellow VM customers,
Since November friends and family with Sky mobiles (or landlines) have been unable to call my VM VOIP line. (The telephone is connected to our VM hub).
Making calls is no problem. It appears that numbers from other phone providers can get through, so it seems to affect only Sky numbers. When they call they hear an error message: "Sorry, that number does not exist." VM sent an engineer out and he confirmed all our internal equipment (hub, phone and line) is fine, so suggested it must be an external issue. Sure enough, he consulted his issue-checker, and noted that there was an outage in the area.
I see from Sky forums that Sky customers are reporting problems between the two networks. I even spoke to a Sky technician who seemed knowledgeable and friendly, but Sky place the issue firmly in Virgin Media's corner.
Virgin Media telephone support (stop laughing) acknowledge there's an outage in the area, but that's all they know and that's all they ever say. The field technicians have set 4 dates to fix it and failed 4 times. Each time they set themselves a new date and try again. They have a set a 5th resolution date of 3rd Jan.
There may be an outage, but in over 2 months VM can't actually confirm if that outage is responsible for this specific issue. So, we may be waiting for VM to fix a problem, not the problem.
Faulty hardware and wiring can account for degradation of service across the board, but this isn't across the board, it's specific to Sky numbers, so it seems more of a config issue.
So, if you're experiencing the issue, please comment. If you have insights that may help, please also feel free to comment.
(VM Mods, if all you can do is confirm there's an outage and repeat the next resolution date, please save your energy.)
