Constant "no number calls" since moving to IP Telephone from landline (Home) (Resolved)

[Chris_Myers]

My area has recently been migrated from landline to IP telephony which seems to work well with one exception.  My received calls report 10-20 daily calls from "no number".  There is no call made (no ringing) and no message left, just a report that "no number" called and a time.  OFCOM state it should be addressed to the provider and the Telephone preference service state they can do nothing with marketing or computer generated calls.  This did not happen until switched to IP telephony and has been daily since (coincidentally - I think not).  This appears to be a man-in-the-middle network attack and is therefore worrying (as well as filling my recent calls with rubbish).  Virgin media say they cannot see these calls, yet their system records it on my recent calls log. Anyone else having this problem or have a resolution?

Hello to anyone in the VM Forum Team / Mod Team,

On Saturday 1st April I posted 2 messages on this thread, message number 693 and 699 both on page 70 and got response. Please can anyone in the VM Forum Team / Mod Team look at those 2 messages and give me a response.

Hi @GC1028  and all, 

Thank you for your patience whilst we continued to investigate this issue.

Our Voice engineering teams have concluded that the "no number" issue is device specific and not a global issue.

The route cause is located on the handsets’ sensitivity to power fluctuations received from the Hub. 

Here is the list of handsets we tested:
 

• Gigaset C530A Trio Digital Cordless Answer machine
• BT8600 Advanced Call Blocker
• BT Decor 2600 v2
• Panasonic KX-TGJ424EB Digital Cordless Telephone with Nuisance Call Blocker and Answering Machine, Quad Dect

We will now look to explore the option to regulate the power output, however, this needs to be discussed with the our equipment vendors and may take some time to come back.

As always we will continue to update you along the way.

Kind regards,

Community Moderation Team

Theirs a far longer list than that, and someone in the group listed them.

I hope it's fixed soon as next contract renewal probably end the landline altogether as when you are trying to make a call out and a ghost call is coming in handset says like in use due to this and clogging up the call log.

You never know maybe fixed with hub 6

I beg to differ on the fact that it is Device specific (Ashleigh_C).
If you read my earlier posts you will see that a Friend who lives less than a mile away, with exactly the same equipment as me (phone, hub, etc), has not get the problem at all, I have even swopped my phone for his with no issue, his end !.
Lets stop keep repeating ourselves on here, chasing our tail with a problem that you know all about, and have done for many, many months.
You have been told so many times now, it's becoming an embarrassment to you an all concerned, get this sorted once and for all !

[Chris_Myers]

Yes it is device specific. The type 5 hub is generating power fluctuations picked up by several telephone systems. It is NOT A PROBLEM WITH THESE DEVICES, WHICH WORKED BEFORE BEING PAIRED WITH HUB 5. Again VM caused the problem, it is for VM to fix. So again we ask, stop spouting the party line and tell us what solution VM is providing. Please!

[Chris_Myers]

Oh, and just to add salt to the wound an answer that incorrectly amounts to “it is the customers fault not ours” does NOT mean that the issue is resolved. VM may be happy to absolve themselves of responsibility, but I can assure you, those of us on this forum are far from satisfied and our issue remains unresolved to our satisfaction. I suggest this is passed to the top of the tree and not just to the engineering team who seem unable to engineer firmware.

Re: post #711, within post #401 in this thread there is a suggested "fix" for this problem that works on other devices. Can someone in the engineering team tell us if anyone has bothered to apply these changes to the Hub 5 configuration (not user configurable options) and if the list of impacted devices have been retested to identify if the issue of Ghost Calls then goes away? If the answer is yes, then can someone tell us why this has not yet been rolled out?

Has anyone tried call diversion on Virgin Media landline ?

Do the ghost calls go through to the diverted number? (The phone only needs to be connected for 150 if ever needed).

There is a charge For £2.25 a month.

PS This service should be free if user a has an HUB 5 (until fixed)

[Chris_Myers]

Kind of defeats the object. I could just bin the landline and stick to using my mobile. The point is this “enforced improvement” has failed, not “it’s OK if there’s a workaround”.

[CEEJAYTHEDEEJAY]

You have completely misunderstood my post.
What I said was that, my mate who has the listed hardware, is not in anyway affected, and his devices are working as they should be.
Therefore there may well be people out there that are not affected by the hardware changes.
