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?

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:
(We're also aware of reports of other handsets)
We will now look to explore the option to regulate the route cause, 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.

VM claim that the issue is the phones. Some of the phones, what about the rest, my phone is not on there list. Strange it's the phone's fault and not the VM system.
Come on VM come clean and admit that you system is lacking. I once again invite VM to supply me a phone to test if want to prove that it is my phone.
I think I have this correct but correct me if not:
If you look on BT website as I have recently done for my mother - I think when they have moved or are moving people to VOIP or digital they actually supply a new phone or are offering a range of phones to plug into the router. Should Virgin be doing this to combat this problem? Just a thought.
