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


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?

Same here but only since we stepped up from Hub3 to Hub 5.  Same DECT phones as before but after the 1 Gig upgrade onto Hub 5 it's 10-20 calls a day (4 since lunchtime), no number, no ringing.   Really weird.

I have a business account with VM and been with them for over 20 years, I can’t leave as I am in a contract with them and tied in for another year. I have been getting these “no number calls” every 50 mins since I got my hitron router and my phone line had to be provided over ip. I don’t believe it’s a firmware bug as I would assume the firmware on a hitron router would be different from a hub 5. I have had engineers come out the same as everyone else and no joy. Support have the same playbook for home customers and business customers. BT phones is not the problem as I have just replaced my phones with BT and I had the problem with my older Panasonic. I believe its probably something to do with the DOCSIS network implementation.

can someone from the forum team here let me know if these is a forum for business I can search

So nothing new. I have replied saying it is an issue that affects others, so it isn't a case of sending a technician out to look at my hub and added a link to this forum. I have asked them to refer my complaint to to correct team to resolve.
VM have removed an invalid HTML (that they provided) from my message, but I don't think it detracts from their reply. 

Hi @Crystalgazer,

Thank you for the update. I'm very sorry to hear that you're unhappy with the response to your complaint.

I can see in the response you've posted that we've advised to contact the team on the contact number provided to notify them if you're unhappy with the resolution. Did you do that? If so, what was advised on that call?

At least yours was in reasonable English. Yet we still have the same old problem - platitudes but no further forward on a solution. This seems to suggest that the technical team have not yet triaged the issue, duplicated the error, formulated a solution, and devised a plan and timeline for a solution. You know, standard engineering practice for a technical service company that values its customers. 

For information - the complaint process - Start by logging a formal complaint with your provider.
1. Notice an issue with your provider.
2. Contact your provider to log a formal complaint and supply evidence to support your case.
3. Work with your provider to fix the problem. Get in touch and chase your provider for an update (disappointing that this has to be constantly chased and never volunteered).
4. Wait six to eight weeks for a resolution or deadlock letter. (I will be asking for this in the new year)

Then you can escalate the complaint to the ombudsman at
5 You escalate the complaint to the office of the ombudsman and they'll help resolve it.
6 The ombudsman will pass the details to your provider and they might resolve the issue at this stage. If not the ombudsman's office will propose what they consider a fair outcome based on the evidence from both parties.
7 They then ensure the provider complies with their resolution once you choose to accept it.
