Landline showing no number calls every 30 minutes

[DavidReilly]

After changing over to TalkTalk full fibre, my house phone, which is connected to the Router, keeps showing NO NUMBER calls every 30 mins at 18 and 48 mins past the hour.  Please fix it asap.

 I have WiFi Hub2

I have updated my community profile - it shows

• Name
• Telephone number (mobile & Landline)
• Alternative contact number (mobile or landline - both are there)

From others with the same problem it seems you are having to fix every one of these individually.

I'd also like an explanation as to why this has happened

Thanks

Hi

It's a configuration issue, but not widespread, and our devices team are looking to see why this is happening.

Hi Karl that seems to have worked.  Can you tell me why this has been happening to people?

[Karl-TalkTalk]

No Problem 🙂

Thanks Karl - will let you know - next call is "due" at 11:48 - let's see...

Hi

I've made a configuration change to your router. 

Test over the next hour or two and see if this stops.

Thanks  

Karl.
