New digital phone service changes the time and date on my phone

[trumpetman]

This is weird and yet another problem after my upgrade to 900mbps, digital voice and Eero 6.

I have a Panasonic telephone system (3 phones) that has been 100% reliable for years. Now after my upgrade to digital voice (Grandstream) the time and date keeps changing on the phone display.

I set it and all is fine for a while then it changes to 7 November 23 and the wrong time.

Strange I know and unusual but it can't be a coincidence that this started after my upgrade.

Hi Gliwmaeden2,

Thank you for the guidance. Being new to the forum and not overly system-literate I appreciate it.

Hi. I have a BT8500 cordless phone and never had any problems with it on a copper landline. When I switched to FullFibre +VOIP I immediately experienced a problem where if I viewed my calls listing it showed a 'No Number' ( not 'Number Withheld') call every 30 minutes exactly 24/7 but the phone never rang. After a month of investigation they found that it was down to a system feature within CityFibre that should have been off, and when they switched it off the problem stopped. 

Now I have an occasional problem where my phone rings and when I pick it up there is no connection and the screen legend says 'Power failure - check time/date'. The phone shows time/date as 12:00pm 2015 (default setting) and the calls listing shows a 'No Number' at 12:00pm. The caller does get through on the subsequent recall. I now find I cannot reset the date/time.

Update Tuesday 24/10/2023 - Carried out a full system power-down plus a hard reset of the router as recommended by Fibre tech support yesterday and I now have the original fault back; a 'No Number' call every 30mins. (registering on call listing but no actual ring) since the remedial action.

Hi there,

I'm really happy to hear this 🙂 I'm just waiting for the Devices Manager to confirm that a fix was rolled out, however it look like it may have been. I'll post again to fully confirm resolution to this. Thanks again for your patience with this while we were investigating.

Many thanks

Michelle 🙂

Yes, all is OK now. The date and time are both correct after an incoming call.

Well done for those involved.

Afternoon,

My colleague has also confirmed that it is now working for them too. @trumpetman would you mind retesting and confirming if this is also working for you please?

Thanks

Michelle

Hi again,

Thanks for trying and confirming. I'll ask the team now if they have made any changes since last week. My colleague was also experiencing the same issue so I'll ask him to retest too and will post back shortly.

Thanks

Michelle 🙂

Yes just checked it.

Morning John,

Does the time remain correct even if you receive an inbound call too?

Thanks

Michelle

 Morning,

The time is now right on our phone so they might have rolled an update out?

I am glad to find that it is not just me and it has been confirmed as a fault which is now being investigated with a view to correcting it.

I would like to commend Michelle for her continual updates.

I have the same problem with my Siemens Gigaset phone and Grandstream DVA, everytime its rung the time and date changes.

[Michelle-TalkTalk]

Hello,

The team have advised that they have replicated this and are now working on the next steps for a fix.

Thanks

Morning trumpetman,

We have a check in call with our Devices Manager this afternoon so I will ask for an update and hopefully have more info that I can share tomorrow morning.

Thanks

[Michelle-TalkTalk]

Morning,

I'm sorry to hear this. Our devices team are investigating and testing this at the moment so we're hoping to know more soon. As soon as we receive an update then we will post straight back here.

Thanks

I am still getting this problem, as described by other posts, that the date and time are corrupted in the handset on an inbound call.  Problem introduced on upgrade to Fibre 900 with Grandstream HT801 DVAs.  Same issue on two different handset models.  After a long time on Chat with Charles and Milarose, they thought it was caused by caller display not being active but it always was active. "Re-activation" of this feature by them both did not fix it.  They have escalated.
