VoIP not working

CherryPicker9999 — Mon, 17 Nov 2025 14:13:37 GMT

I upgraded to TalkTalk Full Fibre last Friday with an Open Reach connection (TalkTalk will not provide VoIP on City Fibre lines in the area, unlike Vodafone).

The "landline" phone is plugged in to the router.

VoIP does not work. If I call my own number, I get the message:

"This person's phone is not currently available."

I rebooted the router and there is no difference.
Any idea what the issue is?

(On my mum's home her Vodafone VoIP worked immediately on install).

Regards

Hi @CherryPicker9999

Assuming that you have the Sagemcom WiFi Hub 3, please open a browser and go to it's log in page of 192.168.1.1 (unless you have changed this IP address. If you look at the bottom of the page, what firmware version is it running?

Hi @CherryPicker9999

Thanks for that. Assuming you have the landline connected to the Phone port on the back of the Hub 3, that should be all you have to do. However, a simple check will see if it has registered or not. If you now log into the router. On the initial page, click on the Digital Voice tab on the left. On that page, it should show the Connection Status as Online and display your phone number (minus the initial 0) below that:-

Yes it is as expected.

TalkTalk told me there was a network connection issue at their end since Wednesday and their engineers are working on it.

It appears to have been resolved, as my phone now rings.

Thanks for your help.
