Thanks for coming back to us, I am sorry you've got a fault with your landline, could you explain what is happening when you try to call to your mobile please?
I have some troubleshoot using these links below – No Dial Tone troubleshooting Cant connect calls
I also want to ask a few questions just to make you’re your home setup is all okay, can you please tell me –
If your phone is plugged into the mains or an extension?
Is your HUB performing okay? The landline works through the HUB in most cases, so if your internet has gone off, your phone line might have ceased to work too.
Have you got a different handset to test the line with? If yes, please have a go and let me know if it improves things.
As I told you, when I use the phone I try to plug in main landline, also the internet is working properly. It doesn't problem with internet. I was trying to use the phone my neighbour' s house plug just in case, it was working.
However, you sent me the link it doesn't reach as well.
Please give me easy way or I'll give my phone number so you can call me if possible. Let me know
