No internet connection, strange dial tone

[#1]

My fibre connection has been down since yesterday evening, about 8:30pm. The dial tone I hear when I pick up the phone alternates between 2 difference frequency sounds, perhaps once per second. The phone works though.

This is odd behaviour and the first significant issue I've had for years. I've raised a support ticket, but heard nothing yet. Does anyone know what this might be caused by, and whether there is any way for me to get online?

Edit: Apologies, I've just seen there is another forum for fibre broadband. I don't see a way to delete or move the post though.

Do you have voicemail switched on? That results in a different dial tone, though wouldn't impact your broadband.

I don't know to be honest, we don't use the landline. I just checked for troubleshooting a thought it sounded odd so assumed it was a fault.

I've never heard the dial tone do it before, but the last time I used that phone may have been before I switched to PlusNet Residential (previously on Business).

If you can PM me your username I'll get this looked into.

Thanks, I've PM'd you.

Why not just dial 1571 and see if you a voicemail?

I wasn't at home when I posted so couldn't. I actually had no idea that was how you checked voicemails on a landline - grown up with mobiles and only have a phone line for broadband!

I had a voicemail, the dial tone has gone back to normal. Thanks for your help, just the broadband to sort now 🙂

It's working again now. Thanks to all those that helped.
