Hi @LHouston, thanks for your post although I'm sorry to hear that your landline isn't working at the moment.
I've ran some checks for you and there doesn't appear to be any identified area problems so we must treat this individually.
As you've tested different phones I'll send you a Private Message to ask you to confirm some further details, so we can get somebody out to you to assist.
Please expect this message to arrive shortly and respond when you can!
Many thanks
Tom_W
