Hi @Irfaan,
Thank you for your post and welcome to our community forums. We're here to help.
I am so sorry to hear that you're facing some issues with your landline service and are unable to hear a dial tone. I've checked the systems on our end and I can't seem to see any issues on the line currently to explain this. As such, I'm going to send you a private message in a few moments to take a few extra details from you.
Please respond to this at your earliest convenience and we can go from there.
Thanks,
