Busy signal instead of dial tone
During a winter storm, we had a power outage. After the power came back on, our FiOS connection came back online...almost. We have TV and Internet (which I'm using), but our phone doesn't work. When we pick up a receiver, instead of a dial tone, we get a busy signal. I've unplugged each phone, one by one, and each phone (corded and cordless) still gives the busy signal. I've gone through all the troubleshooting steps I can find, resetting the router, the ONT, etc., but still we have the same problem. Thoughts?
