Cant Call Out Long Distance, Receive Long Distance Calls Or Call Cell Phones.

When I tried to call out long distance today & gave me a busy signal before I could even get the number completely dialed. Can't call cell phones local or long distance. All the phones in Witts Springs Arkansas are doing this. I don't know if a lines out or what, but my dads in ICU an hr from me & I have to be able to receive calls from the hospital incase something changes. He's on a ventilator & not doing very well at all. We need this isse fixed ASAP. It's literally a matter of life & death in this case. Please have someone come fix our phone lines.
