Calls from on campus to off campus via long distance are not going through on the CenturyLink long distance service network. Dialing 8 + 1 is being blocked with an "all circuits are busy" message.
You can try dialing 9 + 1 + ten digit number instead. This normally costs more but your call will be routed differently. This will not work in all cases, but it may be a work around for your area.
CenturyLink is looking into the problem a this time. We will provide updates as they are available.
Incoming calls to the campus may or may not be blocked. This will be dependent on a number of factors between the originating caller and the campus. Results may vary on the incoming calls.
