4. Suppose you want to call a phone number outside of your building
using a phone station that is an extension from your PBX system (if
present). What digits must you dial? Often a “9” or “8” must be
dialed to “get an outside line” through the PBX (i.e., to connect to the
PSTN). Generally, “1 “or “11” or “0” must be dialed as a prefix for
calls outside of the calling code area (long-distance calls, national
calls, or international calls).
On a sheet of paper, write down the digits that you must dial before
you can dial a remote area code.
