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.
