Placing a Call/Fax – Dialing Sequence

Calling on-campus

Dial the 4 digit extension

Calling local or long distance numbers

Dial 9 + 1 + 10 digit number. If you hear a beep, it means the call is long distance and you must enter your authorization code.

Calling international numbers

Dial 9 + 011 + Country Code + Phone Number + the # key*. After the beep, dial your authorization code.


For faxes, you must typically enter the entire dialing string at once. This should work using the dialing sequences above. As far as the phone system is concerned, there is no difference between sending a fax to a number and placing a normal phone call. In fact, some fax machines have a monitor button which allows you to hear a dial tone and dial in real time, just as you would if you were placing the call with a phone.

*Entering the # key is optional for most phone calls (though it is typically necessary when using a fax machine), it just speeds up the process a bit. Because international calls have variable lengths, the phone system does not “know” when you are finished dialing an international number and therefore will wait for several seconds after you've finished dialing before issuing the beep for the authorization code. Entering # tells the phone switch that you've finished dialing and forces it to prompt for an authorization code immediately.

Authorization Codes

Authorization codes are provided to most new employees. All new authorization codes given out by the Office of Telecommunication are linked to a departmental GL number for billing purposes. Phone invoices will be posted online once a month. This invoice lists calls made with your authorization code, as well as other phone-related charges incurred during the month.
