Before you can make an international phone call using your on-campus phone, you will need to have your long distance phone code entered into the Cisco phone system. If your code hasn't been entered, contact OIT at (303)735-HELP or firstname.lastname@example.org.
*Leave the receiver down while dialing*
dial phone number (including 011 and country code)
wait 30 seconds or so
screen will direct you to enter your authorization code
enter your long distance code (you may need to press # after you enter your long distance code)
wait about 40 seconds, and the call should go through
