You can use the phone device to punch in an entire number (e.g., 95551212) then either lift the receiver or press the speaker phone button to dial the number.
If you are on campus, you dial five-digit extension numbers. Extensions beginning with an 8 denote administrative/faculty numbers. Extensions starting with 3 indicate non-direct extensions (e.g., elevator phones or phones in residence hall lobbies).
Off-campus local calls
Dial 9, then dial the desired number (e.g., 95551212).
Direct dial long distance calls
Dial 9 + 1 + Area Code + seven digit number (e.g., 916085551212).
