The phone is there for official use. It is not there to be tied up with personal calls. (There is a courtesy phone, campus calls only, in Speare 14 for people needing to call somebody on campus. Some public phones are in the Student Services Center.)
If you want to forward any calls to another phone while you are away from the Help Desk you can use the following. Here are instructions (from Cat Craig) on transferring phone calls.
Dial *3
Dial the extension
Hear weird tone, and then hang up the phone
Dial #3
Hear weird tone, then hang up the phone
Dial *2
Dial the extension
Hear weird tone, then hang up the phone
Dial #2
Hear weird tone, then hang up the phone
Remember, whichever * you choose, then use the same number with # to cancel.
The UC Office phone is an AVAYA D-Term (digital telephone). Some instructions for it's use can be found at ISD's phone web page . The instructions above for forwarding calls will work on the AVAYA (the forwarding is actually a function of the telephone switch).
