Caller ID

The CU-Boulder campus default is to have outgoing Caller ID activated on all phones provided by OIT. If you need to change your phone's caller ID preference, contact your Telecommunications Liaison.

Dialing Tips

If you are dialing an on-campus number from a campus phone, you only need to dial the last five digits. University offices are 5-xxxx or 2-xxxx. Residence hall and family housing numbers are 6-xxxx.

You must dial an 8 before any off-campus phone number. From campus lobby phones, you must dial 7 first.
