Telephone: Student General Phone Service

Overview

Listed below are basic steps for Call Waiting, Caller ID, using Authorization codes and more student phone features.

NoteThis document is for student use only.  Not all student housing locations include in-room phones.

Authorization Code (authcode)

An authcode is a personal 7-digit number that is required for making direct-dialed long-distance calls from a residential phone. Your authcode is specifically assigned to you and your U-M Student Identification Number. Using your authcode ensures that billing for long-distance calls is personalized and secure.

To obtain your code you will need your uniqname and UMICH password before contacting UMphone Student Services.

For further assistance with billing information contact Telephone Customer Service.

IMPORTANT! Do not share your authcode with anyone.

Campus Telephone Exchanges

To dial a number that begins with one of these exchanges from a 565 telephone, you must dial all 7 digits. If you are dialing from a non-565 campus telephone, you must dial just the last 5 digits. Other campus exchanges are 232, 615, 647, 763, 764, 936, and 998.

Caller ID

The Caller ID feature requires use of a Caller ID display phone or a Caller ID display box.

  • Residence Halls:

    • Once you have a Caller ID phone or device, it must be connected to the modular jack outlet (for voice) just below your current wall telephone.

  • Northwood Apartments and Lawyers Club:

    • If you have a telephone with Caller ID, simply connect it to the telephone jack outlet.

    • If you have a Caller ID box, connect it to the telephone jack outlet first; then connect your telephone to the box.

NoteOnce Caller ID is properly installed and connected, this device will start displaying caller information before you answer the call.

 

What display information will I see?

The information displayed will depend on the information that is made available.

  • Calls from on-campus

  • Calls from off-campus

  • Log of Caller Information

  • Call Waiting Information

What display information will others with Caller ID see about me?

  • Calls to on-campus locations

    • When you call an on-campus number that has a Caller ID device connected to it, only your room phone number will appear on the recipient's display screen.

  • Calls to off-campus locations

    • When you call an off-campus number that has a Caller ID device connected to it, either a U-M default number (647-0000 or 665-6555) or the name "University of Michigan" will be displayed.

What if I use my long-distance authcode or a calling card number?

If you purchase a Caller ID device that retains last number dialed, you should delete any history of calls made using either your authcode or a calling card number, since this information will be retained in the log. Please refer to manufacturer's manual for your device for instructions on how to delete last number dialed.

Each student assigned an authcode is responsible for maintaining the security and privacy of his/her individual authcode.

Call Waiting

  1. Press and hold the switch hook for one second, then release.

  2. Make sure caller is still on the phone.

  3. Press the switch hook to return to caller.

Note: The call-waiting tone is a short tone every ten (10) seconds. If you do not answer the call-waiting tone, the calling party continues to hear ringing until the third ring and then is transferred to voicemail.

To Cancel Call Waiting Permanently

You can have the Call Waiting feature removed permanently from your phone by contacting Telephone Customer Service.
