VoIP - Frequently Asked Questions

This document answers some of the common questions about UW Oshkosh VoIP service.

VoIP stands for Voice over Internet Protocol. Since August 2017 this is the standard phone service on the UW Oshkosh campus.

Will my phone work during a power failure?

Yes, for at least a limited duration, depending on the building in which the phone is located. Most campus buildings are attached to an emergency backup generator. If the power goes out, the generator starts up and will provide power for as long as needed. However, there are nine campus buildings that were not able to attach to the emergency generator grid: 3rd Avenue Grounds, Campus Center for Equity & Diversity, Ceramics, ERIC, MEC, Oviatt, Pollock, Radford, and Titan Stadium. The network closets in these nine buildings are equipped with small battery backup systems. While this battery backup is not enough power to maintain operation of your computer, it is enough to maintain operation of your VoIP phone. We expect the battery backup power will last approximately 30 minutes, but it depends on the load it is experiencing.

Will we still be able to use 4-digit dialing on campus?

Yes, but only when calling between campus phone numbers with the 424 Oshkosh prefix.  Calls within or between campus phones with the 832 (Fox Cities) and 929 (Fond du Lac) prefix may use the 7 digit phone number. 

Will we still need to dial an access code to make off-campus calls?

Yes. There will now be a single off-campus access code - 81. No more trying to remember if the call is long distance or not.

Will I have voicemail?

Yes. Voicemail is available on all lines at no additional cost, unlike the old system. If you had voicemail or an answering machine in the past, your VoIP phone was setup to include voicemail. If not, and you wish to request it now, please contact the Help Desk (, 3020).

I've forgotten my voicemail pin. How do I change it?

NOTE:  This only works for the voicemail tied to your NetID.  Contact the UWO Help Desk if unsure.

  1. Login to the VoIP Self Service Portal at using your NetID and password.  
  2. Click on Messaging Assistant
  3. Select the Passwords menu at the top
  4. Select Change Pin

Will FAX machines work on the VoIP system?

Fax machines will not be converted to VoIP for data security reasons. They will remain as analog line service, which may cost more per month. A multi-function printer with copy to email capability might be more efficient than a fax machine.

    If you need further assistance please call the Information Technology Help Desk at 920-424-3020, put in your own request at, or email
