Voice Mailbox

All Information about the Voice Mailbox can be found here. Below you can read some quickstart procedure.

Request the voice-mail service

A personal Voice Mail service is associated to a personal telephone, that is: one that is used by one single person and is associated to this person in the ETHZ Mail Address List.

In this case, the first step is to request the voice-mail Service using the Nethz Tool:

  1. Go to old Nethz Interface at

  2. Select meine Services

  3. Look for the service Phone

  4. Below the title Aktion click on the button Voice-Mail aktivieren.


You will have to wait maximal 15 minutes until the service is registered and active. You will know that the service is active when you receive a notification mail from the voice mail service with your access PIN.

At this point, your voice mail service is configured, and you can access your mailbox via voice right away or make additional configurations by calling the number 38880 and identifying yourself with the PIN number received.

Use the voice-mail service

To use the answering machine function you still need to redirect your calls to the number 38880 in your desktop telephone.

Depending on your telephone set, it is possible to redirect your calls in the following three sceneries:

Those redirect options will have to be configured using your desk telephone. How to do it depends on the model you are using. Instructions on how to configure your desk telephone are published in the Informatik Dienste pages, in the Telephony section.

First Setup

It is advisable to customize your voice-mail, before using it. The first setup has to be done on the telephone. To perform this operation you will need the PIN you received in the notification mail.

  1. The first time you dial into the UM Service number (38880) you will be asked to set up your greeting and name identifier: Call extension 38880 (extern +41446338880) in your desk phone
  2. If you are not calling from your office phone, you will need to enter your 5 digit extension
  3. The automated system will pronounce your name and ask to you enter your PIN
  4. Enter your PIN and press #
  5. Follow the prompts to record your name in your own voice. This will serve as identification to your callers
  6. Follow the prompts to record a personal greeting, which will be played to callers when you are not able to answer. You can always change this later. If you do not record a greeting a standard greeting will be played instead.

The initial setup is now complete and you can choose to access your mailbox now or end the session.

You can learn more about available functions and configuration options of the voice-mail service in these documents:
