Conference calls

The IFI Voice-over-IP instrastructure provides a web-based conferencing solution. You may setup a conference by following these steps:

Point your webbrowser to the URL if you are connected inside the university or if you are connected via VPN. Then click the “Conferencing” link.

You will be presented with the “Web-MeetMe” page.

Click “Add Conference” on the left side.

Login using the e-mail address configured as SIP Alias which normally corresponds to your IFI e-mail address. The password corresponds to your primary password. Both parameters can be found in the welcome e-mail / paper you received.

Now you may setup your conference. The most important parameters here are “Conference Number”, “User PIN”, “Start Time” and “Duration”. You may keep the conference number at the random value already provided. The PIN is an additional secret that callers must know to participate in the conference. Choose when the conference should start and how long it will take. It is a good idea to enter a longer duration than expected as the conference may otherwise be unexpectedly shut down when this time is exceeded.

If you define a “Moderator PIN”, you may use this PIN instead of the user PIN to participate in the conference. You then have more options available, like being able to kick participants from the conference and setting the volume. These moderator options are available by pressing the *-key on your telephone during the conference.

By clicking “Invite to conference” one or several times, you may enter the names, e-mail addresses and phone numbers of users you want to invite to this conference.

By clicking “Add Conference”, the conference is created. A preview of the intivation e-mail will be displayed which you may change if needed.

By clicking “E-Mail Participants”, all participants entered will receive an inivation e-mail. An invitation looks similar to this:
