FAQ - Webex
The correct e-mail address is already displayed in the TC portal and in Webex. However, the error message "Your account is not authorised. Please contact your administrator".
This may be due to the fact that the Webex account was only recently created. It may take up to an hour for the data to be fully synchronized in the system.
Please be patient at this point. If you are still unable to log in, please try the following:
- Log out of Webex.
- Close Webex completely. Also via the taskbar
- Try logging in again via Single Sign-On.
- The login should now work.

Then follow the instructions in the app to log in again.

The e-mail address can be freely selected from the addresses displayed in the TC portal. The selected e-mail address also corresponds to the e-mail address used for the Webex account.
Options:
Selection of the work e-mail address. If an e-mail is stored for the person in the personal directory, this can be selected. (If a person has two entries, e.g. at two different institutes, both e-mail addresses are also available for selection)
Selection of the personal RWTH e-mail address. If a personal RWTH e-mail address is available, this can also be selected.
If neither an official e-mail address nor a personal RWTH e-mail address is available, a cryptic @webex e-mail address is available for selection.

If the Webex client does not generate an audible ring despite correct device settings, it is necessary to deactivate the "Softphone-Client Desktop" setting in the TC Portal and reactivate it after a waiting time of around 10 seconds.
You must then completely exit the Webex client by clicking on "Sign out" in your profile (see point (1) in the Webex user interface). You must then log in to Webex again. Logging in to the Webex client is done via the primary e-mail address displayed in the Webex account in the TC portal. You will then be redirected to the RWTH Single-Sign On, where you enter your user ID in the format ab123456 and the corresponding password.
If this does not work, the computer must be restarted. Webex should then ring clearly.

The synchronisation of Webex and Outlook calendars is not yet optimal. After the meeting has been deleted in the Outlook calendar, it still exists in the Webex calendar. This is also the reason for the notification.
As a workaround, the appointment in Webex must also be deleted manually.

The synchronization of the Webex and Outlook calendars is currently not yet optimal. After the date of a meeting or meeting series has been changed in Outlook, it is not automatically adjusted in the Webex calendar. This results in the wrong notification.
The following workarounds are available:
1. The creator of the meeting or meeting series cancels it and creates a new meeting or meeting series.
2. You deactivate the notification function (Aus) for meetings in the Webex settings. This means that you will only receive the correct notification for a meeting or meeting series in Outlook.

Webex offers a very high level of security and data protection for meetings and chats. All meetings, calls and chat messages between Webex clients, RWTH telephones and combiantions of the two are encrypted. This means that telephone calls via the RWTH telephone system with Webex softphones or desk phones are also encrypted and are made exclusively on RWTH infrastructure.
To increase the level of security, the key management for all RWTH Webex participants is also operated locally on servers in RWTH data centers.

In the following situations, there is a possibility that the implemented security measures can be bypassed:
Situation: The host allows people to dial into their meeting via the public telephone network.
Recommendation: As all telephone calls in the public telephone network, i.e. landline and mobile networks, are usually transported unencrypted, an attacker can listen in on the connection. We therefore recommend not allowing people to dial in via the public telephone network for confidential calls by selecting the "private meeting" meeting type.
Situation: The dial-in details for a meeting have become known to third parties, allowing unknown persons to attend the meeting.
Recommendation: As the host, check your list of participants. If necessary, exclude unknown participants. And lock the meeting in the meeting menu so that new participant requests end up in a lobby.
For particularly confidential discussions, we strongly recommend using the "private meeting" meeting type, which only allows invited participants from the RWTH network.
Situation: If your end device is compromised by a third party, there is a high security risk for any communication with it.
Recommendation: You should use end devices and operating systems that are maintained by the manufacturer. Use up-to-date software and virus scanners on your end devices.
Situation: If third-party recording devices are in the same room during a meeting, your communications can be overheard.
Recommendation: Be aware of your surroundings and potential eavesdroppers.

- If you want to reach a phone number within the RWTH, it is sufficient to dial the last 5 digits of the phone number, e.g. instead of +492418012345 only 12345.
- For external numbers either start with the prefix code "0" or with "+" and the corresponding country code, e.g. 00241... for Aachen or 00031... or +31... (for the Netherlands)
- This also applies to cell phone numbers.
- These rules also apply when setting up call forwarding!

The new telephones are no longer personal, but are assigned to a specific workstation. If you change your workplace, the phones will remain at your old workplace.
After the move, use the phone at the new workstation by logging on to the phone with your user data. Your phone number and individual settings are now stored on the new phone.
Important: Do not unplug any cables from the phone or the switch, otherwise the data port trap will be automatically blocked by our security configuration. The devices can then no longer be used. Reactivation is only possible through the IT Center. Please contact the IT Service Desk (servicedesk@itc.rwth-aachen.de) for this purpose.
