• 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!

Please contact the IT-ServiceDesk.

This may be an erroneous message.
If the room has not been removed by an administrator, open the Jabber chatroom tab and choose 'all rooms' instead of 'my rooms'.
Refresh the list there and check whether the room is available.

   2. enter 'cmd' and confirm you wish to open the command prompt.

Users who have logged off from all devices are unreachable if they have not otherwise informed the telephone system where the call is to be routed.
The way to do this is to set call forwarding.
Users can configure under which conditions calls should be diverted: This can also be initiated precisely for the case that one is no longer logged on to any device
See: Forwarding using the TK-Portal

• For use, a connection with the Cisco AnyConnect VPN client to the institute network is required.
• When making a Cisco Jabber call over a Wi-Fi network, if the audio signal on the call is only one-way, one should first verify that the Cisco AnyConnect VPN client is being used.
• If using another VPN client, make sure that this VPN client has been installed and configured using the appropriate third-party documentation.

• The display name change is currently only available upon request.
• Write a mail to servicedesk@itc.rwth-aachen.de with the following information:

Other than in the past, the new phones are no longer tied to a particular person and do not need to be moved with you. Instead, you will be able to log in to the phone* at your new workstation. Your personal phone number and any settings, such as configured speed dial buttons, will also be transferred to the new phone.

Please do not try to take the phone with you or to plug it in elsewhere. Do not unplug the phone or switch, because the port will automatically be locked by our security configuration and a reactivation is only possible through the IT Center. Please contact the IT-ServiceDesk in these cases.

*Applies for Cisco Telephones that are part of the new phone system.

The TK-Portal can be used to set up speed dials. Speed dials can also be saved and grouped on the Cisco Jabber client. Instructions for setting up and using speed dials can be found here.

The new telephone system also allows the phone book to be accessed via Cisco telephones and the Cisco Jabber client. These can be used to search for contacts and start calls. A guide can be found here.

Yes, it is possible to use a telephone number in conjunction with only the Cisco Jabber client software.

Cisco telephones should be used with a USB headset. Most headsets should come with appropriate adaptors. Should you require a new headset or an adaptor, please contact the IT contact person in your institute.

When using the standard configuration, the screen will be turned on automatically from 07:30 until 18:00. After this time, the screen will only remain illuminated for an hour after the device is used.

The angle of the phone can be adjusted by around 10 to 20 degrees. The silver stand of the phone can be adjusted accordingly.

An overview of the available telephony devices for the new system can be found under Cisco Phones.
