To activate call-forwarding via the web interface, you must of course first log in to the interface. Your own telephone number is part of the address, so no universally valid link can be provided here. The link is structured as follows: https://4940428989xxx.phones.voicecoresystem.de To reach the web interface of your own telephone, the x must be replaced with your own number. For example, if you have the number 123, the link is https://4940428989123.phones.voicecoresystem.de
Enter the user password on the web interface. You can obtain the default password from IT.
If you have already changed the password, use your current password!
Danach sollte man die Umleitung einmal testen, indem man die Büronummer einmal selbst anruft!
