On Tuesday, February 13, 2024, the physical devices certificate of the TUphone telephone system will be replaced.
The telephone servers will be restarted several times. This will result in a re-registration of the landline telephones.
The devices must remain connected on this day.
A certificate exchange is only possible on connected, functioning and registered landline telephones.
Telephones that are not connected will not receive a new certificate and can no longer be used after the certificate has been replaced.
There will be no subsequent recertification of unregistered Cisco 8961 landline phones.
We are endeavoring to keep the interruptions as short as possible and thank you for your understanding.
