Upgrade Telephone System / TISS Write Lock

An upgrade of the telephone system is planned for Wednesday, April 13, 2022. The TISS write lock must be activated for this. The write lock is expected to be active from April 13, 2022 8:00 a.m. to April 14, 2022 12:00 a.m. During this period, no TUphone changes can be made in TISS.
The reason for the upgrade is a problem with the push notification for Cisco Jabber for iPhone. A successful upgrade should solve this problem.
In the meantime, service interruptions may occur. We apologise for the inconvenience.
