+++ Update from 19.03.2025: The Cisco UC update could not be carried out due to a technical problem on 18.03.2025. The problem was identified and fixed today. As a result, there will again be restrictions on Jabber login, the presence function and chats today (19 March). Local telephony should only be affected for a short time, if at all. +++ Due to an upgrade of the Cisco Call Manager, there will be a temporary interruption to telephony services for Cisco devices. Ongoing calls will be disconnected. The outage is expected to last between 5 and 30 minutes. Logging into the Jabber client may also be unavailable for up to 60 minutes. We are working to keep the disruption as short as possible. Alcatel phones are not affected.
