At HZB, telephony, which has a consistent external appearance, is essentially a complex interplay of several telephone systems of different age, manufacturers and technologies that are distributed to both sites (Wannsee and Adlershof) and connected to each other in different ways. The department IT-DS is primarily responsible for the operation of these telephone systems.

New telephony (Voice over IP)
We are modernizing and unifying HZB-wide telephony at the sites. The new telephony uses a completely different technology: Voice over IP (VoIP). The simple telephoning itself does not change. However, the new technology is more scalable, future-proof, unifies and simplifies the current telephone infrastructure and offers more possibilities for integration and adaptation in the HZB environment. We have already implemented these possibilities in a first step.
You can manage your phone from anywhere on the intranet using the My Phone-Portal web application.
In addition to central servers and components, new end-devices and telephones are also necessary for VoIP. These are rolled out step by step throughout HZB. Please understand that this takes a lot of time due to the quantity and individuality and that we determine the order based on defined parameters.
DECT over VoIP (cordless telephony)
In the new VoIP environment we now also provide a central DECT telephony. The uniform DECT telephones from Spectralink (optional with belt clip) communicate via radio (DECT) with base stations, which are installed at selected locations on campus. The base stations in turn communicate with the rest of the infrastructure via VoIP.
With this solution (compared to e.g. the Analog Gigaset DECT telephones) some comfort functions are added, e.g. signaling of phone number and name, a central phone book and central administration options.
