Classic desk phones are in private households in retreat. They are more often found in workplaces – whether by the self-employed or in small companies. And also ambitious home users want Gigaset make the concept palatable again. Curtain up for the Fusion!

Gigaset currently only offers the device in the Bundle with two handsets of type SL800H – Package price 500 euros. For those who already have enough cordless phones, it would be nice if the basic device could also be purchased separately in the future. Already on the equipment list, the Fusion presents itself as a real one all-rounder: with a 5-inch touchscreen, DECT base for up to eight handsets and DECT-ULE as a smart home center and USB-C socket for headsets.

But modernity also means that the grid connection of the Fusion takes place exclusively via IP – either via Gigabit Ethernet cable or via Wi-Fi 5 (11ac, dual band). The device can either be registered with an IP-enabled router or directly with the network operator’s SIP registrar. In our test scenario we have it on one AVM-Fritzbox 7590AX operated – the application describes Gigaset step by step in its Support-Wiki.

In this constellation, a few decisions have to be made: Should the up to five local answering machines of the Fusion be used, the one(s) in the router or, if applicable, the one in the network? The local variant reports incoming calls and messages in the App Gigaset elements also on the smartphone.

Configuration also in the browser

at Ideas can be carried out on the touchscreen, whose responsiveness is not inferior to that of modern smartphones. Or in the browser via an extensive web interface. The lush contact storage can be filled by directly importing an XML file or via Microsoft 365 and/or Google contacts.

Anyone who has saved the addresses in Outlook or Apple contacts must take the detour via the Cloud take. In conjunction with the supplied handsets, you can choose whether to work with a central phone book or with individual local contact directories for each device. Also custom ringtones for base and handsets can be uploaded via the browser interface.

Functions and contacts can be conveniently accessed, managed and used via the Fusion’s touchscreen.

However, the basic design for SME customers is then shown by the fact that the Fusion typical private functions like baby cry or baby monitor (room monitoring) not supported. However, it does not quite fit with the fact that it can also be used as a smart home basis for up to 64 sensors or actuators from Gigaset’s “OneX” elements range.

Important: If this function is activated, you have to do without Eco-DECT. On the business side, there are functions such as the option of setting up interactive voice menus (“IVR”) or connecting a headset via USB-C. You can also set which calls and notifications should be signaled on which handset in the base.

Very good

As convincing as the concept is, it seems functionality – or perhaps also their adaptation from the Gigaset Professional world – to demand tribute. When setting up and using the Fusion, we kept encountering small snags – the elements app only wanted to find the Fusion on the umpteenth attempt, then the internal one wanted to Answering machine do not accept incoming calls, occasionally ongoing phone calls broke off. The Check-Note We award “very good” in the expectation that future firmware updates will fix this.
