Hello
The Jabra Evolve 75 can be connected to two devices. On the one hand, with a USB adapter piece (included in the scope of delivery) to a PC or LapTop and additionally to a Bluetooth device such as a smartphone or mobile phone, provided this supports Bluetooth.
Personally, I have connected it to an AGFEO DECT 70 IP and to my tablet PC and make calls either via TEAMS or our telephone system.
Greetings
