A:Answer Hi there! The CS520 was designed for office desk phones; However, there is a way to make it PC compatible, just by getting the APU-75 cable which provide USB connectivity to the charging cradle. As long as the APU-75 is selected as default under sound settings (playback devices and recording devices), you should be able to listen and talk through conference calls. As for having Remote Call Control, most likely you won't be able to answer/end/mute calls directly through the headset. Some programs/soft phones provide this feature by default, and some have been integrated and certified to provide this feature by installing our Hub Software on the PC. In this case, Verto Communicator is not listed: https://bit.ly/3lIEaja. If you have any further questions, feel free to contact our Customer Care Team at: 1-855-765-7878
