Selecting your playback and recording devices in Cisco Webex Cisco Webex gives you the option of selecting your Speaker and Microphone devices. This will enable you to play back a callers voice in your headphones, desktop speakers, or other devices. You will also be able to choose which device is recording your voice, whether it's a microphone on a headset or a microphone built into your webcam. The tutorial below will give you step-by-step instructions for changing these devices. Open the Webex application. At the bottom left of the application window, click on Call settings. A small pop-up window will open. Click on Open Call Preferences. A new Settings window will open. Click on the Audio category on the left side. You will see several categories that you're able to adjust. Ringers and alerts - Whichever device is selected will broadcast the ringing sound when you have an incoming call. Selecting All Devices will broadcast the ring from all audio devices that are connected to your computer. As an example, if your computer has external speakers and a headset, then your speakers and headset will both chime when a call comes in. If you only want your headset to chime when you have an incoming call, select your headset from the drop down menu. If you only want your external speakers to chime when you have an incoming call, select your speakers from the drop down menu. Speaker - Whichever device is selected will broadcast the callers voice. Microphone - Whichever device is selected will be the device that captures your voice. Click Save at the bottom of the settings window to finish.
