If you have set up your X-Lite softphone, and either you can not hear your lead, or they can not hear you.
You may need to check your device settings in X-Lite.
First, check to see if your X-Lite Mute button has been activated.
If that doesn't help, you can check the device settings by clicking on the left dropdown and selecting "Options"
A new window will pop up, and from there click on "Devices" on the lower left side.
Under the Headset area, click on the dropdowns and select your headset for Speaker Device and Microphone Device.
Once those have been selected, click on Apply, then OK.
If your leads still can not hear you, be sure to check and see if you have a mute button on your USB headset that you may have pressed by accident.
If after these steps, either you can not be heard or you can not hear the lead, please call our support team at 630-350-0115 for assistance.
