When the first incoming call after logging into the softphone does not go through frequently

Question

The microphone and speaker devices on the softphone are set to a USB headset, but usually in the first call, the customer's voice cannot be heard, and the agent's voice is not transmitted to the customer.

Answer

Possible causes for the issue: 

In such cases, if the call volume is very low, it may be related to the power-saving mode of the USB device.

If a USB device is not used for a long time, it enters power-saving mode.

After entering power-saving mode, the first use may take some time for initialization.

In the case of inbound calls, since the call is connected before the initialization is complete after power-saving mode, the issue of not hearing the call audio may occur.

Resolution method: 

Run "Device Manager" from the search box on the Windows taskbar, double-click on "USB Root Hub" under "Universal Serial Bus controllers," and uncheck "Allow the computer to turn off this device to save power" in the "Power Management" tab.
