Quick call is a feature used to make calls that show your business number. It's used alongside of cell or landline forwarding, but can also be used with your deskphones or softphone apps.
Quick call can be accessed from the main page on your account. Clicking on the Quick Call Icon shows all your most recent calls in a list as quick callback options.
Clicking on the Dialer Icon pulls up a dialer screen for any numbers you'd like to manually dial. After selecting the green phone icon to the right of a recent call, or hitting the blue dial button in the dialer, you'll see 'Connecting you now' at the top.
Any phone active on your extension/user will begin ringing. Once you answer the call, it will begin sending a business call from that phone.
If the device you want to make the call from doesn't ring, please check that its enabled in 'Receive Calls At' section found on the top right. The Web Application and mobile app can only make direct calls when a desk phone, cell phone, or mobile app like Zoiper are installed.
