This guide shows you how to place a call from the Keypad, choose which business number the other person sees, call back a missed caller or voicemail in two clicks, and call a teammate by name, with a labeled screenshot for every click.

A USB or Bluetooth headset gives the clearest sound. - Your Onyx Phone sign-in. An admin on your account sends it from Team; see Invite and manage teammates. - At least one line assigned to you. You can call only from the lines you answer. ## Step 1. Open the Keypad - Step 1.a: On your computer, go to onyxphone.io/login and sign in with your email and password. - Step 1.b: In the menu on the left side of the screen, click Keypad. It has a grid of nine dots next to it. - Step 1.c: Look at the top right corner of the screen. The Ready button with a green dot means this browser can place and take calls.

A list of the lines assigned to you opens. - Step 2.b: Click the line you want to call from, such as Minneapolis. - Step 2.c: Check the number shown under the box.

They see the business number of the line you chose in Call from. Your personal cell or home number is never shown. Once your business is verified, the line's caller ID name shows too; see Caller ID, call recording, and text-back. ### Which browsers can I make calls from? Current versions of Chrome, Edge, Firefox, and Safari on Windows, Mac, and Chromebook. The browser needs permission to use your microphone. See supported devices. ### Why is the Place call button not working? Check that you chose a line in Call from, that the number has 10 digits, and that the Ready button at the top of the screen has a green dot. If your browser blocked the microphone, click the lock or camera icon in the address bar and allow it, then reload the page. ### Can I call international numbers? Calls to the US and Canada are included. International calling is off unless you ask us to turn it on, at rates we quote in advance; contact us. Once it's on, type + and the country code before the number. ### Can I call 911 from Onyx Phone? Yes, from any line with a registered 911 address. Dispatchers see the address set for that line. 911 calls need power and an internet connection, so keep another way to call in an emergency. See 911 setup. ### Why can't I see a line in the Call from list? You can call only from lines assigned to you. Ask an account admin to add you to the line on the Team page. ### Do calls from my browser get recorded? Only if an admin turned on call recording for that line. Callers hear an announcement when a call is recorded. See Caller ID, call recording, and text-back.
