Role : EveryoneDuration : 2 minOn : Web, Mac, iPhone, Android

Before you start

  • A microphone: the computer’s, or better, a headset.
  • A stable Internet connection.

Step by step

6 steps, about 2 min
  1. 1

    Plug in your headset

    10 s

    Plug it in before the call. With a headset, the customer’s voice doesn’t come back through your speakers: no echo.

  2. 2

    Open the audio devices

    10 s

    At the bottom of the left sidebar, next to the language, click the headset icon, Audio device. The Audio devices menu opens.

    Left sidebar/Audio device

    Open this screen in Callizy
  3. 3

    Allow the microphone

    20 s

    The menu shows Allow microphone? Click it, then accept the browser’s prompt. Without this permission, the other person can’t hear you.

  4. 4

    Choose the microphone and the speaker

    20 s

    Under Microphone, pick your headset’s; under Speaker, where the sound goes. Just plugged in a device? The Refresh button reloads the list.

  5. 5

    During the call

    10 s

    Mute: the customer can no longer hear you; Unmute turns it back on. Nobody can hear you? Check this button first.

  6. 6

    In the app

    10 s

    During a call, the sound button sends the voice to the speaker, the headphones or a Bluetooth device. On Android, it opens Audio output.

Key points

  • The microphone and the speaker are chosen in Audio devices, at the bottom of the left sidebar.
  • The browser must be allowed to use the microphone.
  • A headset plugged in before the call gives the best sound.

Not working?

The other person can’t hear you
  1. Is the microphone muted? Click Unmute.
  2. In Audio devices, choose the right microphone. Allow microphone shows up? Click it.
  3. The browser blocks the microphone? Click the icon to the left of the address, then allow the microphone for app.callizy.ca.
You can’t hear the customer
  1. In Audio devices, check the Speaker.
  2. Check the volume of the computer and the headset.
Callizy shows “No microphone detected”
  1. Plug in the headset, then click Refresh.
  2. Still nothing? Allow the microphone in the browser, then reload the page.
Callizy shows “No speaker detected”
  1. Some browsers don’t let you pick the speaker: the sound then plays through the computer’s audio output.
The sound cuts out or crackles
  1. Check your Internet connection: weak Wi-Fi cuts the voice.
  2. Stop videos and big downloads during the call.
  3. The banner says “Reconnecting the phone…”? Callizy is reconnecting: wait a few seconds.
The customer hears an echo
  1. Use a headset: your speakers send the customer’s voice back into your microphone.
Callizy shows “Microphone permission required to call”
  1. On Android, open the phone’s settings and allow the microphone for Callizy.
