Set up Call Mode

You can handle inbound and outbound calls from your 8x8 Work for Mobile using a mobile data network or cellular network. 8x8 8x8 Work allows you to switch between the two networks based on your needs. For example, if you are roaming in areas with weak Wi-Fi signals or poor 3G/4G reception, you may experience poor call quality or dropped calls. By switching to a cellular data network, you can gain better call quality and a more reliable call connection.

To select a calling network option:

  1. Tap to open the main menu.
  2. From the main menu, go to Call Mode.
  3. Under Data Network, select the data network to use for your calls.
  4. Tap Outbound or Inbound to select the desired call mode.
  5. For outbound calling, select one of the following options.
  6. For inbound calling, select one of the following options:

The app automatically saves your selection.

Use Data Network for Outbound

If you choose to use the Wi-Fi/Mobile data network, calls are placed over a Wi-Fi or 3G/4G/LTE data network using VoIP. The call signaling and media are transmitted over the Internet.

  • Access to advanced PBX functions such as call recording, call transfer, call parking, and more.
  • Outbound call details including the call duration captured in the call log.
  • Does not incur cellular calling charges.
  • Call quality is dependent on the data network signal quality. If the signal quality drops, the call quality drops as well.
  • While on a Wi-Fi call, you must stay within the Wi-Fi network limits. If you leave the coverage, the call drops. An established call does not move across different networks.

Use Cellular Voice for Outbound

Calls are placed over the traditional cellular network. The caller ID at the receiving end displays the 8x8 Work number masking your cell phone number. At the termination of a call, you are automatically directed back to the app if you select to return to the app in outbound call mode.
