How to Make Video Calls?

Before using video calls with Acrobits Softphone and Groundwire, ensure the Enable Video Calls setting is enabled. To place a video call, turn the camera on during the call. Or, touch and hold a contact or the Call button, then select Video Call.

Ensure that the camera permission is granted in your device settings for the application to use video calls. The following sections apply to both Acrobits Softphone and Groundwire.

Setting up Video Calls Mode

Before making your first video call, complete these initial setup steps:

  1. To open the SIP account screen:
    • Android devices - On the Main screen, select Android Settings icon > Settings > Accounts.

    • iOS devices - Open the Keypad tab, select iOS Setting icon > Accounts or SIP Accounts.

  2. Select the desired SIP account.

  3. Select Advanced Settings > Video codecs for Wi-Fi or Video codecs for mobile data:

    • Codec - Leave them as is.
    • Resolution - Select CIF or QCIF (default).
      Quarter CIF (QCIF) is lower quality and requires less bandwidth.
    • Bitrate - You may configure Minimum kbps and Maximum kbps, but we use an adaptive algorithm that adjusts to the network automatically.
  4. Select Back to return to the Advanced Settings screen.
  5. If disabled, toggle the Enable video calls switch to enable.
  6. Select a check icon or Done to save the setting.

After setting Enable video calls, you are ready to start making video calls.

Making a Video Call

If the called party's SIP client or device supports SIP video, the person receiving the call can accept the call in video format.

  • On the active call screen, select the Camera (1) icon to turn the front or rear camera on.

  • When the call is connected, the screen displays a large box with the received video and a smaller box showing the video sent from your device.
    If the other party is not sending a video, the screen displays the small box only. When you turn the camera off, the screen displays the larger box only.
