Network Settings
In the Network settings, set the location permission access for SSIDs and the network usage priority to ensure the call quality is optimal and that the data usage is managed properly.
Available Settings
On the Main screen, select 
> Settings > Preferences > Network:
- SSIDs - Tap the Grant button beside Location permission required to allow the location permission.
Service Set Identifiers (SSIDs) are the Wi-Fi network name and are specific to locations. When the application is trying to detect the available network SSIDs nearby the device, an access to the users location is required.
Allowed SSIDs and Disallowed SSIDs fields become visible after granting location permission.
- Allowed SSIDs - List the Wi-Fi network names that Groundwire can connect to and make or receive calls when the device is using these networks.
- Disallowed SSIDs - Set Groundwire not to make or receive calls via these Wi-Fi networks.
- Network priorities for RTP - Set Prefer Wi-Fi (default) or Prefer mobile data in calls using the real-time transport (RTP) protocol. Recommended to use Wi-Fi when the wireless signal is strong and stable and, to conserve limited mobile data.
- Network change strategy - Select to enable switching network option to If Needed (default), If different, or Always.
- Keeps cellular network active - Enable or disable (default). This is useful when the network provided by mobile data is stable and unlimited.
- Prevent Wi-Fi from sleeping - Enable (default) or disable. This keeps the device connected to the strongest Wi-Fi access point.
Open the Keypad tab, select

DNS Lookup
- DNS lookup - On the Preferences screen, enable or disable (default) Don't cache. When enabled, Groundwire performs a fresh DNS lookup every time the network conditions change or before every reconnection attempt. This is useful when the DNS results vary with the network the device is connected to.
