Sideline is designed to use the minutes from your carrier to let you place and receive calls. Included in the Sideline Subscription, you can use WiFi to connect calls over your internet connection as an alternative to using your cellular network.
When connected to WiFi, VoIP calling won't use up your minutes and will help you avoid any fees. You can find this in your Settings under "VoIP Calling".
Additionally, if at any time you are abroad, you can use WiFi to place calls to U.S numbers and not be charged for international calling fees or data.
VoIP calling & Call Quality:
If you have the VoIP feature enabled, and you are experiencing poor call quality, please disable and retest the quality of your calls.
You can also test by connection to a different WiFi connection to see if the level of call quality has changed.
Tip: Review the call quality reported on your dial pad within Sideline. If you notice a fluctuation in the quality we're reporting, or if the quality is lower than "HD" or "Excellent", this may show you that we don't indicate a consistently strong enough connection, resulting in poor quality VoIP calls.
Please note: Data and Internet connectivity are still required for general functionality. “Using your carrier network,” makes call quality more reliable than calls over VoIP or Wi-Fi.
If you have further questions on VoIP calling and any call quality issues you may be experiencing, please let us know.
