Networks and ringing

At home, both on Wi-Fi

This is the best setup.

• LineFerry open or in the background: the call rings straight away.
• LineFerry swiped away: the gateway wakes your iPhone with an Apple push, and it rings. This needs the gateway to have internet, which it does on Wi-Fi.

Out, on the gateway’s hotspot

Keep the gateway in your bag with its hotspot on, and the iPhone joined to it.

• LineFerry open or in the background: calls ring normally. The two phones talk directly over the hotspot.
• LineFerry swiped away: on most phones today, the iPhone won’t ring. Here’s why. Without VoLTE, a phone drops from 4G to an older network for every call, and its mobile data pauses until the call ends. The gateway can’t reach Apple to wake your iPhone, and the iPhone, which gets its internet through the same hotspot, couldn’t receive the wake-up anyway.

So on the hotspot, leave LineFerry running in the background: don’t swipe it away. Missed-call and text notifications still arrive, about half a minute after the call.

A fix that works without internet is waiting on approval from Apple.

When no iPhone can be reached

If no iPhone has been connected for about a minute and the gateway is off Wi-Fi, the gateway switches to ringing on its own, like a normal phone. Calls don’t vanish just because your iPhone is out of reach.

As soon as LineFerry connects again, or the gateway is back on Wi-Fi, calls go back to your iPhone. The switch never happens during a call.

Several iPhones

One gateway can ring several iPhones. All of them ring; the first to answer takes the call and the others stop. In the gateway’s LineFerry app you can also choose a single iPhone to ring.

Changing networks

The iPhone remembers the gateway separately for each network, so moving between home Wi-Fi and the hotspot needs no setup. If the gateway’s address changes, the iPhone searches for it again by itself.
