    If I'm at home and my phone switches to wifi calling, the call will go silent and I have to hang up and call back. Is this normal? Its so frustrating especially when happening on a business call. Thanks.

    I had this happen to me so much back when it first rolled out it my area. A simple iOS update fixed it all and I haven't experienced it in months. Do you have any update pending on your phone?

    Who's your carrier? I live in a marginal area, and my AT&T phone likes to switch between Wi-Fi and VoLTE several times during a call. It's completely transparent. I only know it happens because I've seen a single call show up multiple times on a bill, alternating between Wi-Fi and "Shared Minutes" under "Rate Code".

    The same thing happens to me as well with T-Mobile. Its so annoying and I am fully updated.

    I'm on ATT. I tested something: During the middle of the call, when it went silent, I turned off wifi and it went back to cell and worked fine. For some reason when switching to wifi-calling the call goes silent even though the connection appears to be good.

    Hmmm. If you start a call on Wi-Fi, is there an issue?

    Does moving closer to your router fix the issue? Does it happen in other places besides your house?

    I have a strong wifi signal when this occurs.

    What about my second question? Does this only happen at home?

    For me at least, on my router (Asus RT-N66U), I've found 802.11n 5 GHz to be unreliable for Wi-Fi calling, and only let my iPhone connect via 2.4 GHz. Have you checked your router logs for error messages? What 802.11 protocol are you using, and what frequency?

    What I'm theorizing is that since you can swap back to the cellular connection successfully, the phone thinks it successfully connected via Wi-Fi. If you shut off your router's radio while the phone thinks it is connected to Wi-Fi calling, can you still switch back to the call on cellular, or has it dropped?

    That sucks, I haven't experienced it but I see no reason why it cant seamlessly switch from carrier to wifi calling without having to hang up and call again.
    Maybe a carrier update or ios update is needed to address this issue?

    It's because AT&T implemented cellular preferred with WiFi calling. So whats happening at times during your call you're getting a strong cellular signal, in which your being bumped back to the cellular network.

    Have you tried disabling and re-enabling Wifi Calling? I've used it since AT&T started allowing it and, yes, I do get a second or so of silence when it hands off between Wifi and Cellular, but never had it stay silent.

    I do have a cell booster (forgot what they're called). Not sure if that makes a difference.

    I have only noticed this at home but usually I'm only on wifi calling at home. I have he latest Apple router so I'm assume I'm on ac. Signal is strongest.
