WiFi calling drops out

[YorkiePete]

Recently I have experienced dropouts during WiFi calling. I have a Samsung A16 with Lebara SIM, Sky broadband router. The call connects, but either the person at the other end can't hear me, or briefly hears me before it cuts out. Download speeds is showing upwards of 250Mbps, upload around 90, so I don't think it's the stored that is the problem. Could it be that my phone is switching between WiFi and network connection? And how do I solve it? This has only started happening in the last week or so.

Hi @YorkiePete 

It would be useful if you could test it on another WiFi network to see if the problem really is with your home network, or your phone/lebara network. Is this possible at all?

I am experiencing the same problem with Wi-Fi Calling on my iPhone while connected to Sky Broadband.

The Wi-Fi connection itself appears perfectly stable and fast, yet Wi-Fi Calling can randomly stop working. Incoming calls may fail to arrive over Wi-Fi, or an ongoing call can unexpectedly drop Wi-Fi Calling and switch to the mobile network.

I strongly suspect that this could be related to the way Sky routers are configured or managed. Similar reports appear to come from Sky customers in different countries, using different phones and mobile operators, which makes me think there could be a common issue with the router or network configuration.

Perhaps certain Sky router configurations are not handling the persistent connections and keep-alive traffic required by Wi-Fi Calling correctly.

Hopefully, Sky can investigate whether this is related to the router configuration rather than simply Wi-Fi signal strength or internet speed

Hi @jamesn123 , just tried it at my parents in law, using their BT WiFi network - no problems at all! So I guess it's down to the router... Over to you, Sky!
