FAST 5364-3.T8 no longer enables Wifi-calling on Android mobile phone

I have a Sagemcom FAST 5364-3.T8 router, but it has the same software version SG4K100202 as others have reported this problem with.

All 3 of our phones are Motorola:

Moto G6+  Android 9
Moto G54  Android 14
Moto G8  Android 11
The phones work ok for wifi-calling on a friend's non-Talktalk router.
A friend's iphone works ok for wifi-calling on our router. 
 
We live in an area with no mobile signal, and rely on wifi-calling and don't have a spare router to try. I have read in another post that a live chat has resulted in the firmware being rolled back on their router, so I will try a live chat

Hi Alpacaman,

 

Thanks, but if you are going to be away it's probably best if we leave it for the time being but thanks anyway 🙂

hi Karl,

if we can do the test on Friday 4th then fine, but I am away for the next week so won't be using our router. I am unavailable 10.30 to 12.30 on Friday but can do any other time. Pete

Hi @Alpacaman 

 

We have made some changes to the firmware to resolve the Wi-Fi calling issue - would you be willing to test for us ?

 

Thanks  

Karl.

Hi

 

Our devices team have confirmed they are going to rollback the firmware shortly.

 

If you do use Whatsapp, can you confirm if whatsapp calls work as expected.

 

Thanks  

Karl.

I have now managed to turn off mobile data on my phone, and can confirm that I can still access the internet over wifi, and also that there is no wifi-calling icon, and as above I get the message "Mobile network isn't available. Connect to a wireless network to make a call". Simultaneously I have had an online chat and was told that it is not possible to roll back my router to avoid this problem. I have reset the router to factory settings, but when it restarts it is still on firmware SG4K100202  . We have a disabled person in our house and it is very inconvenient to not have a mobile phone signal.

Hi

 

If you look at the settings - usually swipe down from the top, the mobile data icon should look like 2 arrows, one pointing up and one pointing down.

 

Thanks  

Karl.

I don't know how to turn off mobile data, so I've put it in aeroplane mode, which is what I did at my friend's house to check that wifi-calling would work on his router. The wifi-calling icon appeared when I used my phone like that and successfully made a phone call using it at his house, but the icon does not appear when our phones are connected to our router. I used the wifi to read a webpage successfully as you suggested,  then tried to make a phone call. The message I get is "turn off aeroplane mode or connect to a wireless network to make a call".

Hi @Alpacaman 

 

Our device manager has also asked if you can confirm what mobile Network you are using.

 

Thanks

Hi

 

If you turn off mobile data on your phone, open a web page on the phone to confirm you are connected to your Wi-Fi and it's working, then make a call it should try to use Wi-Fi calling. 

 

Does this fail ?

 

Do you see the Wi-Fi calling icon in the notification bar of the phone ?

 

Here is a pic from my phone below - the Icon is the second one after the bluetooth icon.

I can't provide a screenshot as I'm on my laptop, but if I try to make a call on my mobile, at home (where we don't get a signal) a box comes up with the words "Mobile network isn't available. Connect to a wireless network to make a call" and an 'ok' button

Hi

 

If possible, can you PM a screenshot from the phone when Wi-Fi calling is failing.  You can usually capture a screenshot by pressing the power button and volume down together.

 

Thanks  

Karl.
