FAST 5464-2.T4 no longer enables Wifi-calling on Android mobile phone

[Greyman18]

I have a Sagemcom FAST 5464-2.T4 router:

   software version SG4K100202

I have been using this router with wifi-calling on my Android mobile phone for ~18months.   Note my Motorola phone has an icon which shows when wifi-calling is active. 

Since last week, my mobile phone cannot connect with wifi-calling.  I checked my phone by connecting to various other wifi networks (at work and friends) and it works as expected. 

Note - the FAST 5464 router appears to working as expected.  No other issues. 

Fortunately, I had a Huawei DG8041W-2.T5 router (supplied by TalkTalk), which was upgraded to the Sagemcom router when I got Full Fibre.   Wifi-calling works as expected with the DG8041W router.

So, my conclusion is that something is wrong with the FAST 5464 router.

Help please.

This would therefore sound like a bug in firmware V202, which has just started a gradual rollout to upgrade from V174. I have asked one of TalkTalk's support to pick your thread up and investigate it for you.
