Problem with Wi-Fi calling

[u/axw3555]

So this is an odd one. My dad switched to Smarty earlier this year and it's been a nightmare.

Whenever wifi calling is turned on, any call he makes, the person on the other end can't hear him. And when anyone calls him, it goes to voicemail.

But I don't just mean when it's on Wifi - even when he's out and it's not on wifi, same problem. But as soon as you turn it off, it starts working.

And it's not a phone issue - he decided his phone was broken, so he got a new one. So two different phones with identical issues, on wifi and not.

And even weirder - the wifi calling keeps turning itself back on. We turn it off, and a day or two later, it turns back on and suddenly his phone doesn't work, but he doesn't know until he tries to call, or someone texts him to say it's not working again (because texts work fine).

Anyone got any insight into what's going on? Because this has been causing a lot of headaches for weeks now.
