Singtel Wifi calling

[vade]

Yes, Singtel CSO just called me to tell me that they have fixed the issue and it’s working as of this morning. I’m not at home so can’t check. Anyone else can confirm?

Confirmed that Wifi calling is working now

Not working still, don't see "Singtel Wi-Fi Calling" on my iPhone. Restarted my iPhone, Airplane Mode, toggled Wi-Fi Calling on off too..

It's back. Noticed this when I am connected to a Singtel based Wi-Fi. Other places with M1 or StarHub based Wi-Fi connection, Singtel Wi-Fi calling only appears briefly, around 5 seconds then it disappeared.

Now I am connected to a Singtel Fiber based Wi-Fi, Singtel Wi-Fi Calling has been around for 1 hour plus, quite stable, even toggling on and off the settings works properly.

I noticed on my m1 fibre connection i need to be on airplane mode to force wifi calling.

Yes I tried this, works for a brief moment, 3 to 5 seconds later the Singtel Wi-Fi Calling disappeared.

over the years.. wifi calling has been my yard stick of sorts for a properly configured and working home network.

over the years i had issues with wifi calling due to:
1) looney dns resolver
2) firewall / packet mangling / QoS
3) wifi related issues (latency, packet loss...)
4) singtel wifi calling terminating servers failures

all i can say is ... if working properly, once connected to wifi, wifi calling will be established in a few mins automatically. I do not need to toggle to airplane mode. Also, it is independent of the isp.. unless latency or routing or something else is screwed up. for reference I am on VQ.

the troubleshooting is truly a PITA.. as it is dependent on a whole host of factors and conditions.

Singtel cellular profile on recent versions of iOS is set to prefer cellular connection if the signal strength is good. cellular signal need to be really poor before your phone will establish a tunnel back to their ePDG over wifi (wifi calling).
