Hello,
I have a problem that my Android phone does not show the WiFi Calling option when I am connected to the WiFi of my RUTX50 with good 4G+ Signal.
I tried the suggestion regarding the Allow-IPSec-ESP and Allow-ISAKMP but it was already enabled and still no signs of WiFi Calling.
The router has the latest firmware and the phone shows the WiFi Calling function if connected to a landline WiFi Router.
I also attached my troubleshoot file. Here:
Best Regards
Marius
