Hi Koji,
For me at least I had to setup a DNS server to resolve
erable-f.orange.fr and aes.orange.fr [I was using a SIM card that looked
like Orange France] One was for Android and one for iPhone, i forget
which was which,
and then implement an Entitlement Server to allow Wifi Calling, only
then did the WiFi Calling option appear on the device.
I recommend you capture all the packets on the WiFi AP [openWRT is great
for this] and see what DNS queries the device is making.
Admittedly this was a number of years ago and things could easily have
changed in the meantime.
Regards
Alan

Hi Alan,
Thanks a lot for the info.
It seems the entitlement server is used for the operators to control
the access to WiFi calling if their subscriber is allow to use it. My
question is on the step before using the entitlement server.

As i recall, iOS uses an Entitlement Server to determine if WiFi
calling
is available on the network.

Hello experts,
I am trying to use WiFi calling in iPhone by using
sysmoISIM-SJA2, but
for some reason "WiFi Calling" toggle
button is not shown in the
phone
setting.
I am using PLMN ID 441-216 (Newly obtained from Japanese Government
for private network usage).
I have written epdgid, epdgSelection, and pcscf address in the SIM
card and saw if the toggle button was shown, but it was not.
It would be really appreciated if you could tell me how to
enable WiFi
calling in iPhone.
Thanks&Regards,
Koji
