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

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

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.

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
