The problem is a bit different. When the phone is NOT in foreground everything works. The problem occurs in Foreground because the phone does not send a REGISTER when receiving a PUSH notification in this state. So if the phone is in Foreground, it does not receive the call because I do not send an INVITE unless I receive a REGISTER (where I can get the updated address and port). Also for sequential requests such as RE-INVITE and BYE they may eventually fail because the NAT mapping is closed after some time. The RFC specifies the pn-purr for this purpose, but I'm not sure if Linphone supports it.Cheers,Flavio E.

Hi,
In the last weeks I have been testing the support of Linphone and OpenSIPS
to the RFC8599. I have managed to make everything work except for the calls
in Foreground.
The process of the RFC8599 is to send a push and wait for the REGISTER
before sending a new INVITE (this is necessary because the address or port
could have been changed).
However, when the phone is in foreground (IOS) after receiving the PUSH
notification it does not send the REGISTER, because it was not awake.
Another issue I have to workaround, is to handle three registrations after
a PUSH. One I got to suppress by changing the setting of the repeat call
notification to off. Because of the two REGISTERs, two INVITEs are
generated and a 486 busy comes from the phone. I had to drop one of them in
the proxy to make it work, but it is a horrible patch (the REGISTERs came
with different call-ids).
My questions are:
Is it possible to send a REGISTER after a PUSH even in the foreground?
Is it possible to send only one REGISTER after the PUSH rather than two? I
have pcaps and logs
of all the tests.
Best regards,
Flavio E. Goncalves

Flavio,
Actually, we've faced something similar that you are describing, correct me
if I'm wrong, it's about CallKit showing dial screen and even after sending
REGISTER by app, the app might not receive an INVITE, cause call is ended
already.
We've overcome it with
https://blog.provoip.org/2021/03/kamailio-and-delayed-cancel-on-ios.html
(On Kamailiio, but I don't think it's critical here).
Not sure if it's what you're looking for, but it's the way we got it
correctly working.
Cheers,
Ihor
