Hello,
As mobile applications based on kamailio are growing exponentially on Play Store and App
Store, i would suggest if you could add by default the code for ios/android push
notifications.
I have problems mainly for incoming call (phone wakeup) on linphone iphone app, as
kamailio is missing the push solution. On Android i am using Baresip and works perfect
without push.
Navigating on the web, i found some uncomplete or minimum tutorials to implement this.
Like: https://denys-pozniak.medium.com/apple-push-notification-with-kamailio-eeca…
And also some code snippets of a modification of "kamailio.cfg" to add support
for ios push notifications. (see below).
Could someone have this already working? Or kamailio official developers could add this by
default inside source code?
