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.<br>

And also some code snippets of a modification of "kamailio.cfg" to add support for ios push notifications. (see below).<br>

Could someone have this already working? Or kamailio official developers could add this by default inside source code?<br>
