[SR-Users] Linphone push notifications (iOS) and kamailio

Yes, sure. Linphone sends registration, I detect it in kamailio and call
t_continue which results in INVITE going to Linphone. The thing is,
although iPhone get awake and linphone is open to the foreground it does
not accept the call based on the user action in the
"swipe/accept/reject" menu coming from the push notification. Nor it
allows me to directly  accept the call, it just puts it in wait and I
need to "click" through the menus to accept it. This is not intuitive
and definitely not user-friendly.

There seems to be another glitch as well. When I click my way to
accepting the call, there is no audio although SDP is perfectly fine
(same as when the iPhone is unlocked and linphone running). This leads
me to an idea that linphone need some sort od ID for the call in the
push notification. But I have no clue what it should look like.

Regards, Jan
